Latest Copy of the "North Pole Motor by John Bedini"
June 2002

Goal: 4,000 RPM @ 22ma (is it possible with the given specs?)

Now: 2,085 RPM @ 86ma, 12v Battery
(139 Hz/4 poles)

(The coil in front is to read the frequency)

Testing a motor design from John Bedini, the "Simple North Pole Motor". Here is a list of parts that are in his diagram, and the parts that I used:

 

Parts	This Motor	John Bedini's Diagram
Diode	1N914	1N914
Coil Core	Welding rods	Welding rods
Main Coil Gauge	23ga	23ga
Trigger Coil Gauge	26ga	26ga
Transistor	MPS8099	MPS8099
Coil Width	1"	1"
Coil Length	1.5"	1.5"
# of turns on Coil	560	450 to 800
Resistor	Best in this one at 270 ohms	Default 680 ohms
Rotor Size	2.5"	2.5"
Magnets	6/8 Ceramic Round	Unknown thickness -5/8 x 5/8
Bearings	Vcr Flywheel type mount	Skate bearings?
Rotor Weight	~1/4 lb	Unknown

Differences to date:

1) These magnets are 1/8" bigger right now-- tried smaller Neo and Ceramic magnets.

2) I tried using several skate bearings with steel, aluminum, and brass rods.
The VCR flywheel technique produced less friction.
