A stepper motor is disclosed which is comprised of planar elements. The motor comprises a disc-shaped rotor which includes a multipolar permanent magnet and generally planar stator coils mounted on opposite sides of the rotor. In order to provide a stepper motor which is efficient and is also relatively thin in the axial direction, generally planar pole plates having radially extending teeth are used to define the magnetic poles of the stator.
