摘要：
Finite element analysis is used to directly compute torques and currents of an induction motor, without need for any equivalent circuit. The ac voltages are applied by means of 0D and 1D finite elements, and the fields and related parameters are computed by nonlinear transient FEA with adaptive time stepping. Equations;Ire derived that allow balanced polyphase motors to be analyzed at any speed without rotating the rotor Finite elements. Computed torques and currents of a typical polyphase motor with closed rotor bars are shown to agree quite well with measurements.
