1 DC DRIVES Principle of operation and construction – a review DC machine consists of stator – stationary – where the field flux is produced
A motor is an electrical machine which converts electrical energy into mechanical energy. Construction of a DC motor is same as that of a DC generator. This article explains the basic working principle of a dc …
A DC Motor like we all know is a device that deals in the conversion of Electrical energy to mechanical energy and this is essentially brought about by two major parts required for the construction of dc motor…
The shunt DC motor has the field winding in parallel with the armature (Fig. 1). In a parallel circuit, the magnitude of voltage drop across each parallel element is the same, while the magnitude of current through each parallel branch is a function of the impedance of the element.
Synchronous machine construction. A synchronous machine has two mechanical parts: a rotor and a stator. There are also two electrical parts to the machine: a field source and an armature winding. These basic fundamentals of an electric machine are like those for a DC machine, with one significant difference: The field source of a synchronous machine is on the rotor, the armature winding of a ...
A DC Machine is an electro-mechanical energy conversion device. There are two types of DC machines; one is DC generator, and another one is known as DC motor. A DC generator converts mechanical power
Construction of DC Machine (Generator & Motor) The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc

Principles and Working of DC and AC machines Dr Jagadish Nayak . BITS Pilani Dubai Campus Constructional features . BITS Pilani, Dubai Campus DC Generator DC Machines . BITS Pilani, Dubai Campus A generator consists of a stationary portion called the stator and the rotating portion called the rotor. A magnetic field is produced when a direct current is applied to windings of the coil in the ...
Figure 1 shows elementary permanent- magnet machine. It is very similar to the AC machine; however, instead of a pair of slip rings to connect to the ends of the coil, there is a single split ring.
2016-09-25· Video Lecture on Construction of DC Machine and its components of Chapter DC Machine of Subject Basic Electrical Engineering for First-Year Engineering Students.
To understand the operating principle of DC motor we need to first look into its constructional feature. The very basic construction of a DC motor contains a current carrying armature which is connected to the supply end through commutator segments and brushes.
In this lesson i am going to explain you about construction of DC machine in which i explained all the important components of dc machine like yoke, commutator, poles ...
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
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.
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
DC Machine Construction (Motors Generators Guide) Before going on to examine the characteristics of the dc motor and dc generator in detail, we will look at how these
