A single phase motor drive circuit for driving a single phase motor, comprising: a timer unit 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 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 for receiving an input signal 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 method, an assembly and a cooling system includes the single phase motor driver circuit.
