Abstract
A limited large angle dynamoelectric machine generates a constant torque over an arc greater than 180 degrees without discontinuity and zero cogging. At any given location of the rotor, the flux path of the machine only crosses the stator coil at a single location. This results in the elimination of any type of commutation of the stator coil.
