Asynchronous electric motors are when compared to all rotating electric motors in manufacturing, which is used more in the industrial sector. Both stator and rotor conduct alternating current. The current acting on the rotor is an induced current, this is because of a variable magnetic field in conjunction with the rotor winding. This variable magnetic field in relation to the rotor winding is caused by the difference in rotational speed of the rotor and the rotating magnetic field. That is why the electric motor induction terminology.
The induction motor can operate both as a motor and as a generator baldor ac motors, but the characteristics of the motor operating as generators are not appropriate and therefore is normally used as a motor. Unlike the DC motor, the induction motor has a uniform air gap. The rotor may have a squirrel cage or winding type fabrication. The stator coils are installed along the air gap so as to better benefit from the ferromagnetic material and thereby optimize the driving magneto force distribution, attenuating the torque created by the motor.
