Inductive eMotor Rotor Position Sensor

Accurate feedback on the angular position, direction, and speed of the rotor shaft is essential to optimize control of the motor inverter and drive the electric engine with the best possible efficiency. With lower weight, smaller dimensions, immunity to stray fields and comparably lower cost, Piher Sensing System’s Inductive High-speed eMotor Rotor Position Sensors offer a true alternative to conventional resolvers. The possibility to perfectly customize the sensor to the motor dimensions enables more flexibility in the development of the electric / hybrid powertrain of the future.
