ABSTRACT:
A linear stepping motor comprises a stationary member, a movable member, an attraction magnetic pole and a guiding magnetic pole. The movable member has four pole pieces each having a plurality of teeth facing those of the stationary member. The attraction magnetic pole maintains the movable member floated by a magnetic coil providing an attractive force. The guiding magnetic pole has four coils on the four pole pieces, and causes the movable member to move by consecutive and selective energization of the four coils.
