A single phase motor drive circuit (600) for driving a single phase motor (690), comprising: a timer unit (701) for receiving a sensor signal indicative of an angular position of a rotor, and for providing a timing signal in phase with the sensor signal; a waveform generator (602) for generating a waveform for energizing the motor, the waveform generator being adapted for receiving the timing signal and a configurable setting, and for generating the waveform based thereon; a configuration unit (603) for receiving an input signal (691) indicative of a desired motor speed, the configuration unit being adapted for generating the configurable setting as a function of the input signal, and for providing the setting to the waveform generator to dynamically configure the waveform generator. A assembly and a cooling system comprising the single phase motor driver circuit (600). A method of driving a single phase motor (690). |
