Abstract
A rotary drive system having a voltage source and an electric motor. The motor has a stator with independent phases and a rotor, an inverter designed to connect each phase to the voltage source in order to generate phase currents, and a device for controlling the inverter. The control device includes a unit for determining whether the fundamental frequency of the phase currents is lower than a frequency threshold equal to, at the most, 100 Hz, and a unit for generating a command, configured such that, when the fundamental frequency is determine as being lower than the frequency threshold, the command causes the appearance of a homopolar component in the phase currents.
