Abstract
An example apparatus as discussed herein includes a controller. The controller receives control input indicating how to control operation of a motor. In accordance with the control input, the controller controls a corresponding flow of current through each of multiple windings of the motor. According to one implementation, the controller balances positive demagnetization and negative demagnetization of each of the multiple windings in a respective control cycle.
