Construction of DC Machine (Generator & Motor)

Categories Electrical Machines, DC Generator, DC Motor 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.

DC MACHINES - Adnan Menderes University

Electric Machines General • When a machine is converting electrical energy into mechanical form, it is operating in the MOTORING mode • When a machine converts mechanical energy into electrical form, it is operating in the GENERATING mode • Mechanically, all machines consist of two main parts: STATOR and ROTOR. • The stator is the stationary (non-rotating) part of a machine.
