ABSTRACT OF THE DISCLOSURE A high performance stepper motor suitable for construction in linear or rotary form and useful, for example, in high speed printers or typewriters comprises a stator having a plurality of pole positions. Each of the pole positions includes a plurality of stator elements on opposite sides of air gap with nonmagnetic material located in the spaces between the extremities of the stator elements. A plurality of windings adapted to be connected to a multiphased drive source are associated with the stator on only one side of the air gap at the various pole positions. Passive motive means such as a rotor or a slider includes a plurality of motive elements and is located within and confined to the air gap of the stator. The motive elements comprise magnetic material and have extremities juxtaposed to the extremities of the stator elements on both sides of the air gap so as to establish flux paths transverse to the air gap and movement of the motive means relative to the stator means with the resulting force acting on the motive elements at both sides of the air gap. The motive means comprises nonmagnetic discontinuities in the magnetic material extending transverse to the direction of movement of the motive means so as to reduce flux leakage in the direction of movement while simultaneously reducing the mass of the motive means.
