Abstract
Stall detection apparatus for an electric motor controller has an input for receiving a drive error flag indicating if the controller is unable to achieve the required motor velocity and an input for receiving a signal in order to measure, directly or indirectly, the actual motor velocity. The actual motor velocity is determined in order to indicate whether the motor is stationary and, only if so, a stall signal is outputted in order to indicate that said motor has stalled.
