Abstract
A synchronous motor includes a disc-shaped rotor, a one-piece stator, and a coil assembly including a core and a winding therearound. The stator is connected to one end of the core and includes a pair of legs, the ends of which extend along an arcuate length thereby to define stator pole faces spaced from and concentric with the axis of rotation of the rotor. The rotor is magnetized radially and presents a plurality of contiguous substantially equally sized magnetic poles of alternating polarity at an air gap. The magnetic poles are of an angular length greater than the length of the stator pole faces. The motor is received by a molded casing providing means both for locating the stator pole faces and the rotor within the stator field at the air gap. The core provides an additional stator pole face in the magnetic field of the rotor and the winding of the motor is energized either by an A.C. or a D.C. source.
