Question

what is the principle of motor and generator?​

Answer 1

Answer:

speak in much simpler words, the above statement states that , if

you place a a conductor in a (often denoted Φ or ΦB)and that conductor has relative motion with respect to that flux, an

(denoted by epsilon and measured in volts)is generated and the amount of that E.M.F generated is given by the equation

Working principle of a DC generator :-

Important thing you need to understand about a DC generator

The main aim of a generator is to "Generate electrical power from an available mechanical energy source" i.e "To convert Mechanical energy to Electrical energy"

In order to achieve that we need these things

A , which can be generated by those magnets (two grey colored blocks) and direction is from north (N) to south (S).

A conducting coil which can rotated in that flux.

Now, with the help of any mechanical energy either it may be the potential energy of water in a dam , or pressurised steam in a thermal plant, rotate the coil and by that we can have E.M.F generated.

Although I've said in my heading that this is a DC generator, this specific model needs another device called "" in order to give out DC voltage.

Working principle of a DC motor :-

Important thing you need to understand about a DC generator

The main aim of a generator is to "Generate mechanical power from an available electrical energy source." i.e "To convert Electrical energy to Mechanical energy."

As you can see setup is little similar to the DC generator ,

We have here,

A Magnet.

A current carrying conducting coil

A voltage source.

Now , as the current carrying conductor is placed in the flux field , there's a torque acted upon the coil and it starts rotating.

All of these three components always co-exist.

Mechanical torque

Electric Force

Magnetic flux.

If any of the one is missing , other one is generated.

DC generator is the example of the case where 1 and 3 are present and 2 is produced.

DC motor is the example of the case where 2 and 3 are present and 1 is produced.

Now, If we have a coil wound around a current carrying conductor and has been applied with some voltage, a magnetic flux is generated.(which is the last case)
