Super Silent System

Special transmission system created for military use. The transmission not uses a mechanical epicyclic gearbox but a transmission through a special belt.
The noise drops below 20 decibels.
The belt is built with special materials to prevent skidding during operation.

Line Isolator

On TESEO it is a line isolator mounted that is used to activate the power supply to the power board.
The disconnector is placed near the trigger in a vertical position.
In case of switched on electronics block the disconnector is able to cut power to the board and stopping the machine.
The disconnector is designed to withstand 250 A peak and does not allow the welding of the contacts.
The system also uses a security control performed by the Teseo firmware that in case of gluing no longer allows the system startup.
The isolator must be used in all those situations in which the diver must either leave the scooter (penetration into narrow spaces) or to carry out transactions in which the driver will only be a hindrance so before putting it in the pull position must be locked so do not run into unwanted ignitions.

Drive with right/left hands

The machine has the same balance to right and left because it is mono guide.
It is mounted a special non-slip handle large dimensions which allows comfortable grip with any type of glove.
The machine is balanced perfectly with the vertical handle that allows you to maintain the same weight balance for righties and lefties.
This feature allows you to avoid twisting when propeller starting.

 

Opening system and rapid extraction

Patented system for the rapid opening and extraction of the bow cap and battery.
The system has hooks that allow the closure and the rapid extraction of the battery.
The hooks are fixed to a steel band where are adjusted.
The thickness where the hooks lock is designed to break down to an internal pressure of 4 bar in case there is gas inside the Teseo.

Perfect Balance Stabilization System

The system composed of diver and scooter must present between the various features also to be perfectly neutral and in alignment at any depth.
The Teseo all have this basic feature due to careful planning.
the scooter in neutral buoyancy is easier to maneuver underwater, this key feature adds comfort and safety to the diver.
The Teseo is delivered neutral in fresh water.
In the passage from freshwater to sea water (and vice versa), the scooter must be rebalanced.
This operation of TESEO is extremely fast and easy thanks to the unique weighing system (weighing fast change)
once positioned is attached to the body of the scooter just below the battery

Battery Type

On TESEO series find use different types of batteries:
The types of batteries are of two types:

  • Nickel metal hydride: The rechargeable battery nickel-metal hydride (commonly said, but inappropriately, nickel-metal hydride), abbreviated NiMH (English: nickel-metal hydride), is a kind of similar to the accumulator nickel-cadmium battery (abbreviated Ni-Cd ), but the anode, which absorbs the hydrogen, is an alloy instead of cadmium. As in NiCd batteries, nickel is the cathode. A NiMH battery can have two or three times the capacity of a NiCd battery of the same size and the memory effect is less significant. However, the volumetric energy density is less than the Li-Ion batteries, and the self-discharge is greater.

  • Lithium ions: The lithium ions can be constructed in a wide variety of shapes and sizes, so as to efficiently fill the available spaces in the devices that use them.

These batteries are also lighter than the equivalent made with other chemicals - often much lighter. This is because the lithium ions have a density of very high charge - the highest of all the ions which develop naturally. The lithium ions are small and mobile but storable more quickly than those of hydrogen. Furthermore a battery based on lithium is smaller than a with hydrogen elements, such as nickel metal hydride batteries and with less volatile gases. The ions require less intermediaries for the storage, so that it is possible to allocate to the charge instead of the overhead for a greater share of weight of the battery.The Li-ion batteries do not suffer from memory effect. They also have a low self-discharge rate of approximately 5% per month, respectively, compared to the beyond 30% monthly and 20% per month of nickel metal hydride batteries and nickel-cadmium. In fact, the Li-Ion batteries do not have processes of self-discharge in the usual meaning of the word but suffer from a slow permanent loss of capacity ,. On the other hand, the Li-Ion batteries will self-discharge slowly, because of the small consumption of the voltage monitoring circuit inserted in them; this consumption is the most important source of self-discharge in these batteries. A stack to Li-Ion single never be dissipated in some tension, to avoid irreversible damage. Consequently all systems that use Li-Ion batteries are equipped with an AUTOMATIC CUT OFF circuit that shuts down the system when the battery is discharged below the defined threshold.
Batteries are all equipped with overcharge protection and underdischarging managed by the Teseo firmware.

 

Mechanical clutch

It is the terminal part of the mechanical transmission.
The clutch combines the propeller and the propeller shaft and is able at propeller blocks disconnecting the two systems, allowing the engine to turn and maintaining the propeller stops.
There is across the Teseo series increasing its security.
In the case of the system for the rapid extraction propeller PROP FAST REMOVE the mechanical clutch is calibrated and left on part of the fixed hub.

Propeller

On TESEO can be mounted on different types of propellers in addition to the standard:

  • propeller with 3 fixed blades ABS (standard)

  • propeller with 4 fixed blades ABS

  • propeller with 3 fixed blades Carbon

  • propeller with 4 fixed blades Carbon

  • Prop Fast Remove 3 blades ABS

  • Prop Fast Remove 4 blades ABS

  • Prop Fast Remove 4 blades Carbon

 

Carbon Kit composed of Prop Fast Remove 4 blades Carbon and Carbon conveyor

Prop Fast Remove

During the past year in Eudi (March 2016) it has been proposed our new fast propeller extraction system.
The system consists of a part that remains fixed on the carrier (the hub, inside which is located the mechanical clutch) and the propeller, which through a convenient ring nut can lock in one piece on the hub.
The removal procedure is very simple and fast ... you unscrew the ring - when the dowel pins out from home you rotate the propeller until it comes out. All this is possible because the helix is removable in one body and can be done with one hand as you can see in the video below.
For replacement as simple procedure ... I rotated the propeller to screw until the dowel pins are in place - then turn the ring nut until it stops.

Controllo Temperatura

 

Thermal Control Battery
Security system essential for the use of NiMH batteries and Li-ion.

At the inside of the battery packs a temperature sensor is mounted which is able to release the power in the phase of charging and discharging of the cells if for any problem would start to heat up beyond a certain threshold to prevent the explosion of the same.
The reactivation of this sensor is possible by the engagement of the battery charger.
A second sensor connected to the control card (always on the battery) set at a lower temperature serves to avoid tripping during operation.
Automatically reduces the maximum speed giving us as the ceiling Safety Speed order to bring down the critical temperature without ever reaching the value set on the first sensor.

 

Thermal Control Motor
 

Connected to the control board have a thermal sensor that monitors the engine.

Upon reaching a first temperature threshold intervenes the card and blocks the use of the maximum speed as ceiling giving us the Safety Speed

Safety Speed

It is the security speed (set by means of the soft).
Standard is set around 80% of the maximum power of Teseo.
The safety speed of the scooter will be used as maximum speed if you are having the temperature alarms (battery or engine) or battery life Alarms (25%).
In both cases automatically no longer allows the use of high absorptions in order to cool or to do so to increase the autonomy of the scooter before shutdown given by Cut Off.

Alarm 50% - 25% - 10%

With the soft you can set different alarm thresholds for the battery life.
In RC the only threshold is 10%. On reaching the Teseo has a vibration of temporal length and frequency programmed to enable us to understand the alarm is reached. At this point the board automatically takes the maximum gear and allows us to use the Safety Speed.
In the TRS and BM series special attention has been given to the interaction between the machine and the user to achieve pre-established limits.

  • battery alarm 50% with the possibility of exclusion by software.

  • battery alarm 25% not avoidable.

Both alarms are independently programmable from the control software so as to be able to separate perfectly by the diver the nature of the alert.
They are programmed through the adjustment of the tones and the times thus creating a distinct vibration on the machine for the two different alarms.

  • Detachment maximum speed alarm 25% and use Safety Speed

 
 

Cut Off 

Security system is essential for the use of new NiMH batteries and Li-ion born for protection from underdischarging the batteries.

The board is capable of measuring the battery voltage and to the achievement of a predetermined threshold power to the motor is cut.

The threshold is defined by the technical characteristics of the battery manufacturer Going below this value would render the cells unusable.

One feature that is currently present only on Teseo scooter is that this function is intelligent in that it is possible to restore the operation from the line isolator and start to proceed at a lower speed that allows a lower current absorption and thus an increase of the voltage measured.
The scooter is able to recognize the consumption for which the system is reactivated until it intervenes on the minimum voltage and minimum consumption.

.

Separation motor/battery

 

Inside the body of Teseo exists a dividing bulkhead that allows the separation between the battery and the engine compartment.

Bulkheads found in Teseo series are of two types:

  • In RC separation not sealed bulkheads.

  • The second made of aluminum is mounted in all models.

Structural type as designed to resist on its entire surface to the pressure of a possible flooding 150m.
This is also used to cool the engine.

 

The motivation of the division between the compartmentss is the need to ensure separation between the battery and the engine compartment to avoid contact between the electrical and the chemical that could make gas.
Secondly, the division makes safer as it generates a strong reduction of the volume in the event of flooding.
The third reason is security not to come into contact with water throughout the scooter electronics.

Water Alarm Engine Compartment

 

The engine compartment is not inspected by the user, there are positioned the sensors that are activated by the presence of water.

 

Just a teaspoon of water to activate the sensors.

 

When you connect the battery a buzzer (warning) will begin to buzz to indicate water inside

Control Electronic Absorption

The Teseo is able to measure and control the maximum absorption during the operating phase.
The most important part of a scooter in our opinion is the battery and what we tried to do from the beginning is to find ways to preserve itself by an excessive effort to improve its functioning and life.
The engine needs to run current.
Depending on the speed of use, we will create a load on the battery will have to respond by giving us current.

Each cell composing the battery can withstand an maximum allowable load that if we go to overcome for some time can create permanent damage.
We define a maximum load through our EC system and if we went during the operation for various reasons to overcome this load set Teseo will make an adjustment such that the load required is cut to the predetermined value.

Magnet Permanent Motor

On TESEO  RC and TRS series is mounted a permanent magnet motor.
The electric current passes in a wrapping of turns which is located in the rotor. This wrapping, composed of copper wires, creates an electromagnetic field to the passage of current.

This electromagnetic field is immersed in another magnetic field created by the stator, which is characterized by the presence of one or more pole pairs (magnets, electromagnets, etc.) Said brushes. The rotor starts to rotate by electromagnetic induction, since the magnetic field tends to align the rotor to the stator During the rotation of the system constituted by the brushes and the collector switches the power supply of the windings of the rotor so that the magnetic field of the stator and the rotor never reach the perfect alignment, thus you are obtained the continuity of the rotation.

On this type of engine is mounted as an option the ES system (Emergency Start).

Brushless motor

On the BM series is mounted a brushless motor.
The brushless motor ("brushless") is a DC electric motor with permanent-magnet rotor and the rotating magnetic stator field. In contrast to a brushed motor thus does not need of sliding electrical contacts (brushes) on the rotor shaft to operate. The switching of the current flowing in the stator windings, and then the change in orientation of the magnetic field generated by them, is done electronically. This results in a lower mechanical strength, eliminates the risk of formation of sparks with the increase of rotation speed, and greatly reduces the necessity of periodic maintenance.

In a brushless motor, the rotor is free of wrapping. to realize the rotation of the magnetic field generated in the stator, an electronic circuit, comprising a power transistor bank controlled by a microcontroller which controls the switching of the current, switches the inversion current and therefore the rotation of the magnetic field. Since the controller must know the position of the rotor relative to the stator in order to determine the orientation to be given to the magnetic field, it is usually connected to a sensor.

The efficiency of these machines is on average higher than in asynchronous direct current motors.
The first significant advantage relates to the expected life of the engine, given that the brushes are the "weak point" of an electric motor. The absence of brushes also eliminates the main source of electromagnetic noise present in the electric motors in direct current.
The size is small compared to the power that can be delivered and especially compared to the couple that these engines are able to deliver. In terms of efficiency, the brushless motors always working in optimal performance conditions. Not having to generate the rotor magnetic field have higher efficiencies. The absence of sparks is essential when the engine operates in environments saturated with volatile chemicals.

The main disadvantage of this type of motors is increased in cost. In contrast to brushed motors, in fact, the check is performed electronically by a controller, an electronic device provided by the engine manufacturer or by a third party, then the cost of the motor must be added the cost of the control system.

Deep

The series RC is built to be used up to a depth of 100m.
The TRS and BM series are built to be used to a depth of 150m.
This depth has been reached with both operating i tests in diving that with the aid of a hyperbaric chamber.

Each material used is certified for resistance to that pressure.
mechanical strength calculations were carried out for the design of each particular and especially for the type and number of the seals.Some details have been tested on a static stress machines to simulate high breaking loads resisting solicitations to almost double compared to the design calculations.
Great attention was also imposed on our suppliers explaining the difficult conditions of use.

Materials

The TESEO are constructed of materials suitable for use marine.

  • Conveyor - prow cap - retro high-density polymers.

  • Body high thickness PVC.

  • Body marine aluminum anticorodal with deep anodizing

  • INOX mechanical details.

All parts are designed to withstand external efforts.

All the TRS and BM series using this dedicated software for program and check the DPV (32 or 64bit OS Windows  for Mac use Virtual Machine)

 

The user version is an option that allows the diver to save the configuration of various types of dives (wreck, cave exploration) in order to manage and prepare the machine with one click.

 

The driver interfaces with the PC through a USB cable that comes with the DPV ..

 

The interface allows to manage the firmware (the operation mode Linear or sequential), the number of speed, the rpm at each speed, the types of alarm, the modulations of the alarms, the acceleration curves, soft check battery status and burning test

Emergency Start

System for emergency direct connection between the battery and the motor.
The system is mountable on all of Teseo TRS series that use permanent magnet motors.
The ES is composed of an additional switch that is mounted on the opposite side of the normal switch.
The procedure of use is extremely simple:

  • Execute the mechanical release of the switch

  • Turn it in the direction marked

  • at this point the engine will be able to function bypassing the electronic control circuit.

Still remember that it is an emergency and  not for the normal use of the scooter.

Maintenance

The maintenance required to be carried out once a year on the DPV are:

Replacement of O-rings of the closing.
