ABSTRACT:
A motor or generator of the direct current type includes a stator carrying permanent magnets that is rotatable between first and second operational positions. A rotor having a winding and cooperating with a commutator is rotatable in either direction. The orientation of the magnetic field with respect to the commutator, as determined by the position of the stator, establishes the direction of rotation. If the stator is off-center when the rotor winding is energized, the stator will move to one of its operational positions under the force of a reaction torque.
