SQUIRREL CAGE ROTOR FOR AN ASYNCHRONOUS INDUCTION MOTOR

摘要

The novel squirrel-cage rotor should enable a power output of the motor of more than 1 MW even at rotation speeds of more than 10,000 rpm. To this end, the conductor bars ( 4 ) of the squirrel cage are soldered into slots ( 8, 9 ) arranged on the periphery of the massive rotor core ( 3 ) across their entire length, and the conductor bars are arranged to be flush with the surface ( 13 ) of the rotor core ( 3 ).
