What are the possible outcomes if I insert the shaft that usually spins a fan blade etc into the tip of my Dremel and turn it on? Will it create electricity and if so what would happen if I shared it out by touching something metal to both +/- at the other end of the motor?
In: Engineering
Motors and generators are basically the same thing. They are spiral of wires around a spinning magnet.
If you apply current to the wires you create a magnetic field and that will cause the magnet to spin.
If you spin the magnet instead, the flip flopping of poles of the magnet will create a flow of electrons in the wire thru induction.
If you spun your electric motor via your dremel and connected to the positive and negative terminals you could possibly have enough current to power a light or something. (I say possibly because most electrical devices have diodes to keep current flowing one direction. ) Using a motor as a generator isn’t very efficient. Motor windings are designed to take electricity and create desired torque. Likewise generators are design to generate the most amount of current with the least amount of input torque.
