Abstract

PURPOSE: To obtain a rotor of a high conversion efficiency and a highly accurate dimension by a simplified method in which a nock-out pin whose tip portion has differently staged form is attached to molds to form integrally the constitutional parts of rotor by pouring a high polymer.
CONSTITUTION: The three portions of each of the circumferential side 8a and both ends 8b of the cylindrical rotor magnet 8 of a rare earth intermetallic compound magnet material are positioned by the convexities 12 and 13 of the female mold 5 and the positioning part 4 of the male mold 1 and then a high polymer is poured from the gate 2 to form integrally the rotor centers 15 and 16, the rotor collar 17, and the rotor-coupling portion 18. Then, the high polymer in the gate 2 is drawn out, the male mold 1 is moved upwards, and the knock-out pin 11 (tip portion has the differntly staged portion 10 and part of the bottom 10a of the differently staged portion 10 is superposed over the rotor magnet 8 flatly and at the same time supports the rotor-coupling portion 18) provided to the female mold 5 is projected upwards to take out the rotor 14.
