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, Inductive 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. Inductive sensors use the physical principle of induction in a wire loop and eddy currents to detect the position of a solid metallic target rotating above a set of coils. This allows a reduction in parts and higher design flexibility (e.g. through-shaft, end-of-shaft and arc configurations). Furthermore, inductive eMotor rotary position sensors can be designed to be ASIL-D compliant on sensor level.
