WebAug 13, 2024 · Here is the schematic diagram of a DC Generator. A DC generator consists of six main parts, which are as follows. Yoke. The outer frame of a DC generator is a hollow cylinder made up of cast steel or rolled steel is known as yoke. The yoke serves following two purposes. It supports the field pole core and acts as a protecting cover to the machine. Webconstruction for a salient pole machine, with 2 poles. Note that Fig. 5 only represents one “side” of each phase, so as to not crowd the picture too much. In other words, we should also draw the Phase A return conductor 180° away from the Phase A conductor shown in the picture. Likewise for Phases B and C. A Two Pole Machine (p=2)
WebA DC motor is used to convert the direct current (DC) electrical power into mechanical power based on the forces produced by magnetic filed (s). The output of the motor is mechanical power in terms of rotation (speed) of the shaft. According to the applications, we need to change the speed of the motor. WebDC Motors Although ac motors are used in most of the cases, DC motors have many applications and used for multi-purpose applications. DC Motor Principle A machine that converts dc power into mechanical energy is known as dc motor. Its operation is based on the principle that when a current carrying conductor is placed in a
