Document Type and Number:
Japanese Patent JP6720032
Kind Code:
B2
Abstract:
If B, L, M, N, and X denote natural numbers, S denotes the number of slots (15), P denotes the number of magnetic poles of a magnet (9), and A denotes the smallest value among values of L that satisfy X = 90(2L-1)/{(360/S)×(P/2)}, the number S of slots (15), the number P of magnetic poles, and an electrical angle θ between a second Hall IC (50b) and a third Hall IC (50c) are set such that S = 2N, P = S±2, θ = 90(2B-1), and B < A. At least one among the second Hall IC (50b) and the third Hall IC (50c) is disposed at a position offset from the circumferential center of the slots (15), and a notch part that is capable of receiving any one among the second Hall IC (50b) and the third Hall IC (50c) is formed in at least one tooth part (13).
