Stall detection apparatus for an electric motor controller has an input 12 for receiving a drive error flag indicating if the controller is unable to achieve the required motor velocity and an input 14 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 10 is stationary and, only if so, a stall signal 52 is outputted in order to indicate that said motor has stalled. Preferably the use of a discriminator 20 is used for determining the actual velocity. Preferably the motorized vehicle is a wheelchair. |
