Abstract
A method of controlling a brushless motor that includes sensing a temperature and using the sensed temperature to define a current limit. A lower current limit is then defined for a lower sensed temperature. A winding of the motor is sequentially energized and de-energized, with the winding being de-energized when current in the winding exceeds the defined current limit.
