tricks with dc toy motor

TRICKS WITH TOY MOTOR

it was a cool day i was lying on my bed, suddenly an idea striked me to make a  fan with dc toy motor which will be operated on battery and can be used as a handfan during power cutoff or loadshedding.

i went to the market and brought a dc motor of 6v.
i feel laughing at this incidence of mine, i was a new comer to the field of science that time but yet i had a innovative skill.

now here's the fact behind my laugh, my experiment.

i connected the positive and negative terminals, and connected it to a supply of 220v mains

and my motor got worn out,fused up, sparks came out and motor was burning and heated up.

but a cool day came again yesterday,and saw my worn out dc motor inside my garbage kit bag and thought of repairing it.

 then i took out the cap of the motor  saw two lead wires.
the motor shaft rotates when this lead wire is connected to the shaft at opposite directions.
i took out the lead terminals directly supplied a 6v connection on the shaft with both positive and negative  opposite to each other and the shaft started rotating.

now the thing which i learnt is my motor was not worn out,short circuited or anything whatever u say

actually when we supply more or incorrect voltage to such type of motors it never gets worned out just the lead terminals get blasted up and it stops working  you can try to operate it later with the correct voltage as i did in the same way.

but if the coil inside the matter is worn or broken out then it will not work in that case take out all the wires wrapped in it and then wrap a new wire and connect each wire ends to different point of the shaft and then try what i did.

or the better would be to use a resistor for the safety of motor.

wish u a happy vacation to discover more facts

feel free to comment below if you have any queries or suggestion beacuse i wish to learn more from anyone who wish to teach me....................
