Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the difference between N- and P-type semiconductors. Semiconductor substances are materials that have conductivity properties between conductors and insulators. Their conductance is restricted due to the small number of free electrons and holes in the valence…
Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the lap winding in DC machines. The rotating part, which is the rotor of any DC machine, whether it is a motor or DC generator, has a very important part of the machine that is the…
Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the Commutation and Armature Construction in Real DC Machines. In DC machines there are many methods to join armature windings with the commutators. These methods of connection define the no of parallel paths for current in…
Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss commutation in a four-loop DC machine. The voltage generated at the output terminals of DC machines is pure AC voltage. To convert these voltages into DC voltage, commutators are introduced at the terminals that convert the…
Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will discuss the Simple Rotating Loop between Curved Pole Faces. There are two main types of DC machines. The first is a DC motor, and the second is a DC generator that produces electrical power through mechanical energy,…
Hello, fellows, I hope all of you are having fun in your life. In today’s tutorial, we will have a look at Introduction to DC Machines. Like alternating current machines, there are 2 types of DC machines. The first one is a DC motor that converts electrical power into mechanical power, and the second one…
Hello, fellows. I hope all of you are having fun in your life. In today’s tutorial, we will have a look at what armature reaction is. In the DC machine, either it is a DC generator or a DC motor and has 2 types of windings, like an AC machine, such as an induction motor,…
