ABSTRACT:
An over-loading detection system periodically samples a motor operating parameter, e.g. a revolution speed and an output torque at a predetermined relatively short sampling period. Based on the sampled motor operating parameter, a ratio of the output torque and a predetermined over-load rating torque is derived and stored. Over-load detection is performed with respect to a plurality of sampled ratios of the output torque and the over-load rating torque by deriving a running average and comparing the derived running average value with a predetermined threshold.
