I would like to acknowledge the help and support of the following people:
ALL THE PEOPLE AT BANKSTOWN TAFE THAT WERE ASSOCIATED WITH THE PROJECT.
THIS PROJECT WAS DESIGNED TO ALLOW STUDENTS TO PRODUCE A WORKING MODEL OF AN ELECTRIC MOTOR.
I HAVE MADE IT SIMPLE ENOUGH TO PRODUCE AND THE PROJECT ALLOWS FOR STUDENT CHANGES AND ADAPTIONS AS
REQUIRED BY THEM.

|
Here are the measurements of the base and end plates used in the original version.
|
PRODUCTION
|
Use blocks of wood or angle pieces
To mount the ends on to the base.
|
|
|
Align the two end plates that will be used as bearings, so that the holes are straight and level. Otherwise the Pipette will bend causing friction with the glass tube.
|
|
|
Mount the magnets onto their supports. Use blocks of wood, angle pieces or any other means.
|
|
|
Using a tube or beaker approximately 100mm dia wind a coil. Keep the coil tight. Remember the more winding the more efficient it will be.
|
|
|
Remove the winding from the tube and use tape to hold it together tightly. Make it as tight as possible.
|
|
|
Cut two strips of brass or copper sheet so that it nearly covers halve the glass tube.
|
|
|
Separate some of the wire coil so that a hole appears at each end and shape the coil so it is oval or rectangular. Pass the glass tube through these holes and attach with string tightly.
|
|
|
Cut two strips of brass or copper sheet so that they nearly cover half the glass tube.
|
|
|
Cover one end of the glass tube with “Heatshrink Tubing” about the same length as the strips.
|
|
|
Solder the end of each coil to one of the brass strips
|
|
|
Mount the strips over the heatshrink tubing with more heatshrink tubing.
|
|
|
Pass the pipette through one end plate and insert the glass tube armature.
