A Hall effect magnetic sensor switch has been enabled to serve as a motor control and current switch.
This makes all of the elaborate electronics for low power pulse motors unnecessary. Therfore we have an access to motor systems without large cash outlays.
The only other component is an LED to direct excess energy from the coil voltage collapse back to the battery. Which saves 10 to 20 percent of energy use.



The circuit works with a 12 volt lead acid battery.
This will work only with 15 miliamp or less motors with eight poles in the rotor disk.
My other main project is a transistor switched coil that has no moving mechanical parts. The output over input wattage ratio is 20 to 1. My goal is to place that circuit on one of my pulse motor circuits to see what happens.
I have been trying to get my camera avi video of a motor running to play on my webpage without success.
