ABSTRACT:
A device limits the power supply current for a direct current electric motor with electronic switching. The stator of the motor comprises several windings angularly displaced and successively energized by an electronic switching device to create an electric field. The device is arranged so as to establish a limitation of the current in accordance with an operating parameter of the motor according to a relation which takes the variation of the load into account according to the parameter and which only authorizes a slightly higher current than that necessary for normal operation.
