摘要： When a pitch between centers of two adjacent magnetic pole portions disposed on an armature is defined as τs, the length W of permanent magnets disposed in the middle is equal to the pitch τs (W=τs). The length of each of the two end permanent magnets respectively disposed at either end of a permanent magnet magnetic pole row is denoted by W1. A ratio w1/W of the length W1 to the length W is defined as 0.43

The first and second direct drive shafts each have a yoke mounting portion and paired supported portions at both axial ends of the yoke mounting portion. The first and second direct drive shafts are so shaped that the cross section of the yoke mounting portion orthogonal to the axial direction is smaller than that of the supported portions. Each of the electromagnetic steel plates is made up of first and second divided electromagnetic steel plate pieces of the same shape.
