Answer. A motor is an electrical machine which converts electrical energy into mechanical energy. The principle of working of a DC motor is that “whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force”.
What is the principle of an electric motor?
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 Class 10 Brainly?
Answer. The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. A current carrying conductor placed perpendicular to magnetic field experiences a force.
What is the principle of an electric motor briefly explain the construction and working of an electric motor using a Labelled diagram?
Principle: An electric motor works on the principle that a current carrying conductor placed in a magnetic field experiences a force, the direction of force is given by Fleming’s left hand rule.
What is the basic principle of DC motor?
DC motors operate on Faraday’s principle of electromagnetism which states that a current-carrying conductor experiences a force when placed in a magnetic field.
What is an electric motor explain with diagram?
An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.
How an electric motor works step by step?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What is the role of commutator in electric motor?
The commutator assures that the current from the generator always flows in one direction. … 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.
How does a Class 10 electric motor work?
Principle of Electric Motor
The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. A current carrying conductor placed perpendicular to magnetic field experiences a force.
What is role of split ring in an electric motor?
Role of Split Ring in an Electric Motor
Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed.
What is the function of brushes in electric motor?
A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators.
What are the applications of electric motor?
The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
What is the principle of electric motor and electric generator?
Electric generator follows Fleming’s right-hand rule. The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field. The working principle of generator is based on electromagnetic induction.
What are the 3 types of DC motors?
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 are the advantages of DC motors?
DC motors also offer their own advantages, such as:
- Simpler installation and maintenance.
- High startup power and torque.
- Fast response times to starting, stopping, and acceleration.
- Availability in several standard voltages.
How does a 12v DC motor work?
In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate. A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil.
