LINEAR MOTOR WITH PATTERNED MAGNET ARRAYS

Title:

LINEAR MOTOR WITH PATTERNED MAGNET ARRAYS

Document Type and Number:

WIPO Patent Application WO/2010/027740

Kind Code:

A8

Abstract:

An armature for a linear motor has permanent magnets arranged in a Halbach - like manner which form alternating magnetic poles (542, 546). The magnetisation directions of adjacent magnets (502a1 - 502a4 or 502b1 - 502b4) forming one pole (542 or 546) differ by a first angle; the magnetisation directions of those two adjacent magnets (502a4, 502b1) which represent the boundary between two adjacent magnetic poles (542, 546) differ by a second angle which is different from the first angle.
