The paper presents a two-dimension (2-D), direct-coupled circuit-field-motion, time-stepping, finite element analysis for a wound-rotor induction motor with time-stepping method. With the accurate torque computation, the start up transient of the induction motor is investigated. The field results both at no load and at rated load are obtained. The steady and transient performance of varied mechanical load is studied. The slip ring induction analysis results can be used for website design for green energy teaching.
