"Cleaning" an electric motor
Jun 08, 2017· The electric shop in my alma mater had a very complete motor shop. They could rewind anything from slot car motors to 10,000 HP propulsion motors. Their motor stator and armature cleaning operation was very simple: they used a steam cleaner with nonionic detergent followed by a bakeout, then a dip and another bake.

Induction motor Wikipedia
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrelcage type.
