ABSTRACT:
The present invention is a one-phase stepping motor having a predetermined direction of rotation. The motor comprises a rotor having 2p permanently magnetized poles on its outer surface. The rotor is surrounded by a coil, which when energized forms the main stator poles. Auxiliary pole arms extend into the space between the coil and the rotor.
The rotor and coil are stored in a two-part housing which magnetically isolates the motor. The auxiliary pole arms extend inward from the top and bottom surfaces of the housing and are formed integrally therewith.
The arrangement of the auxiliary pole arms serves to determine the direction of rotation of the rotor. Illustratively, the auxiliary pole arms are divided into groups. Within each group, the auxiliary pole arms are at a distance from the rotor that decreases gradually or in stages in the direction of rotation of the rotor.
This one-phase stepping motor is especially suitable for driving counting mechanisms in electricity meters.
