Abstract
A two-phase bipolar 3.6° step motor is described in which the stator winding assembly has eight stator poles organized into decoupled phase groups with two distinct angular pole separations, 14.4°×[(4n±1)/4] between poles of the same group, and 14.4°×[(4m±1)/2] between adjacent poles of different groups, where n and m are positive whole numbers. Three stator teeth on each stator pole have a stator tooth pitch of 13.2° to minimize detent torque for smoother, more accurate stepping. A rotor has alternating magnetic north and south rotor teeth around a circumference thereof with a 14.4° rotor tooth pitch angle. The stator poles are wound with electromagnetic coil windings that can be driven in a series of phases to magnetically interact with the rotor.
