Sensor units for motor control of hybrid and electric vehicles
Units for direct drive control
Units for sine wave control
For sine wave control, SKF supplies sensor bearing units providing the shaft angle position in real time within the entire motor speed range. These integrated units provide a signal comparable to the one provided by a resolver and can therefore be used by the motor controller’s software. The shaft angle position is communicated via a sinus/cosinus signal.
SKF can adapt the electronics to comply with the interface of the application. The units can provide either an analogue or a digital encoder-like output signal. The units are more compact and cost-effective than inductive resolvers. They are easy to mount and do not require special shaft or housing accuracy.
