Simple battery small motor production
This is because the coil through which the current passes will be magnetic, and like the magnet, it has the north and south poles, the same polarity repels, and the opposite pole attracts. In this simple motor, the wire that scrapes half of the patent leather is used as an automatic switch, so that the current in the coil is intermittent, and sometimes there is no magnetic. When there is a current, the coil rotates due to the magnetic force between the magnet and the coil; when there is no current, the coil continues to rotate due to inertia until the current is generated, and the force is continuously rotated.
Simple battery small motor manufacturing methodRequired tools: enameled wire, two copper wires of about ten centimeters, sponge, battery, round magnet, tape
Steps and illustrations:Wrap the enameled wire into a rectangular coil that can be wrapped around the rubber. After winding it, it is rectangular, about ten times. Wrap it around and take it out from the short side of the rectangle, leaving 3,4 cm on each side. Use a knife to scrape off the paint on one side and scrape off the paint on the other side.
Roll two copper wires into a small circle
Place the round magnet on the sponge (I used pearl cotton here). Place the battery on the magnet and the diameter of the battery and magnet are the same. Put the battery in the center of the magnet, and if you can't stop at the center, turn it slowly.
Insert the copper wire on both sides of the magnet and fix it with adhesive tape. The copper wire can be slightly bent slightly in the middle. Make sure that both ends of the battery are in contact with the copper wire. It can also be fixed with tape, but it will keep turning until the battery is dead.
Put the two sides of the coil in a small circle on the copper wire, turn the coil by hand, it will keep turning down.
The coil should not be too big, it will not turn, it is about 2 × 1.5cm; the two sides of the coil scrape the paint, remember to scrape half a week while scraping, the copper wire must be in contact with both ends of the battery.
