how to convert any low rpm dc motor into high rpm 775 dc motor

in this video we learn how to convert low rpm dc motor into high rpm 775 dc motor easy at home. Here we use 3 same company dc motor. 

• 
  1st motor rewind with 22 swg wire. (10 turn each coil)
  
• 2nd motor rewind with 26 swg wire. (20 turn each coil) 
• And 3rd motor leave it with 32 swg wire. (100 turn each coil)

Now we try run all motors with 4 volt power step by step.

• when we run 32 swg winding motor with 4v then its speed is very low. 
• And when we run 26 swg winding motor with 4v then its speed is little high from 32 swg winding motor.
• When we run 22 swg winding motor with 4v then its speed is very high rpm and very powerful.

Mean if we use thick wire for winding then we get low rpm, And if we use fat wire for winding then we get high rpm of any dc motor. 

So if we want to increase rpm of any dc motor then we need to rewind it with high swg wire.

we learn it more battery with watching video.
