A Repulsion Electric Motor is by definition a single phase motor which has a stator winding arranged for connection to the source of power and a rotor winding connected to a commutator. Brushes and commutators are short-circuited and are placed so that the magnetic axis of the rotor winding is inclined to the magnetic axis of the stator winding.

During a recent safety and industrial hygiene of a steel mill, I noticed that some electrical motors were not equipped with covers (junction boxes) over the electrical connections where the motor wiring connects with the facility wiring. The wiring connects outside of any house or junction box, and, when installed, is covered with electrical tape.
