Electrical Machine Types with operation QUICK EXPLANATION


Continuous Electro-mechanical energy conversion devices are known as Electrical machines. Which is a reversible process. Electrical machines are machines that are either used to transfer or the generation of Electrical power. These may be low-power or high-power devices(in mV or kV). Here I am discussing the high-power devices in this article. Types of Electrical Machines: … Read more

Geometrical Neutral Axis (GNA) and Magnetic Neutral Axis (MNA)

Geometrical Neutral Axis (GNA) and Magnetic Neutral Axis (MNA)

What are the Geometrical neutral axis (GNA) and Magnetic neutral axis (MNA)? The Geometrical Neutral axis (GNA) bisects the angle between the two poles of a machine. Whereas the Magnetic Neutral axis (MNA) is the perpendicular axis on the magnetic flux line. Also machine has a “Direct (D) axis” and “Quadrature (Q) axis”. What is a … Read more

Lap and Wave winding with Equalizer ring & Dummy coil


A rotating machine has an essential part known as Armature winding. Generally, this is responsible for making a rotating magnetic field in a machine. As a result, it provides back emf to the supply. This armature winding is classified into two types. One is Lap winding and another is Wave winding. These have their special … Read more

Open coil winding and Closed coil winding of DC machine

Open coil winding and closed coil winding are the types of Armature windings. Armature windings are the non-salient pole type and usually are symmetrically distributed in the slots of the complete circumference of the armature. Basically two types of armature windings according to the degree of closure produced: Open Coil Winding: Open coil windings are … Read more

Armature core of a DC machine

In the case of DC generators – Mechanical Input is applied to the shaft/rotor (i.e, Armature) and Electrical output is collected from Armature itself. In the case of DC Motors – Electrical Input is applied at the Armature terminal and mechanical output at the rotor is received(i.e, Armature). Therefore armature is the center for electromechanical … Read more

By the end of this article, you will be able to know everything about the Speed control of the DC machine. So be there … Read more

What is the Need of Synchronizing two Different Power Sources

What is the Need of Synchronizing two Different Power Sources

Synchronizing two different power sources is essential in various electrical and power systems to ensure a seamless and stable supply of electricity. The need for synchronization arises in situations where multiple power sources, such as generators or power grids, are connected to a common electrical system. Here are some key reasons for synchronizing two different … Read more

Difference between Concentrated winding and Distributed winding


Electromagnetic armature winding creates magnetic poles, which can be concentrated as a single north and south pole in a concentrated winding configuration. However, in a distributed winding configuration, the armature has multiple north and south poles. Concentrated Winding: According to concentrated winding, the coil turns are concentrated in one place. So no production of the … Read more
