The use of lower frequencies also provided the advantage of lower impedance losses, which are proportional to frequency.

DC motor is an open-loop system whereas servo motor is a closed-loop system. Others measure the back-EMF in the undriven coils to infer the rotor position, eliminating the need for separate Hall effect sensors. **To know the differences between an Induction and a Synchronous motor, read this article: Difference between Induction and Synchronous motor, **To know about other types of AC motor, read this article: Types of AC Motors, |DC Motor Working Principle, Construction and Diagram Explanation, |DC Generator Working Principle, Construction and Diagram Explanation. Synchronous motors are constructed of a stator, rotor and Synchronous motors are used in a wide range of applications. The other ends are tied together and connected to the third half bridge. The squirrel cage induction motor does not require a commutator, brushes, and slip rings. An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

Based on the winding type, there are two categories of rotors. The motor range is available from 10 HP to 500 HP at 2, 4, 6, 8 Poles. This is the basic working principle of the induction motor.
