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.
Claims18
An apparatus comprising:
- a controller operative to:
- receive control input;
- in accordance with the control input, control current through each of multiple windings of a motor;
- and
- balance positive demagnetization and negative demagnetization of at least one winding of the multiple windings in a respective control cycle of controlling the current.
A method comprising:
- receiving control input;
- in accordance with the control input, controlling current through each of multiple windings of a motor;
- and
- balancing positive demagnetization and negative demagnetization of at least one winding of the multiple windings in a respective control cycle of controlling the current.
Computer-readable storage media having instructions stored thereon, the instructions, when executed by computer processor hardware, cause the computer processor hardware to:
- receive control input;
- in accordance with the control input, control current through each of multiple windings of a motor;
- and
- balance positive demagnetization and negative demagnetization of at least one of the multiple windings in a respective control cycle of controlling the current.
