APM 120R Electric Vehicle Traction Motor
Equipmake has worked in collaboration with AIM Japan on the development of a world class leading motor for electric vehicle traction applications. The APM 120R is an interior permanent magnet motor, utilising Samarium Cobalt magnets. It achieves the high power density through a combination of direct oil cooling of the stator, and forced rotor cooling.
The motor has a maximum speed of 12,000 rpm. The achievement of this speed with this design of motor is the result of a novel rotor construction, which has been patented by AIM. The motor has the option of an integral epicyclic gearbox, enabling straightforward installation in a vehicle application.
Equipmake has developed an inverter matched to the motor for optimum performance.
The power density of the APM120R is class leading.
