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
