Abstract
PURPOSE: To simply and cheaply manufacture a magnet rotor of radial anisotropy, by drawing a plastic permanent magnet material having an easy magnetization axis in the direction of the thickness.
CONSTITUTION: A plastic permanent magnet material sheet 1 having an easy magnetization axis in the direction of the thickness is drawn by a die 2 and a punch 3 so that the annular part 5 of a cup-shaped piece 4 has an easy magnetization axis in the radial direction and the flange 6 and flat bottom 7 of the piece 4 have easy magnetization axes in the axial direction. The cup-shaped piece 4 is inserted into a punching die 10 having a die hole 9 of diameter almost equal to the inside diameter of the housing section 8 of the annular part 5 of the piece 4. A punch 11 of diameter slightly smaller than that of the die hole 9 is pressed down on the flat bottom 7 of the cup-shaped piece 4. The flange 6 is cut off. This results in providing a rotor magnet 12 having an easy magnetization axis in the radial direction.
