SKF Commutation Sensor-Bearing Units
Three digital commutation signals for 6 step-drive control

The units are customizable to electric motor size and number of pole pairs. The sensor body can be angular-shifted in order to align the output commutation signals with the E-motor back electric magnetic force.
Combined functionality benefits
SKF Commutation Sensor-Bearing Units integrate sensor function into the bearing – an SKF patented design that allows very precise management of the sensor-bearing unit air gap. The result? The units are insensitive to severe magnetic field disturbances, and can withstand application vibration and continuous temperatures up to 150°C. Other design and performance benefits include:- Compactness
- Simplified assembly
- Sensing performance unaffected by assembly line mounting tolerances
- Optimized torque ripple and system noise
- Excellent e-motor torque stability
- Improved safety and reliability
