Abstract (en)
[origin: WO2016012329A1] The invention relates to an electric stepper motor having at least two electric phases, including a stator (2) having a plurality of magnetic stator poles (P) for each electric phase. The stator includes a magnetic armature (6) comprising a plurality of coil cores (14) and a plurality of coils (8, 9) for each electric phase, which coils are mounted on the coil cores. Each coil defines one of said magnetic poles of the stator. The plurality of coils of each electric phase are formed from at least two conductive wires (11, 21, 31, 41) which are connected in parallel. One or more coils includes one of the conductive wires and one or more other coils comprise the other one of said conductive wires.
