Category: DC MACHINES GENERATORS AND MOTORS

A device (machine) that makes possible the conversion of energy from electrical to mechanical form or from mechanical to electrical form is called an electro-mechanical energy conversion device or electro-mechanical transducer, as shown in Figure 11.1. Fig. 11.1  Electro-mechanical energy conversion Depending upon the conversion of energy from one to the other, the electromechanical device can be…

A DC machine is an electromechanical energy conversion device. It can convert mechanical power (ωT) into DC electrical power (EI) and is known as a DC generator. On the other hand, when it converts DC electrical power into mechanical power, it is known as a DC motor. Although battery is an important source of DC…
