Rotor End Ring For Motor

摘要

The subject innovation, the large number of core plates are provided at the respective side end portions of the rotor formed of stacked and fixed to both ends of the rotor, and as relates to the induction end ring of the motor rotor for being molded by die-casting, the region corresponding to the sprue of the die casting mold in that the peripheral portion escape tree predetermined depression depth is formed in the formed features. In this way, when inserting the rotation shaft in the rotor core can tailor the exact insertion height, to remove the scratches that are generated around the projections it is possible to improve the characteristics of the motor.
