Title:
PERMANENT MAGNET FIELD ROTOR STRUCTURE
Document Type and Number:
Japanese Patent JPS5959054
Kind Code:
A
Abstract:
PURPOSE:To simplify the structure by press-fitting a pole forming part made of a permanent magnet and a yoke to the end of securing a rotational shaft and integrating them. CONSTITUTION:A rotor is composed of permanent magnets 1 and yokes 2. The permanent magnets 1 and the yokes 2 are alternately radially disposed so that the outer peripheral surfaces projected from the yokes 2 from pole surfaces. Part 3 of the yoke 2 is projected to cover the outer peripheral surface of the magnet 1, and these members are integrated by mutually securing the yokes 2. Terminal boards 4, 5 are disposed on both end surfaces of the members. The deep units 7, 8 of the boards 4, 5 are engaged with the end of the assembly of the magnets 1 and the yokes 2, thereby eliminating the fastening means such as bolts or the like.
