alternative to conventional resolvers Amphenol PSCI-4PP-05 inductive emotor rotor position sensor
Product Overview
The PSCI Inductive eMotor Rotor Position Sensor provides accurate feedback on the angular position, direction, and speed of the rotor shaft, essential for optimizing motor inverter control and maximizing electric engine efficiency. Designed for high-speed applications, this sensor can be mounted on the same shaft as the electric machine rotor. It is immune to electromagnetic stray fields and offers precise rotor position measurement within a compact, lightweight, and fully sealed package. The PSCI sensor is a cost-effective alternative to conventional resolvers and is suitable for harsh environments, offering robustness to tilt, misalignment, and air gap variations. Its true power-on sensor technology ensures excellent accuracy and precision.
