The armature winding of a dc machine is a closed-circuit winding; the conductors being connected in a symmetrical manner forming a closed-loop or series of closed loops. Depending upon the manner in which the armature conductors are connected to the commutator segments, there are two types of ...
The magnetic frame or theyoke of DC motormade up of cast iron or steel and forms an integral part of the stator or the static part of the motor. Its main function is to form a protective covering over the sophisticated inner parts of the motor and provide support to the armat...
CONSTRUCTION MACHINE AND ITS OPERATION INFORMATION CONTROL SYSTEMPROBLEM TO BE SOLVED: To control a construction machine reliably at a control center located at a separated position.KINUKAWA HIDEKI絹川 秀樹
The input ofa brushless DC motoris current/voltage and its output is torque. Understanding the operation of the DC motor is very simple from a basic diagram is shown below. DC motor basically consists of two main parts. The rotating part is called the rotor and the stationary part is also ...
The poles and field winding are the stationary parts of a DC generator that produce the main magnetic field in the machine. They are bolted to the inner periphery of the yoke. The poles are made of laminated sheet steel or solid cast iron or steel. The laminations reduce the eddy current...
Construction of DC Machine The construction of the DC machine can be done using some of the essential parts like Yoke, Pole core & pole shoes, Pole coil & field coil, Armature core, Armature winding otherwise conductor, commutator, brushes & bearings. Some of theparts of the DC machineis ...
Vietnam, classified as a developing nation, encounters numerous challenges within its construction sector, including the scarcity of comprehensive and documented historical data regarding risks and a deficiency in embracing contemporary methodologies to mitigate the impact of risk factors on construction proje...
HONG KONG, Jan. 6, 2025 /PRNewswire/ -- i2Cool, a trailblazer in passive radiative cooling technology, has successfully applied its green and energy-efficient paint to the rooftop and side walls of the Hong Kong Coliseum. Supported by the Environment and Ecology Bureau and Architectural Servic...
A DC generator is also used as aDC motorwithout changing its construction. Therefore, a DC motor otherwise a DC generator can be generally called aDC machine.The construction of a4-pole DC generatoris shown below. This generator comprises ofseveral partslike yoke, poles & pole shoes, field win...
Generally, generators produce a lot of heat so reduce the heat from the overheat of a machine, the cooling system is used. The exhaust system is used to eliminate the fumes during its operation. Lubrication System In a generator, there are several small as well as moving parts which are ne...
