Abstract
A stop-detection method intended for a multi-phase synchronous geared motor that is controlled in a stepping mode, which measures the sum of the currents circulating in each of the N phases of the geared motor. In the method the stop detection threshold is calculated in relation to the change in the sum of the currents.
