The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What is the principle of electric motor state the function of split ring?
The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this the coil continues to rotate in the same direction.
What is an electric motor state the principle on which electric motor works what is function of commutator in motor?
Commutators are used in direct current (DC) machines: dynamos (DC generators) and many DC motors as well as universal motors. In a motor the commutator applies electric current to the windings. By reversing the current direction in the rotating windings each half turn, a steady rotating force (torque) is produced.
What is motor principle?
Definition. A current-carrying conductor will experience a force when placed within a magnetic field. The principle of the electric motor is that it converts electrical energy into kinetic energy (mechanical energy) through the interaction of the two magnetic fields.
What is the function of commutator in electric motor?
On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What is the function of armature in electric motor?
In the armature, an electromotive force is created by the relative motion of the armature and the field. When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft.
What is the main function of the commutator?
The function of commutator ring in an electric motor is to reverse the direction of current flowing through the coil every time coil just passes the vertical position during a revolution. Hence as the direction of the current is reversed, the torque is changed in the direction.
Can commutator convert AC to dc?
It doesn’t convert to ac. The armature coils are first connected to dc from the brushes, and current flows in one direction through the armature coil. Then, the coil rotates to align the magnetic field. When it rotates, a new set of commutator contacts are positioned at the brushes.
What is motor diagram?
AC Motor Diagrams – Basic Stator and Rotor Operation. An AC Motor converts electric energy into mechanical energy. An AC Motor uses alternating current – in other words, the direction of current flow changes periodically.
What are the types of motors?
Types of Electric Motors

What is motor and its types?
The working principle of the electric motor mainly depends on the interaction of magnetic and electric field. The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
