| Abstract: | As for PM propulsion motor supplied by frequency converter, using what kind of current to produce max electromagnetic torque is very important for its design and control. With a twelve phases PM test motor as the subject investigated according to its structural features and running mode, a simulation system was established for time-stepping finite-element method (FEM), the electromagnetic torque of this motor operating under sine wave, square wave or trapezoidal wave current was calculated with step-time finite element method, and the power-angle curves of this motor under different currents were given. The result shows that the sine wave current can produce max electromagnetic torque under usual power angle range for this twelve phases PM propulsion motor with strong armature reaction. |
