The rotor of squirrel cage motors, electric motor, and the washing machine

摘要

This description relates to a rotor of a squirrel cage (100), an electric motor (1) and a washing machine.The rotor of a squirrel cage (100) includes a rotor core (110).A rod guide of a squirrel cage and a ring of short circuit of the squirrel cage (120); the rotor core (110) is provided with a groove of the rotor (111) that penetrates through aUperfu00edcie of end of the rotor core (110); the guide bar squirrel cage is fitted in the groove of the rotor (111); the ring of short circuit of the squirrel cage (120) is fitted into theThe surface of the rotor core (110) and is connected to the guide bar squirrel cage.In a time of ring of short circuit of the squirrel cage (120) in an axial direction of the rotor core (110) is noted as H.A minimum internal diameter of the ring of short circuit of the squirrel cage (120) is denoted as D1.A maximum outer diameter ring of short circuit of the squirrel cage (120) is denoted as D2, and 7 mm = H = 14 mm, 0.53 = D1 / D2 = 0.78.
