Abstract

See full text

A linear and rotary electromagnetic device particularly adapted as a linear and rotary stepper or stepper motor. A cylindrical movable member or armature is provided which is mounted for both axial movement and for angular movement about its axis. The armature member has teeth on its surface formed in both axial rows and in circumferential alignment or rows. Stator means having poles with windings associated with the poles is provided, the stator means having a central opening in which the movable armature member is mounted for axial and angular movement. By energizing certain angularly spaced windings, the movable armature member may be caused to rotate. By energizing axially spaced windings, the movable member of armature can be caused to move axially. Simultaneous angular and axial movement is achieved by energizing appropriate windings.
