Abstract
In a method of controlling speed of a brushless, direct current (BLDC) motor based on dwell, an indication of a desired speed of the BLDC motor is received. A dwell is determined based on a magnitude of a voltage corresponding to the indication of the desired speed. A pulse-width modulation (PWM) pulse having a pulse length corresponding to the determined dwell is applied to a stator of the BLDC motor to adjust a rotational speed of a rotor of the BLDC motor to the desired speed.
