It should be noted that when being intervally distributed with multiple N magnetic poles and multiple S magnetic poles on every layer of magnet assembly 10, N magnetic poles Equal with the magnet pole widths of S magnetic poles, the magnet pole widths of each N magnetic poles or S magnetic poles can be equal to magnet assembly 10 along moving component The ratio between total number p of width D and N magnetic poles and S magnetic poles on moving direction, i.e. s=D/p；It is spaced when on every layer of magnet assembly 10 When multiple N magnetic poles are distributed with, the magnet pole widths of each N magnetic poles may approximately equal to magnet assembly 10 along the moving direction of moving component Width D and N magnetic poles and the first white space the ratio between total number p, i.e. s=D/p；It is spaced apart when on every layer of magnet assembly 10 When having multiple S magnetic poles, the magnet pole widths of S magnetic poles and white space are equal, and the magnet pole widths of each S magnetic poles may approximately equal to magnetic group Part 10 is along the ratio between total number p of the width D on the moving direction of moving component and S magnetic poles and the second white space, i.e. s=D/p.
That is, pre-determined distance, i.e. d=D/p/x can be also determined according to the following formula.
Specifically, by taking the number of plies x=2 of magnet assembly 10 as an example, the corresponding magnetic pole of upper and lower two layers of magnet assembly staggers s/ 2, it is assumed that multiple N magnetic poles and multiple S magnetic poles are intervally distributed with every layer of magnet assembly 10, the width D of each magnet assembly 10 is The total number p of 15mm, N magnetic pole and S magnetic poles be 15, then pre-determined distance can obtain d=D/p/x=15/15/2=0.5mm, i.e., on The correspondence magnetic pole of lower two layers of magnet assembly staggers 0.5mm.More specifically, as shown in figures 8-13, lower floor magnet assembly 10B is opposite In upper strata, magnet assembly 10A staggers s/2 such as 0.5mm, and on upper strata, the corresponding Hall detection components 20A of magnet assembly 10A are located at During the initial position of N magnetic poles, the corresponding Hall detection components 20B of lower floor magnet assembly 10B are located at 1/2 position of N magnetic poles, phase Ying Di, when opening direction of the x layers of magnet assembly 10 into Fig. 3 shown in arrow moves, the corresponding Halls of lower floor magnet assembly 10B The inductive signal of detection components 20B outputs lags 90 ° relative to the corresponding Hall detection components 20A of upper strata magnet assembly 10B.
