Benefits of| AC Induction Motors

An induction electric motor or asynchronous motor can be an AC electric engine in which the electric energy in the rotor had a need to create torque is obtained by electromagnetic induction from the magnetic field of the stator winding. … An induction motor's rotor could be either wound type or squirrel-cage type.
Great things about AC Induction Motors are:

Induction motors are simple and rugged in building. They are better quality and can operate in virtually any environmental condition
Induction motors are cheaper in expense because of simple rotor construction, lack of brushes, commutators, and slip rings
They are free of maintenance motors unlike dc motors due to the absence of brushes, commutators and slip rings
Induction motors could be operated in polluted and explosive conditions as they don't have brushes that may cause sparks
AC Induction motors are Asynchronous Devices and therefore the rotor does not switch at the specific same speed because the stator's rotating magnetic field. Some difference in the rotor and stator rate is necessary to be able to create the induction into the rotor. The difference between your two is called the slip. Slip should be kept within an optimal range to ensure that the motor to use effectively. Roboteq AC Induction controllers could be configured to operate in another of three modes:

Scallar (or Volts per Hertz): an Open up loop mode in which a command causes a simultaneous, ac motor fixed-ratio Frequency and Voltage alter.
Controlled Slip: a Closed Loop speed where voltage and frequency are controlled in order to keep slip within a narrow range while working at a preferred speed.
Field Oriented Control (Vector Drive): a Closed Loop Velocity and Torque control that works by optimizing the rotating field of the stator vs. this of the induced field in the rotor.
