ABSTRACT:
A pulse motor comprising a rotor having at least two magnetization axes extending parallel to a shaft of the rotor and angularly spaced apart at a uniform interval, the direction of magnetization of each magnetization axis being opposite to that of the adjacent magnetization axis; a pair of upper stators extending above the rotor and defining two upper gaps between them, said upper gaps being adapted to face respective unlike polarity poles on the upper side of the rotor; a pair of lower stators extending below the rotor and defining two lower gaps between them, said lower gaps being adapted to face respective unlike polarity poles on the lower side of the rotor; and at least one drive coil for magnetizing the upper and lower pair stators alternately to opposite polarities such that the polarity of one of the upper pair stators and one of the lower pair stators is opposite to the polarity of the other upper and lower stators.
