Document Type and Number:
Japanese Patent JP2000502240
Kind Code:
A
Abstract:
Disclosed is a method for manufacturing a rotor structure for a motor using a square shaft member and four magnet members and the structure produced thereby. The method comprises the steps of: (a) mounting to each of the lateral surface of the shaft the back surface of one of the four magnets thereby to form a single circumferential layer of magnets about the shaft, the four magnets being mounted such that: (i) a portion of the back surface of each of the four magnets extends past an edge of the shaft for at least a predetermined distance thereby to define about the circumference of the shaft a total of four overhanging areas; and (ii) one side surface of each of the four magnets abuts against an overhanging area; and (b) thereafter forming the single circumferential layer of the four magnets into a continuous circular contour centered on the axis of the shaft.
