11-21-06

  • Assembly
  1. Glue mirror onto base
  2. Put magnets into grooves
  3. All magnets should be south facing in
  4. Use paper to shim the magnets
  5. Position magnets on rotor
  6. Rotor magnets are also south in
  7. use a little tape to keep the magnets from wobbling

 

  • Testing the motor
  1. Make the motor balance well before putting it in the light
  2. you should be able to make it turn by rotating it 1/2 turn and letting go
  3. Do not spin it real hard, that doesn't really tell you anything
  4. When you get it to balance smoothly, put it in the light
  5. if it is balanced, you should be able to get it to start in the light without turning it yourself

 

 

  1. if it does not work, you need to figure out what the problem is and solve it.
  2. Below are some common problems:

 

  • Balance is a common problem.
  1. Turn it 1/2 turn and let go
  2. If it falls, you can add weight to the highest part of the circle
  3. Add solder, made of lead
  4. don't add steel like nails, because they are made with iron, attractive to magnets

 

  • Magnets out of position is a common problem
  1. The magnets have to be firmly and accurately placed
  2. If they can wobble out of place, they will
  3. When they go out of position, it is never the way that you want
  4. Add paper to the base magnets
  5. make sure the base magnets are straight up and down
  6. make sure the magnets are all south facing in
  7. add a little tape to the rotor dowel to keep the magnets from flopping around
  8. the front dowel magnet should be over the frontmost base magnets
  9. the rear dowel magnet should be over the rear pair of base magnets

 

  • Solar cells not wired correctly is an occasional problem
  1. Make sure you have continuity between each of the pairs of cells
  2. make sure you do not have continuity between adjacent cells
  3. if your continuity is off, you may have to either rewire the wrap wire connections
  4. If your cells are connected to the adjacent cells, you will have to reconnect them to the oppposite cells.
  5. If a tab falls off your cell, you will need to have it soldered back on. Ask for help.

 

  • If it still won't run
  1. If everything above is correct, and it just wobbles back and forth try this technique
  2. neatly cut one pair of wires from a pair of cells.
  3. Resand the ends
  4. Solder the ends onto the opposite tab they were on before
  5. Ask for help if this doesn't make sense.

 

11-20-06

  • Rotor
  1. Solder cells together
  2. Solder each wrap wire to a pair of cells
  3. Drill hole in end of post
  4. Put small brass nail in hole

 

  • Assembly
  1. Glue mirror onto base
  2. Put magnets into grooves
  3. All magnets should be south facing in
  4. Use paper to shim the magnets
  5. Position magnets on rotor
  6. Rotor magnets are also south in
  7. use a little tape to keep the magnets from wobbling
