PURPOSE:To improve the magnetizing properties of a magnet without lowering the productivity of a rotor by disposing a magnetizer for magnetizing a magnet blank on the outer circumference of an assembled rotor assembly and inserting magnetizing coils for magnetizing the magnet blank into each radial clearance. CONSTITUTION:Notched holes are formed in response to the radial clearances 30 of the inner circumferential end sections of each magnet blank 20 of a magnet assembly 10 and a shaft 16 to end plates 12, coils 18 for magnetization with yoke members are inserted through the notched holes, each coil end section is connected mutually, and all magnet blanks 20 are simultaneously connected detachably. Magnetizers are arranged on the outer circumference of a rotor, and the magnetizers and the coils 18 for magnetization are bonded and the magnet blanks are magnetized simultaneously from the outer circumferential side and inner circumferential side of the rotor. Magnetization is completed, the magnetizers on the outer circumferential side and each yoke 21 and the coils 18 are extracted from the outside, thus manufacturing the radial type rotor with uniformly magnetized magnet 20. |
