Simple brushed conventional motor for only $3.99 each! Sold in classroom sets of 10.
If you buy 2 sets or more you get free RPM measurement attachment – your students will be able to compare the speed of their motors.
Buy 4 sets and get in addition free Rapid Assembly QuikLock Kit #12 (so you can compare and see why it is really much better!)!
Please note that while this is the least expensive kit it is not the easiest motor to build as it requires a lot of accuracy in balancing the coil and stripping off the insulation. They are also not very stable and require frequent cleaning. Practically nothing could be attached to these motors and no experiments could be performed besides the basic speed measurement.
Reed switch motors are easier to build and understand how they work. They have a proven record of working every time without any struggle.
