An electric motor utilises the magnetic effect of current. It 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 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 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 metals are used in electric motors?
Powder metal components for motors generally consist of iron, nickel, and cobalt.
- Iron is the cheapest of the three, so many designers tend to turn to there first.
- Cobalt is rarely used on its own, but is sometimes added to iron. …
- Nickel is expensive but valuable to motor applications.
How does an electric motor work simple?
This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.
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.
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 Motor and its working principle?
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 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 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 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?
Are old electric motors worth anything?
electric motor and it is worth $0.15 per lb in scrap (prices vary of course depending on market demands, etc.) which means that motor is worth $1.50 as-is. If you take that electric motor apart you will need tools, time, and patience.
Is there gold in electric motors?
Silver, platinum and gold are influential in electronic motors and phones. … Silver-zinc batteries are often used to power smartphones and electric motors.
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 are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
What are the types of electric motor?
