Write the difference between electric motor and dynamo.
1 Answer
The difference between electric motor and dynamo:
| Electric motor | Dynamo | |
| 1. | It converts electrical energy to mechanical energy | It converts mechanical energy to electrical energy |
| 2. | It is based on motor effect | It is based on electromagnetic induction |
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.An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.
The working principle of the electric motor mainly depends on the interaction of magnetic and electric field. The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.An electric rotor. An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field
Dynamos and Generators convert mechanical rotation into electric power. Dynamo - a device that makes direct current electric power using electromagnetism. It is also known as a generator, however the term generator normally refers to an "alternator" which creates alternating current power.
