DC Generator
· It is a machine that converts the mechanical energy supplied into electrical energy. The output obtained from the generator is direct current. Apart from this, we had also studied the construction, working, how EMF is generated, the basics of armature reaction, characteristics, advantages, and appliion of DC generator.
Construction of a Synchronous Machine
Construction of a Synchronous Machine, alternator or motor consists of two main parts, namely the stator and the rotor. The stator is the stationary part of the machine. It carries the armature winding in which the voltage is generated. The output of the machine is taken from the stator.

Direct Current Motor Basics | ECM
1/10/2003 · Direct Current Motor Basics. The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction motor, alternating current (AC) machines largely replaced DC machines in most appliions.
Commutation in DC Machine
Commutation in DC Machine. The currents induced in the armature conductors of a DC generator are alternating in nature. The change from a generated alternating current to the direct current applied involves the process of Commutation. When the conductors of the armature are under the north pole, the current which is induced flows in one direction.

DC MACHINES
Direct current machines may be magnetized in two different ways: • They may be magnetized by supplying current to the field winding from a separate source, such as a battery, etc. This type of excitation is called separate excitation. • They may generate their own magnetizing currents. This type of excitation is called self excitation.
Synchronous Machines Introduction
construction is less expensive, all hydromachines use salient pole construction. Fig. 8 illustrates several different constructions for smooth and salientpole rotors. The red arrows indie the direction of the flux produced by the field windings. • Synchronous generator Rotor construction Round Rotor Salient Pole Two pole w s = 3600 rpm ...

· The ideal battery on the left has no internal resistance, and so our Ohm's Law calculations for current (I=E/R) give us a perfect value of 10 amps for current with the 1ohm load and 10 volt supply. The real battery, with its builtin resistance, further impeding the flow of current, can only supply amps to the same resistance load.

Classifiions of DC machines : (DC Motors and DC ...
Each DC machine can act as a generator or a motor. Hence, this classifiion is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad egories of dc machines; (i) Separately excited and (ii) Selfexcited.
