End ring structure for rotor bar fixing of motor

摘要

The present invention relates to an end ring structure for fixing a rotor bar of an electric motor, and more particularly, to an end ring structure for fixing a rotor bar of an electric motor, which comprises an outer side portion 1 having a top-type inner slot 1a formed by an annular inner rim portion, The inner side 2 of the inner side 2 and the inner side 2 of the outer side 1 are formed symmetrically with the slot 1a and formed with the outer side slot 2a, Since the rotor is provided with the end ring formed of the seating groove 3, which is a rectangular groove formed by connecting the rotor 1 a and the rotor 1 a, the function of the end ring for connecting the rotor bar fixed to the slot groove formed in the rotor, The function of the shrink link provided for slidably separating the rotor bar due to the centrifugal force generated when the end ring and the shrink ring are installed is performed by the single end piece and the number of operations for installing the end ring and the shrink ring is reduced.
