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 principle of an electric motor Class 10?
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 an electric motor Brainly?
Answer. 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.
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 the principle of motor and 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 is motor principle?
12.2 Introduction and definition of the motor principle
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 electric motor 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.
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 is the working of electric motor?
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 split ring in an electric motor Brainly?
the role of the split ring (called commutator) in an electric motor is to reverse the direction of current flowing through the motor coil after every half rotation of the coil.
What are the types of motors?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
- DC Brushless Motors. …
- Direct Drive. …
- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
What is the working principle of AC motor?
An AC motor works by applying alternating current to stator windings, which produce a rotating magnetic field. Because the magnetic field rotates in this way, an AC motor does not need power or mechanical aid to be applied to the rotor. … The speed of rotation varies based on the number of magnetic poles in a stator.
Who is an armature?
In electrical engineering, an armature is the component of an electric machine which carries alternating current. … 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 working 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. … The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.15 мая 2019 г.
What are 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 motor be used as generator?
A motor will generate electricity if it is turned by a source of power such as a gasoline engine if it is of the proper design. Permanent magnet motors would probably be the best choice as you would not have to energize a field coil on the motor.
