    摘要: A squirrel cage induction motor includes: a stator core (11); a plurality of stator slots (12) radially disposed in a circumferential direction of the stator core (11) with predetermined intervals; a plurality of stator windings (13) housed in the stator slots respectively; a rotor core (21); a plurality of rotor slots (22) radially disposed in a circumferential direction of the rotor core (22) with predetermined intervals; a plurality of rotor conductors (23) housed in the rotor slots (22) respectively. The stator windings (13) and the rotor conductors (23) includes electrically conductive materials mainly composed of copper. An area ratio of a total area of the stator slots (12) to a total area of the rotor slots (22) is not smaller than 2.7 and not greater than 8.0 to provide compatibility between the starting characteristic (starting torque) and the steady characteristic (for a high efficiency) can be provided.
