An electric motor is a device which converts electrical energy into mechanical energy. Electric motors and their functions: A power supply – In general, a simple motor has a DC power source. It provides power for the armature of the motor or 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 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 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 an electric motor with the help of a diagram describe the principle and 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. … When current is passed into the coil, it produces a magnetic field around it. The two magnetic fields interact and cause the coil to rotate.
What is electric motor explain with diagram?
1) When electric is passed into the rectangular coil, magnetic field is produced around the coil. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.
Why are electric motors important?
More than 40% of generated electricity is consumed by industry, and two-thirds of that energy is used by electric motors. By using more efficient motors it would be possible to achieve huge savings in both energy and carbon dioxide emissions.
What is the function of commutator in an 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 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 main parts of an 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 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
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 the principle of electric 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 conductor coil along with its core is known as an armature.15 мая 2019 г.
