Abstract:
To provide an indication motor rotor capable of improving motor performance by concentrating portions under magnetic saturation conditions of rotor teeth. The rotor of an induction motor of this invention may include slots formed approximately in the shape of a T. The slots may be formed so that top slots are arranged on an outer peripheral portion of a rotor core, and bottom slots are arranged on an inner side of the top slots. The width in the circumferential direction of the top slot is wider than the width in the circumferential direction of the bottom slot, and the width in the circumferential direction of a rotor tooth between adjacent top slots is narrower than the width in the circumferential direction of the rotor tooth between adjacent bottom slots.
