Electric Drives Electrical Machine Fundamentals Basic construction and working of a DC Generator

Similarly when the machine is used as a DC motor the commutator switches the DC supply voltage to alternate arms of the coil each half cycle in order to achieve unidirectional rotation Thus in all wound rotor DC machines both motors and generators the current in the rotor windings is AC and it is the commutator which enables the corresponding DC input or output There are however some Thus a DC generator or a DC motor can be broadly termed as a DC machine These basic constructional details are also valid for the construction of a DC motor Hence let s call this point as construction of a DC machine instead of just construction of a dc generator

Electrical Machines FundamentalsWorking Principle of DC Motor studyelectrical

Synchronous machine construction A synchronous machine has two mechanical parts a rotor and a stator There are also two electrical parts to the machine a field source and an armature winding These basic fundamentals of an electric machine are like those for a DC machine with one significant difference The field source of a synchronous machine is on the rotor the armature winding of a An Electric DC motor is a machine which converts electric energy into mechanical energy The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field it experiences a mechanical force
