It's a pleasure to watch fabrication process of windings in the factories. What you see here is a fully automatic winding process. The windings take in electric current and create a Rotating magnetic field out of it. This RMF is responsible for the motor's rotation. You might be curious about how this Magnetic field rotates even when the windings are stationary? Let's unveil its working, come along!
There are two types of windings for electric motors. In this video I will show you the advantages and the disadvantages of the two types of windings. Windings for electric motors can be divided into concentrated windings and distributed windings. In a distributed winding, the winding is always wound over at least two stator teeth. In a concentrated winding, on the other hand, only one stator tooth is injured. Electric motors with concentrated winding are shorter and easier to manufacture. A motor with a concentrated winding can generate more torque due to the trapezoidal back EMF. However, the losses in the copper and sheet metal are greater. With a distributed winding, you can achieve a higher efficiency, which is very important for electric vehicles. Other distinguishing features, which are important for the design of the winding, are fractional and integral slot windings as well as single layer and double layer.
