TRANSFLUID manufactures for its hybrid modules three-phase, permanent magnet, synchronous electric machines (PMSM Permanent Magnet Synchronous Machine) with natural convection air cooling. This solution ensures high efficiency and simplicity with a 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 perfect integration of the range of electric machines with the controllers allows for a compact installation of the system, as well as 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 in a progressive manner 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.
