A stepping motor having a printed circuit rotor including a first printed circuit on one side of the rotor formed in a plurality of spiral coil windings, and a second printed circuit on the other side of the rotor formed in an equal number of like coil windings, the coil windings on one side being 90 degrees out of phase with those on the opposite side. The motor also includes a slip-ring arrangement for delivering pulsed DC power alternately to the first and second printed circuits for driving the rotor in a step-wise manner.
