The principle of an electric motor is based on the magnetic effect of electric current. A current-carrying loop experiences a force and rotates when placed in a magnetic field. The direction of rotation of the loop is according to the Fleming’s left-hand rule.
What is the principle of an electric motor?
Answer. An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.
What is electric motor write its principle and application?
An electric motor can be defined as; it is one kind of machine used to convert the energy from electrical and mechanical. Most of the motors work through the communication among the electrical current and magnetic field of the motor’s winding for generating force in the form of shaft rotation.
What is the principle of electric motor and electric generator?
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.
Which description best explains a motors working principle?
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 an electric motor explain with diagram?
Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. A force acts on the coil which rotates it continuously.
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.
What are the applications of motor?
The applications of electrical motor include the following. The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
What are the parts of electric motor?
The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.
What are the practical applications of motor and generator?
Hence, the use of DC machines, i.e., DC generators and motors are very limited. They are mainly used in supplying excitation of small and medium-range alternators. The Industrial Applications of DC Machines are in Electrolytic Processes, Welding processes and Variable speed motor drives.
What are the similarities and dissimilarities between a motor and electric generator?
The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor.
Can an electric motor generate electricity?
You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.
What is electric motor class 10th?
Electric motor is a device that converts electrical energy to mechanical energy. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD.
What is the working 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.
How does a 12v motor work?
Brief Overview of a 12v DC Motor
Most often, this type of motor relies on forces that magnetic fields produce. Regardless of the type, DC motors have some kind of internal mechanism, which is electronic or electromechanical. In both cases, the direction of current flow in part of the motor is changed periodically.
What is the principle of generator?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet.
