A method of starting a brushless motor that includes a rotor, a stator having at least one phase winding, and a rotor-position sensor. The method involves exciting the winding and sensing a signal output by the sensor. If an edge of the signal is sensed during a first period, the winding is commutated in response to the edge. Otherwise, the method involves commutating the winding at the end of the first period, sensing the signal, and commutating the winding in response to a second of two edges of the signal sensed during a second period. Additionally, a control system that implements the method, and a motor assembly that incorporates the brushless motor and the control system.
A method of starting a brushless motor, the motor comprising a rotor, a stator having at least one phase winding, and a rotor-position sensor, the method comprising:
