What are the two main parts of a DC generator?

A direct-current (DC) generator consists of two main parts, a rotating section and a fixed one. Stator is the stationary part of this system that includes a core, stator winding, and the outer frame and houses the rotor (the rotating part) in its core.

What is the main type of action that takes place between the stator and rotor in an AC induction motor?

As each change is made, the opposite poles on the stator attract the poles of the rotor. Thus, as the magnetic field of the stator rotates, the rotor is forced to rotate with it. One way to produce a rotating magnetic field in the stator of an AC Motor is to use a three-phase power supply for the stator coils.

Where does voltage generated in a DC generator depend?

magnetic field
The AMOUNT of voltage generated depends on (1) the strength of the magnetic field, (2) the angle at which the conductor cuts the magnetic field, (3) the speed at which the conductor is moved, and (4) the length of the conductor within the magnetic field.

What is rotor in DC generator?

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor’s axis.

What is a stator and rotor?

The stator is the stationary part of the machine, whereas the rotor is the movable part of the machine. The stator core, stator winding and the outer frame are the three parts of the stator whereas the rotor core and field winding are the parts of the rotor. The three-phase supply is given to the winding of the stator.

What determines the voltage output of a DC generator?

In a shunt-wound DC generator, the output voltage is determined by the rotational speed of the armature and the density of the stationary magnetic field flux. At a certain amount of field winding current, the generator’s field poles saturate, preventing further increases in magnetic flux.

How does a rotor and stator work generator?

In the rotating armature AC generator as illustrated in Figure 1, the stator provides a stationary electromagnetic field. The rotor, acting as the armature, rotates in the field, cutting the lines of force and producing the desired output voltage.
