Why is 3 Phase Induction Motor Self Starting?
In a three phase system, there are three single phase lines with a 120° phase difference. So the rotating magnetic field has the same phase difference which will make the rotor to move. If we consider three phases a, b, and c when phase a gets magnetized, the rotor will move towards the phase a…

Types of Induction Motors
The types of induction motors can be classified depending on whether they are a single phase or three phase induction motor. Single Phase Induction Motor The types of single phase induction motors include: Split Phase Induction Motor Capacitor Start Induction Motor Capacitor Start and Capacitor Run Induction Motor Shaded Pole Induction Motor Three Phase Induction…

Working Principle of Induction Motor
We need to give double excitation to make a DC motor to rotate. In the DC motor, we give one supply to the stator and another to the rotor through brush arrangement. But in induction motor, we give only one supply, so it is interesting to know how an induction motor works. It is simple,…

What is an Induction Motor?
An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. The rotor of an induction motor can be a squirrel cage…

Commutator in DC Machine
Role of Commutator The commutator connects the rotating armature circuit to the stationary circuit. As we know, the armature is a rotating part. And the load or source connected with the DC machine must be connected with the stationary terminals. Hence, the commutator and the brushes help to connect the rotating armature conductors to the…

Armature Winding in DC Machine
Armature winding is defined as an arrangement of conductors to produce EMF by relative motion in a magnetic field. In a DC machine, the armature is a rotating part. And it provides housing to the armature winding. There is a number of slots available in the armature core and these slots in which conductors are housed.…

Power Stages and Efficiency in DC Machine
In this article, we will discuss Power Stages and Efficiency in DC Machine. This helps to determine the performance of the DC machine. The power flow analysis of any machine is important to determine its characteristics of the machine. In the operation of any machine, the input power is delivered to a machine at some definite…

Losses in DC Machine
The DC machine is used to convert the electrical power into mechanical power or mechanical power into electrical power. During the conversion of energy, always there are some amounts of energy are lost. In this article, we will discuss different losses occurs in DC machine. This energy converted into heat is called energy loss. The energy loss…

Working Principle of DC Generator by Single loop Gen.
To understand the working of the DC generator, take a single loop generator. The figure of this generator is as shown in the below figure. A loop made from two conductors. Conductor-1 is AB and conductor-2 is CD. A single loop ABCD is made from these conductors. As shown in the above figure, a rectangular…

EMF Equation of DC Generator
EMF Equation of DC Machine Consider a DC machine with the following parameter; P = Number of poles Ф = Flux per pole (Wb) A = Number of parallel paths in the armature Z = Total number of Armature conductor N = Speed of Rotor (RPM) Now, ф is the flux produced by one pole. If there is P number of poles presents in…
