The high starting currents can cause possible unforeseen events, due to the fact that they need dimensioning of cables with relatively larger diameters than necessary. It is also feasible for power factor drops to occur, a factor that must be controlled by the utility, which may result in an increase in power bills. The induction motors with squirrel cage rotor are basically made up of two parts. The stator, which consists of a magnetic circuit of the electric motor, a large part of the grooved type, https://www.mrosupply.com/motors/ac-motors/general-purpose-motors/2525868_11463800_leeson/ in which the coils are installed, which by means of a suitable connection will generate the rotating magnetic field.
Thus, the rotor consists of a winding consisting of bars, which may be of materials such as copper or aluminum, shorted at the ends. The current in the rotor circuit will be induced by the action of the rotating field of the stator. The induction motor at the moment of actuation indicates that the magnetic field produced in the rotor circuit will follow the rotating field of the stator. If the motor is energized, it will be able to operate as a transformer with the secondary being short-circuited, requiring a much larger current than the nominal current, reaching about ten times its value.
