Basic Construction Of Dc Machines

Basic construction and working of a DC Generator

DC Generator. A dc generator is an electrical machine which converts mechanical energy into direct current electricity.This energy conversion is based on the principle of production of dynamically induced emf. This article outlines basic construction and working of a DC generator.. Construction of a DC machine:

DC Machine Construction, Working, Types and Applications

Apr 15, 2020· Working of DC Machine. The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field. The direction of this produced torque can be found by the Fleming’s left hand rule (thumb is the force).

DC Machine Construction, Working, Types, EMF Equation

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

What is a DC Machine? Basic structure & Equivalent circuit

Nov 10, 2015· Basic Structure of Electrical Machines. The rotating electrical or DC machine has mainly two parts; one is Stator, and another one is Rotar. The stator and rotor are separated from each other by an air gap. The stator is the outer frame of the machine and is immovable. The rotor is free to move and is the inner part of the machine.

The armature core of a DC generator or machine serves the following purposes. It houses the conductors in the slots. It provides an easy path for the magnetic flux. As the armature is a rotating part of the DC Generator or machine, the reversal of flux takes place in

DC Motor Basics, Construction, Types & Its Application

Electric machines are a method of converting energy. Motors take electrical energy and produce mechanical energy. Electric motors are utilized to power hundreds of devices we use in everyday life. Electric motors are broadly classified into two different categories: Direct Current (DC) motor and Alternating Current (AC) motor.

Oct 26, 2020· A stator is the static part of the DC machine that houses the field windings and receives the supply. A rotor is the rotating part of the DC machine that brings about the mechanical rotations. All these parts put together make up the total construction of a DC motor.

Classifications of DC machines : (DC Motors and DC

Each DC machine can act as a generator or a motor. Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad categories of dc machines; (i) Separately excited and (ii) Self-excited.
