TRANSFLUID manufactures three-phase, permanent magnet, synchronous electric machines (PMSM Permanent Magnet Synchronous Machine) with natural convection air cooling for its hybrid modules. This solution ensures high efficiency and simplicity with limited weight and size.

The electric machine PMSM is controlled by a Motor Controller (Frequency Drive) that allows the electric machine to work both as a motor and as a generator. The integration of the range of electric motors with the controllers allows for a compact installation of the system and makes management easy and effective during any operation phase.

The structural characteristics of electric machines are optimized for specific use in hybrid systems up to 3000 rpm. The system is cooled by conventional air cooling making an easy on-board installation, and permitting you to harness the power progressively for its whole range of revolution. The torque curve which characterizes these types of motors at low speed can be three times the nominal rating which can be very useful for vehicle start up. In the range of medium speed, up to about 1500 rpm, the torque delivered can be as twice as much as the nominal rating for a limited time. In marine applications, this is very useful for low vessel speed maneuvering.



The Tier G engine can be purchased as a standalone component, or even better can be purchased with the complete set of accessories (management unit with display, battery, inverter, electric box, pedal, CANbus cables, etc.) making it a plug&play solution to redesign an existing vehicle, vessel and boat or conceive a new one. Do not hesitate to contact us for further details and a suggestion for your new propulsion system.
In addition to purely electric propulsion, the Tier G integrates the range of Transfluid electric motors used for hybrid solutions, giving the possibility of reaching up to 200kW of electrical power with the installation of two engines on the hybrid modules of the HM series.
