Stand-alone, contactless, active sensor providing the speed and direction of the asynchronous motors by detecting the rotation of a ferromagnetic encoder wheel mounted on the rotor shaft. The speed signal is required to drive the torque of the asynchronous machine through the inverter control board.
Benefits & Features
- Provides the direct sine and cosine of the electrical angle to the inverter
- High speed and low delay
- Standard mechanical design independent of e-motor’s number of pole pairs
- Covers single-ended or differential outputs upon request
- Integrated sensor protection against harsh external environment
- Amplified output for EMC robustness and long cable harness
- ASIL C (ASIL D possible on request)
- Robust design - overmolded tight sensor IP6K9K
- Low current consumption
- Reduced number of parts for easy and cost-efficient assembly
- Reduced weight and size compared to resolver solution
