Abstract
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 an waveform for energizing the motor, the waveform generator being adapted for receiving the timing signal and at least one configurable setting (Soff), and for generating the waveform based thereon; a configuration unit adapted for receiving a first input signal indicative of a desired motor speed and a second input signal (Vbat) indicative of the supply voltage, and for determining the configurable setting based on the input signals, and for providing the setting to the waveform generator to dynamically configure the waveform generator. A method of driving a single phase motor.
