Dc machines 1. 3/23/2007 ELEC A6 DC Machine1Lecture NotesELE-A6DC Machine 2. 3/23/2007 ELEC A6 DC Machine2DIRECT CURRENT (DC)MACHINES Fundamentals• Generator action: An emf (voltage) is induced in aconductor if it moves through a magnetic field.•
Construction Of A Dc Machine And Working Of Dc Motor As stated earlier, whether a machine is d.c. generator or a motor the construction basically remains the same as shown in the Fig. 1. Fig.1 A cross section of typical d.c. machine
Basically all machines works on the same law : Faraday’s Law of EM induction. According to which , If a current carrying loop is placed in magnetic field , it produces a torque due to which the loop rotates (Motoring action ) . Direction of motion 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.

A SIMPLE explanation of the construction and working principle of a DC Machine (DC Motor or DC Generator). Understand the parts of a DC Machine and the construction of a DC Machine. Learn more
DC Machine established its first facility in 2004, which consisted of a 250-square-foot room with one computer numerical control (CNC) machine. Since then, the company has grown by leaps and bounds. More than a decade later, DC Machine operates 70+ CNC machines and employs nearly 100 workers.
The DC motor is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article. To understand the operating principle of DC motor we need to first look into its single loop constructional feature.
DC Motors Although ac motors are used in most of the cases, DC motors have many applications and used for multi-purpose applications. DC Motor Principle A machine that converts dc power into mechanical energy is known as dc motor. Its operation is based on the principle that when a current carrying conductor is placed in a
Experiment 1 The DC Machine ECEN 4517 R. W. Erickson and D. Maksimovic The purpose of this experiment is to become familiar with operating principles, equivalent circuit models, and basic characteristics of a dc machine. Dc machines are most commonly used in control and servomechanism, as well as industrial, applications. The applications
DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor’s speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings.
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.
