Construction, Classification, and Applications of DC Machine Working of DC Machine. The working principle and operation of a DC machine is based on an effect when a current carrying... Construction of DC Machine. The DC machine consists of Yoke,
Construction of DC Machine. Yoke. Another name of a yoke is the frame. The main function of the yoke in the machine is to offer mechanical support intended for poles and protects Pole and Pole Core. Pole Shoe. Field Windings. Armature Core.
Oct 07, 2019· This article gives an overview of a DC machine, which includes construction, working, parts, EMF equation, types, its losses, and applications. What is a DC Machine? It is a rotating device which can be either a motor or a generator.
Types of D.C Machine with Electrical Machine, Single Phase Transformer, Construction of single Phase transformer, Losses in transformer, Open-Circuit and Short-Circuit Test, Three-Phase Transformer, Auto transformer etc.
Nov 10, 2015· There are two types of DC machines; one is the DC generator, and another one is known as DC motor. A DC generator converts mechanical power (T) into DC electrical power (EI), whereas, a DC motor converts d.c electrical power into mechanical power. The AC motor is invariably applied in the industry for conversion of electrical power into mechanical power, but at the places
Construction of dc Machines. Construction of dc Machines: The rotor in a dc machine is called an. armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field.
DC machine can be used as a motor or as a generator. DC Machine is most often used for a motor. Cutaway view of a dc motor DC motors are found in many special industrial environments Motors drive many types of loads from fans and pumps to presses and conveyors The major advantages of dc machines over generators are easy to
Self-excited DC machines: In this type, field winding and armature winding are interconnected in various ways to achieve a wide range of performance characteristics (for example, field winding in series or parallel with the armature winding). In a self
Construction of dc Machines: The rotor in a dc machine is called an. armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field. part of the machine.
Types of DC Motors. DC motors are classified according to electrical connections of armature windings and field windings. Armature windings: a winding which a voltage is induced. Field windings: a winding that produces the main flux in machines. Five major types of DC motors:-. Separately excited DC motor.
Therefore, a DC motor otherwise a DC generator can be generally called a DC machine. The construction of a 4-pole DC generator is shown below. This generator comprises of several parts like yoke, poles & pole shoes, field winding, an armature core, armature winding, commutator & brushes.
Jan 10, 2014· 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 const...
Please go through the construction of dc generator before reading this article about different types of dc generator.. A DC generator requires MMF to establish flux in its magnetic circuit. The MMF necessary to establish flux in the magnetic circuit of a dc generator is obtained by field excitation.
DC Drive Working and Types of DC Drives Tags AC Motor AC Motors Induction Motor Motors Slip-ring Induction Motor Squirrel Cage Induction Motor Three Phase induction Motor Types of Motors Wound Rotor Induction Motor
The friction and windage and core loss of the machine is 400 W. its armature copper loss on full load and shunt field loss is a. 2156.7 W, 200 W b. 2232.6 W, 200 W
Applications of DC Machines In the present day world, electrical energy is generated in bulk in the form of an alternating current. Hence, the use of DC machines, i.e., DC generators and motors are very limited. They are mainly used in supplying excitation of small and medium-range alternators.
Oct 05, 2019· Because the AC machines have more advantages compared to that of DC machines. In this article, we shall discuss what is AC motor, construction, working principle, types, speed control, and applications. AC Motor. The machine that turns the class of
Oct 26, 2020· The construction of these types of DC motor are such that, radially magnetized permanent magnets are mounted on the inner periphery of the stator core to produce the field flux. The rotor on the other hand has a conventional DC armature with commutator segments and brushes.
Construction of DC Machine - there are seven main parts of dc machine or motor generator which as follows Yoke Pole core and pole shoes Pole coil
Mar 19, 2015· Direct Current Motor (Rotor, Startor) A representative DC machine was depicted in Figure 0 above, with the magnetic poles clearly identified, for both the stator and the rotor.. Figure 1 is a photograph of the same type of machine. Note the salient pole construction of the stator and the slotted rotor. As previously stated, the torque developed by the machine is a consequence of the magnetic
Mainly there are two types of DC Motors. One is Separately Excited DC Motor and other is Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor. The dc motor converts electrical power into mechanical power.
