Abstract: A method of controlling a sensorless motor (32). The method contains the steps of determining a current speed of the motor (32); selectively using a first method, a second method, or a third method to determine a position of a rotor of the motor (32), depending on the current speed of the motor (32); and transmitting a drive signal to the motor (32) based on the determined position of the rotor. A sensorless motor assembly is also disclosed. According to the method, multiple rotor position detection methods are provided to the sensorless motor (32) which cover a full speed range of the motor (32).
