TORQUE OSCILLATIONS IN TRACTION DRIVES WITH CURRENT-FED ASYNCHRONOUS MACHINES

An asynchronous machine supplied by an inverter with nonsinusoidal currents generates an internal torque, which is the superimposition of a constant torque with an oscillating torque is discussed. If the torque harmonics coincide with the mechanical resonances of the mechanical power transmission, a pulse-current modulation is needed in order to avoid problems. At a laboratory test set-up measurements have been performed. Some of the results are presented.
