Electric motors operate on three different physical principles: magnetism, electrostatics and piezoelectricity. In magnetic motors, magnetic fields are formed in both the rotor and the stator.
What is the basic principle of electric motor?
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 are 3 types of motor controls?
There are four basic motor controller and drive types: AC, DC, servo, and stepper, each having an input power type modified to the desired output function to match with an application.
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.
Where are electric motors used?
Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches.
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. …

What are the basic parts of a simple electric motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator.
How do you control a motor?
Thus, the speed of a DC motor can be controlled in three ways:
- By varying the supply voltage.
- By varying the flux, and by varying the current through the field winding.
- By varying the armature voltage, and by varying the armature resistance.
How can you control the speed of a motor?
Speed Control by Variation of Supply Voltage:
This is a slip-control method with constant frequency variable supply voltage. In this method of speed control of induction motors, the voltage applied to the stator is varied for varying the speed.
What is meant by DOL starter?
A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals.
Why commutator is used in 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 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 is an 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.
