E-Motor
120kW / 130Nm
The 120kW E-Motor is a synchronous permanent magnet motor / generator primarily intended for hybrid and electric vehicles. The unit is powered via a high voltage three-phase electrical connection from an inverter, such as McLaren Electronics’ MCU-500.
An advanced liquid cooling scheme allows the motor to achieve sustained high power operation given the unit’s modest size and weight.
When combined with the MCU-500, and powered from a 535V DC bus, the unit can be controlled via torque and/or speed demands via a CAN bus. The same performance characteristics can be achieved in motor and generator modes of operation.
