Construction of DC Machine (Generator Motor)

2021-11-11  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. Read: Working of DC Motor. All dc machines have five principal components.
