Abstract
A method of controlling a brushless motor. The method includes measuring a temperature of the motor, adjusting a control value in the event that the measured temperature is lower than a threshold, and exciting a winding of the motor. The control value is then used to define an attribute of excitation, and the adjustment to the control value reduces the input power of the motor.
