Patent abstract
The efficiency of an induction motor is improved while suppressing the generation of magnetic flux saturation of a rotor core. In an induction motor, “a magnetic path width of a rotor” which is the product of a circumferential width of a rotor tooth formed in the rotor and the number of rotor teeth is equal to or larger than “a magnetic path width of a stator” which is the product of a circumferential width of a stator tooth formed in the stator and the number of stator teeth.
