Abstract:
A method for detecting stall of a multiphase motor operated in a sinusoidal micro-stepped mode. The method comprises: a) measuring at least one phase current and/or measuring the sum of all phase currents at regular time intervals synchronous with the micro-steps, b) calculating the difference between the measured phase current at a first moment and the measured phase current of the same phase at a previous moment and/or the difference between the measured sum of all phase currents at a first moment and the measured sum of all phase currents at a previous synchronous moment, c) analyzing the series of obtained current differences so as to generate a stall detection signal.
