SQUIRREL CAGE ROTOR OF AN INDUCTION MOTOR, CAPABLE OF PREVENTING THE REDUCTION OF STARTING CHARACTERISTIC OF AN INDUCTION MOTOR BY USING A ROTATOR SLOT STRUCTURE WHICH HAS DIFFERENT SLOT SHAPE

摘要

PURPOSE: A squirrel cage rotor of an induction motor is provided to control a second resistance value by controlling the amount of the aluminum used for a rotor.;CONSTITUTION: A rotor core(121) is formed into a first core and a second core which are laminated by turns. The first core is formed by laminating a plurality of steel sheets with a plurality of slots(125). The slots are formed along an axial direction in the edge of a cylindrical steel sheet. The second core is formed by laminating a plurality of steel sheets which have a plurality of slots which has a different slot from a slot of the first core. The slots are formed in the axial direction in the edge of the cylindrical steel sheet. A rotary shaft(130) is combined in the central part of the rotor core. A short-circuit ring(124) is arranged in both end parts of the rotor core.;COPYRIGHT KIPO 2010
