Answer – AC motor needs cooling due to Eddy current loss. This eddy current starts flowing into the frame of the motor, due to which the motor starts heating up. So the motor is not too hot at this time. For this, we put a band on the AC motor and it will work well.
Which type of winding is induction motor?
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 main parts of an induction motor?
Like any other electrical motor, induction motor have two main parts namely rotor and stator. Stator As the name indicates stator is a stationary part of induction motor. A three phase supply is given to the stator of induction motor. Rotor The rotor is a rotating part of induction motor.
What are the parts of an induction motor?
Parts of an Induction Motor
- The A.C. Induction Motor has three main parts, rotor, stator and enclosure. …
- The stator is the stationary part of the motor’s electromagnetic circuit and is made up of thin metal sheets, called laminations. …
- Coils of insulated wire are inserted into slots of the stator core.
What is casing in induction motor?
Casing. The casing of the induction motor contains all of the motor components, provides electrical connections and allows for ventilation of the motor parts to reduce heat buildup. The casing design often includes fins to assist with heat dissipation.
