Abstract: A rotor of a squirrel-cage induction motor is provided to solve a problem of a low starting torque and a high starting current of a conventional three-state induction motor, and an abnormal starting phenomenon of a double squirrel-cage motor. A rotator core is composed by laminating a plurality of metal plates(112) in which a plurality of rotator slots and second rotator slots are arranged alternately along the edge portion, so that the first and second rotator slots(114,116) are placed continuously along an axis direction respectively. A rotator conductor(120) generates torque by an interaction of an induced current and flux, and is provided to the first and the second rotator slots. An end ring composes a circuit by connecting to the both ends of the rotator conductor.
