The Three-Phase Wound-Rotor Induction Motor consists of a 4-pole machine rated at 2 kW. Each phase of the stator winding is accessible via the connection module to allow wye or delta connections. The rotor is wye connected to four slip rings to give access to all windings, including neutral.

The winding dimensions permit the study of operation as a wound-rotor induction motor, a frequency converter, a phase-shifter, a position controller, a variable-coupling single-phase transformer, a three-phase transformer, and an asynchronous induction generator.

The machine also has three search coils permitting observation of the flux distribution at one pole of the stator, at one tooth, and at the full-pitch of the rotor.
