A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
How do simple electric motor and generator operate?
When an electrical current is applied to the motor, the magnets or windings create a magnetic field that both attracts and repels the rotor, causing it to spin. … Rather than using electricity to create motion, electric generators in Lethbridge convert mechanical energy into electrical energy.
What is the operation of a simple electric motor?
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.
What is the function of electric motor and generator?
Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.
How does a simple electric generator work?
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. … When the coil rotates, it cuts the magnetic field which lies between the two poles of the magnet.
Which motor is used in generator?
The DC motor is best suited for a generator. It’ll produce current, even if the speed of the rotation is somewhat less. When you use a single phase motor, you’ll need to rotate it at a speed higher than the motors synchronous speed to generate energy.
What is difference between electric motor and generator?
An electric motor is a machine that converts electrical energy to mechanical energy. An electric generator is a machine that converts mechanical energy to electrical energy. … In a motor, current is supplied to the armature winding. In a generator, current is produced in the armature winding.
What factors affect the operation of a simple electric motor?
Factors Affecting Motor Performance
- Voltage of Power Supply.
- Type of Power Supply.
- Winding Specifications.
- Environmental Temperature.

What is the price of electric motor?
Questions & Answers on Single Phase Electric Motor
|Power||Min Price||Max Price|
|10-100 KW||Rs 3500/Piece||Rs 8000/Piece|
|<10 KW||Rs 2000/Piece||Rs 8500/Piece|
What is a simple motor?
The simple motor built in class uses a coil that is a temporary electromagnet. This coil gets the force to help create torque from the electrical current supplied by the battery. The donut magnet used in the motor is a permanent magnet, which means it has a north and a south pole that are permanently in place.
What are the similarities and difference between electric motor and 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.

How does AC and DC generator work?
An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. … The two ends of the coil are attached to the commutator, which balances the charges to and from the generator, thus resulting in a current that does not alter direction.
