Question

Name four appliances wherein an electric motor, a rotating device that converts electrical energy to mechanical energy, is used as an important component. In what respect motors are different from generators?

Answer 1

Explanation:

Following are the appliances consisting of electric motor converting electric energy into mechanical energy:

1. Vacuum cleaners.
2. Washing Machines.
3. Ceiling fans.
4. Grinders and mixers.

Difference between motor and generator:

Electric motor	Electric generator
An electric motor is a kind of machine which converts electrical energy into mechanical energy.	An electric generator is a kind of machine which converts mechanical energy into electrical energy.
Electric motor follows Fleming’s left-hand rule.	Electric generator follows Fleming’s right-hand rule.
The working of a motor is based on the conductor(current-carrying) that experiences a net force when it is kept in the magnetic field.	The working of the generator is totally based on the laws of electromagnetic induction.
The main shaft or propeller shaft of an electric motor is driven by the influence of magnetic force which is induced between the armature and field.	The shaft of an electric generator is connected to the main rotor which is driven by a mechanical force by some external link say some diesel engine.
In this case, the current is directly supplied to the winding of the armature.	In the case of a generator, the current is produced in the winding of the armature.
Ceiling fans, cars, etc. are all examples of motors.	The generator is used to generate electricity in power stations and other places.
