ABSTRACT:
A yoke assembly for a stator of a starter motor is disclosed including auxiliary poles and magnet springs, with each of auxiliary poles and each of the magnet springs taking the form of a subassembly. The subassembly, composed of each of the auxiliary poles preliminarily mounted on each of the magnet springs, is fixedly secured to an inner peripheral wall of a yoke. This allows the subassemblies to be easily assembled to the yoke in the same process as that in which a yoke assembly is assembled using the magnet springs in the absence of the auxiliary poles, providing assembling processes in common with an increase in mass production effect.
