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 working of electric motor Class 10?
An electrical machine through which we can convert electrical energy into mechanical energy is called an electric motor. A force is generated due to the interaction between the magnetic field of the motor and the current flowing through a wire winding. This force acts as a torque on the motor shaft and makes it rotate.
What is the electric motor describe principle and working of electric motor?
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.
How does a DC motor work class 10?
D.C. motor can be defined as a machine which converts electrical energy to mechanical energy of rotation based on the principle of magnetic effect of current. The DC motor works according to Fleming’s right hand rule. … When the armature is rotated in the clockwise direction, the split rings are connected to the brushes.
What is the working of 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 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 motor principle?
The motor principle states that a current-carrying conductor that cuts across external magnetic field lines experiences a force per- pendicular to both the magnetic field and the direction of the electric current.
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 electric generator principle?
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.
Can we convert motor to generator?
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 a commutator Class 10?
Commutator is an attachment, connected with the armature of a motor or dynamo, through which electrical connection is made and which ensures the current flows as direct current. a device for reversing the direction of flow of electric current.
What is armature class 10th?
(i) Armature: It is a rectangular iron core wrapped by the copper coil through which electricity passes and due to magnetic field it experiences a force and rotates. (ii) Brushes: It conducts current between stationary wires and moving parts, most commonly in a rotating shaft.
What’s the difference between AC and DC motors?
The most basic difference is the power source. A.C. motors are powered from alternating current (A.C.) while D.C. motors are powered from direct current (D.C.), such as batteries, D.C. power supplies or an AC-to-DC power converter.
How many types of motor are there?
Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.
How does motor start?
A three phase Induction Motor is Self Starting. When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor starts rotating and the induction motor starts. At the time of starting, the motor slip is unity, and the starting current is very large.
