20120249044 | INVERTER FOR DRIVING AN ELECTRIC MOTOR COMPRISING AN INTEGRATED REGULATOR - 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. | 10-04-2012 |

20140346985 | DRIVE INVERTER HAVING A TORQUE ERROR DETECTOR - An inverter, which drives an electric motor installed in a road vehicle, includes sensors, a storage apparatus, a power calculator, a torque calculator, a deviation calculator, and a torque corrector. The sensors measure at least one voltage and at least one current within the inverter. The storage apparatus records values measured during an electric revolution of the motor. Following the electric revolution, the power calculator calculates a mean electric power based on the recorded values. From the mean electric power and a rotational speed of the motor during the electric revolution, the torque calculator calculates a torque produced on an output shaft of the motor, The deviation calculator determines a deviation between the torque produced on the output shaft and a setpoint torque of the inverter. When an absolute value of the deviation is greater than a predetermined threshold, the torque corrector makes a torque correction. | 11-27-2014 |
20140361612 | DRIVE INVERTER HAVING AN ABNORMAL TORQUE INVERSION DETECTOR - An inverter, which drives an electric motor installed in a road vehicle, includes sensors, a storage apparatus, a power calculator, a difference calculator, and a torque corrector. The sensors measure a voltage and a current within the inverter. The storage apparatus records values measured during a mechanical revolution of the electric motor. Following an electric revolution, the power calculator calculates instantaneous electric powers and a mean electric power based on the recorded values. The difference calculator calculates a mean value of a difference based on the instantaneous electric powers and the mean electric power. The torque corrector corrects a torque ripple in a case in which the mean value of the difference is greater than a predetermined threshold. | 12-11-2014 |
