This is an experiment that will show how a motor works
What you need
- A brushed motor
- 2 bearings that will hold the rotor
- Popsicle stick
- Hot glue
- Soldering iron
Step 1: Take Apart the Motor
Completely disassemble the motor including the magnets and brushes(the electrodes) and make sure that they are operable and in good condition. If not change the motor.
Step 2: Plate
Get a plate or similar to mount your motor on. Clean it to ensure strong glue bonds. Sand it to increase roughness if necessary.
Step 3: The Magnets
Cut two 1.5cm parts of the stick, then glue the magnets on the sticks. Place the magnets 2.5cm apart on the plate and glue them facing each other.
Step 4: The Bearings and Brushes
Use the rotor to position the brushes. Make a mark, solder wires to the brushes and glue. Position the rotor and bearings/supports, then glue in place. Be sure the brushes are touching the contacts on the rotor.
Step 5: Test
Use a battery/power supply to test the motor and and make sure the wires are not shorting out if your plate is metal. Once it works, you are done!
