Piher’s High Speed Inductive Position Sensor are used by hybrid/electric vehicles powertrain systems to feedback the angular position, direction and speed of the rotor shaft to optimize control of the motor inverter.
The position sensor can be mounted on the same shaft as the electric machine rotor and sensing its position accurately is critical in order to drive the motor optimally by the vehicle’s control unit.
This solution provides high speed rotary motion sensing with a robust design against external magnetic interference fields generated from sources such as electric motors.
It uses the physical principles of induction in a wire loop and eddy currents to detect the position of a solid metallic structure that is sliding or rotating above a set of coils consisting of one transmitter coil and two receiver coils.
Custom product design packaging can be provided to meet any form, fit and function including the choice of wire harness and interface connector.
