Piher’s Rotor Position Sensor employs an inductive eddy currents principle, ensuring exceptional precision and reliability. This sophisticated technology generates angular target position signal directly, eliminating the need for complex algorithms and external circuitry. The sensor’s compact design makes it an ideal fit for even the most space-limited applications. Its lightweight and small size, ensure seamless integration into a wide range of electric vehicle architectures.

The sensor assembly consists of two key components: the sensor itself and the target. The stationary sensor is securely mounted to the motor stator, while the target is attached to the rotor. As the rotor spins, the sensor detects the induced eddy currents in the target, enabling it to calculate the angular position with exceptional accuracy.

Beyond its exceptional accuracy and direct angle output, Piher’s Rotor Position Sensor offers several key benefits for automotive engineers:

Compact Size and Lightweight Design: The sensor's compact and lightweight form factor makes it ideal for space-constrained applications within automotive vehicles.

High-Speed Performance: Capable of handling speeds up to 600,000 electrical revolutions per minute (el rpm), this sensor ensures seamless operation in demanding automotive environments.

Robustness and Reliability: Built to withstand harsh automotive conditions, the sensor features immunity to stray fields, susceptibility to misalignment, and variations in air gap.

Protection from Electrostatic Discharge (ESD) and Short Circuits: The sensor's integrated protection safeguards it against potential electrical hazards, ensuring reliability and durability.

Configurable pole pair number, connectors, sizes and protocols. 

Piher’s Rotor Position Sensor provides a versatile and accurate solution for monitoring EV/HEV BLDC motors rotor position. This real-time data enables precise control of motor operation, leading to optimized efficiency, enhanced torque delivery, and reduced emissions.
