Construction Of DC Machine (Generator Motor)
2014.6.25 The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. In this article, we will explain the construction of dc machine in detail. Read: Working of DC Motor.
