Abstract
A driving inverter for a multi-phase electric motor includes an alternating current (AC) generator, at least one AC sensor, a power supply line, a current sensor, an input, and a controller. The AC delivers current to a terminal block that is connectable to the phases of the electric motor. The at least one AC sensor is arranged on a certain phase or certain phases powering the electric motor. The current sensor is arranged on the power supply line and senses a current thereon. The input receives information that includes a torque demand setpoint and at least one limit current value of a power source. The controller drives phase currents of the electric motor according to the torque demand setpoint and by keeping the current of the power supply line at an acceptable value according to the at least one limit current value of the power source. With the arrangement of the driving inverter, a maximum current can always be imposed on the power source with no risk of degrading it.
