What are the main parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What is the main function of a DC motor?
A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields.
What are the similarities and differences between DC motor and DC generator?
Difference between DC Motor and DC Generator
|Input/output||Motor has a DC Current as an input and provides mechanical output|
|Commutation||Motor uses commutators for changing the magnetic field polarity|
|Electromotive force (EMF)||Emf is utilized by coil and useful for rotating the axle|
What is the working principle of DC motor and DC generator?
DC generator operates on the principle of the dynamically induced electromagnetic force. When a conductor is placed in a varying magnetic field, an electromotive force gets induced within the conductor. This induced e.m.f magnitude is measured using the equation of the electromotive force of a generator.
What are the 3 types of DC motors?
There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
What is a DC generator used for?
Applications of DC Generators
These generators are used to charge batteries, provide lighting and provide excitation to alternators. They are used to provide field excitation current for regenerative braking in DC locomotives. They are used in DC motors where speed control is necessary.
Why is it called DC generator?
A DC generator or direct current generator is one kind of electrical machine, and the main function of this machine is to convert mechanical energy into DC (direct current) electricity. The energy alteration process uses the principle of energetically induced electromotive force.
