The first and second magnetic pole piece arrays are disposed with a predetermined phase difference therebetween. The first magnetic pole piece array includes first magnetic pole pieces disposed at a second pitch in an array and each having a length enough to face at least two adjacent magnets in the magnet array. The second magnetic pole piece array is configured similarly to the first magnetic pole piece array. One of the first and second magnetic pole piece arrays and the magnet array is relatively moved to the other at a predetermined speed.

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
