Abstract

PURPOSE:To produce an asymmetric and multipolar magnet disc in one magnetizing operation by setting slots of different depths on the inner periphery of a magnetizing yoke, and by connecting in series a winding of each pole. CONSTITUTION:Poles 2A-2F are formed with equal intervals on the inside surface of a cylindrical magnetizing yoke 1. Deep slots 3 are formed on both sides of poles 2A, 2C, 2E, shallow slots 4 on both sides of 2B, 2D, 2F. In slots 3, 4 are stored windings 5A-5F respectively and successively connected in series. Windings 5A, 5C, 5E and windigs 5B, 5D, 5F are contrary in their directions of windings. Within a magnetizing yoke 1 is placed a magnet disc 6 not yet magnetized, and each pole is directed against the periphery surface of the disc 6, when direct current 7 is instantaneously applied on winding terminals 8A, 8B for magnetizing. The different position of each winding due to the slot depths produces strong magnetic poles on the periphery part of the magnet disc 6 facing poles 2B, 2D, 2F and weak magnetic poles of inverse magnetic property on the part facing poles 2A, 2C, 2D. Thus, an asymmetric and multipolar magnet disc is completed.
