The most used winding type for medium-size induction motors is a double layer winding with pitched winding step, for example pitched for two stator slots (Fig. 2). Significant advantage of the aforementioned winding is a smaller mass of inserted copper because of shortest winding-ends.
What are the two windings of an induction motor?
Except for shaded pole motor, the asynchronous motor has two stator windings namely the main winding and the auxiliary winding. These two windings are placed in space quadrature to each other.
Where is induction motor used?
AC induction motors are the most common electric motors in the world. These simple, reliable and economical motors are found in refrigerators, washing machines and furnaces, as well as conveyors, pumps, winders, wind tunnels and other industrial equipment.
What is induction motor principle?
Working Principle of Induction Motor
The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.
What 3 things are needed for an induction motor to work?
A 3-phase induction motor includes two essential components namely the stator & the rotor. In this motor, the stationary part is the stator whereas the rotating part is the rotor. In this motor, the load is connected to the shaft. Three-phase armature winding can be wound over the stator.
What is the difference between induction motor and normal motor?
Difference between Three Phase Induction Motor and Synchronous Motor. A three-phase synchronous motor is a doubly excited machine, whereas an induction motor is a single excited machine. The armature winding of the synchronous motor is energized from an AC source and its field winding from a DC source.
Which motor is used in table fan?
Usually, table fans contain single phase induction motor. This is the primary component of these electric fans. The fan’s capacitor is used for giving the starting torque to the motor that allows the fan to start and run.
