ABSTRACT:
A stepper motor includes a rotor having a ring-shaped body having a circumference along which a plurality of magnetic poles of alternates. A plurality of stator members is arranged along and spaced from the circumference of the rotor. Each stator member has two limbs circumferentially spaced from each other by an angular range corresponding to an odd number of the magnetic poles of the rotor. A coil winding is formed around an end portion of each limb of each stator member and is substantially flush with the end face of the end portion to reduce and minimize magnetic loss. The stepper motor further includes a circuit board to which the coil windings are electrically connected whereby the phase switching sequences of the stator members and the windings is controlled.
