Type. Synchronous motors fall under the more general category of synchronous machines which also includes the synchronous generator.Generator action will be observed if the field poles are "driven ahead of the resultant air-gap flux by the forward motion of the prime mover". Motor action will be observed if the field poles are "dragged behind the resultant air-gap flux by the retarding torque ...

4. DC MOTORS Almost every mechanical movement that we see around us is accomplished by an electric motor. ... Three electrical machines (DC, induction and synchronous) are used extensively for ... 4.2 Construction DC motors consist of one set of coils, called armature winding, inside another set of coils or a set of permanent magnets, called ...
Construction of a Synchronous Machine Construction of a Synchronous Machine, i.e. alternator or motor consists of two main parts, namely the stator and the rotor.The stator is the stationary part of the machine. It carries the armature winding in which the voltage is generated.

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.
What are the main parts of a DC generator and their functions?
Synchronous machines. are principally used as . ... Construction • The conductors are secured by steel wedges. • The iron core is supported by a steel housing. ... • DC field excitation is an important part of the overall design of a synchronous generator
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.
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 Generator A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i.e. Magnetic field system, Armature and Commutator and Brush gear.

Construction of DC Machine. 1. Yoke. Yoke. Function. It provide mechanical Support for poles; It also provide protection to whole machine from dust, moisture etc. It also carries magnetic flux produced by the poles; Yoke is also called as frame. Material used. For small M/C yoke is made of cast iron.
Construction and Principle of Operation of the Shunt DC Motor
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.

Construction equipment operators use machinery to move construction materials, earth, and other heavy materials at construction sites and mines. They operate equipment that clears and grades land to prepare it for the construction of roads, bridges, and buildings, as well as runways, power generation facilities, dams, levees, and other structures.
