Rotor for electric motor

Abstract

Abstract PURPOSE:To improve fabricability by holding a yoke and a divided cylindrical magnet with an interposed ring spacer between upper and lower balance weights used also for presser boards, fastening these parts into an integral body and thereafter encasing said integral body in a reinforcing member tube. CONSTITUTION:A divided cylindrical magnet 3 is arranged on the outer periphery of a yoke 2 to be combined with a motor rotating shaft. A ring spacer 5 composed of non-magnetic material is caused to lie between said magnet 3 and upper and lower balance weights used also for prsser boards 4, said parts are caulked into an integral body by a plurality of rivets 7 having passed through holes 6, 6' of the upper and lower balance weights used also for presser boards 4 and the yoke. Then, the outer peripheral portions of the cylindrical magnet 3 and balance weights used also for presser boards 4 are en cased in a reinforcing member tube 8.
