Abstract

PURPOSE:To keep strength and sealing property, by a method wherein yokes and permanent magnets are arranged in the cylinder of an outer peripheral cover while a gap is filled with a diecast material, resin or the like. CONSTITUTION:A rotor is constituted of divided arced permanent magnets, arranged around a laminated iron core 1 provided with a hole 6 penetrated axially, and a cylindrical protecting cover 3, covering the outer periphery of the permanent magnets. In order to prevent the permanent magnets 2 from deviating axially, one end of the permanent magnets is pushed by an iron core abutting part 1a while the other end is stopped by a collar 5. Thereafter, diecast material is filled through a slot 6 by diecasting to obtain an integrated structure. In this case, the same structure may be obtained by filling resin instead of the metallic diecast material, serving as a connecting member connecting the iron core to the collar through the hole 6 of the iron core and the slot of the collar 5.
