(under the class definition) Subject matter in which means are provided for controlling the physical structure (e.g., shifting commutator brushes, pole pieces or other magnetic structure, coil position, etc., relative to other structure) of an electric motor and for also controlling an electric circuit connected to the motor for affecting the supply of energy to, or the operation of the motor.
(1) Note. Rotary movement of a rotary electric motor resulting from electric energization of the motor is not bias for classification herein. However, axial movement of the rotor other than by the magnetic force of the motor is structure control included herein. [figure]
