DC Machines: Generator and Motor, Back Emf
DC Generators 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 Machine: Theoretically, a DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. Therefore, a DC generator or a DC motor can be broadly termed as a DC machine . These basic constructional details are also valid for both DC Generator and DC motor . Hence, let's call this point as construction of a DC machine instead of just 'construction of a dc generator'. The above figure shows constructional details of a simple 4-pole DC machine . A DC machine consists of two basic parts; stator and rotor. Basic constructional parts of a DC machine are described below. Yoke: ...
