出す。Next, the operation will be described. First, a power supply is applied to the winding 11 and a current flows, and a magnetic field is generated in a gap between the stator 8 and the rotor 4. An electromagnetic force is generated by a current induced in the conductor 6 of the rotor 4 by the excited magnetic field, and gives a rotational force to the shaft 1. When a current flows through the winding 11 and the conductor 6, heat is generated by a loss such as a resistance loss. The heat is cooled by ventilation, and air is sucked into the induction motor from the air hole of the bracket 3 and is discharged from the air hole of the frame 9 through the winding 11 by the cast blade 7 of the rotor 4.
