Abstract
A plurality of single phase arrays have disc-type rotors and stators and are supported in tandem with adjacent arrays separated by magnetic partitions. Polyphase operation is achieved by time shifting the dynamic magnetic field induced within the N.sup.th array with respect to the dynamic magnetic field induced within the (N-1).sup.st array. A static magnetic field structure provides optimum power factor with respect to maximum average torque. A disc structure is provided which realizes maximum available starting torque regardless of rotor position.
