Abstract

This new design method is aimed at the disadvantages that the energy cannot feed back into the power network with a non-electric dynamometer, and a DC dynamometer is influenced by a commutator, a method of dynamometer design, based on direct torque control, is introduced. The dynamometer has the characteristic of constant torque when the rotation's speed has a downward rating value, and it has the characteristic of constant power when the rotation's speed has an upward rating value. The system experiment shows that direct torque control can effectively reduce torque pulsation and obtain satisfactory dynamic performances, and that the torque can be controlled accurately and quickly. The AC dynamometer has better performance and it has important application value.
