Apr 26, 2019 A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC Construction, Classification, and Applications of DC Machine According to the source of supply, electrical machines are classified into two types; AC machine and DC machine. For example, DC Motors, DC Generator etc. Jan 01, 2020 Construction of DC Machines. In the structure of DC machine either dc motor or generator, there are 2 main parts first one is the static or the second one is moving. The static part is stator and moving part is rotor. In stator of dc machine, there is a frame that provides protection and support to internal structure from external environment Oct 07, 2019 A DC machine is used to operate the devices which use unidirectional current. When we evaluate with DC machines, Alternating Current machines have more advantages because of the losses that appear in DC. Though the losses are more, DC machines find its importance in modern day to day life. It has its unique feature of generating unidirectional Nov 10, 2015 Although the battery is an important source of DC electric power, it can only supply limited power to any machines. There are some applications where large quantities of DC power are required, such as electroplating, electrolysis, etc. Hence, at such places, DC generators are used to deliver power.
