Problems solved by technology
[0002] It is pointed out in related technologies that the quality of the balance washer of the squirrel-cage motor cannot be made too large. When the dynamic unbalance of the rotor is large, filling up the balance nails cannot meet the requirements of the dynamic unbalance, and increasing the balance nails may Can cause interference with squirrel-cage motor components
In addition, the number of balancing washers required for balancing is large, and the balancing efficiency is low.

The invention discloses a mouse cage type motor and a rotor used for the same. The rotor comprises a rotor iron core, an end ring, at least one balance nail and at least one balance block, the end ring is arranged at the end of the rotor iron core, the balance nails are arranged on one side, away from the rotor iron core, of the end ring, each balance block sleeves the corresponding balance nail, the balance blocks correspond to the balance nails in a one-to-one manner, outer contour of each balance block is non-circular, at least one stop nail is arranged on each of the balance blocks and the end ring, at least one stop hole is formed in the other of the balance blocks and the end ring, and the stop holes are matched with the stop nails to prevent the balance blocks from rotating around the balance nails. According to the rotor, mass of the balance blocks can be bigger, and the problem that conventional balance nails are insufficient in height is solved. In addition, the balance blocks after being mounted on the balance nails can be effectively prevented from rotating to exceed the rotor iron core to generate interference with other parts of the mouse cage type motor.
Description
technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a rotor for a squirrel-cage motor and a squirrel-cage motor with the same. Background technique [0002] It is pointed out in related technologies that the quality of the balance washer of the squirrel-cage motor cannot be made too large. When the dynamic unbalance of the rotor is large, filling up the balance nails cannot meet the requirements of the dynamic unbalance, and increasing the balance nails may Can cause interference of squirrel cage motor parts. In addition, the number of balancing washers required for balancing is large, and the balancing efficiency is low. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, it is an object of the invention to propose a rotor for a squirrel-cage electric machine whose counterweight mass can be increased. [0004] An...
