Hi Toney, Thanks for the motor controller system! In fact I have also the same motor and a different controller , PWM unit. I also intend to controller the capacitor in my future mag loop! I would like to suggest few things I intend to do. 1. Instead of the switch for forward and revers , I will use two press buttons, this will be easier to tune! 2. I will use a simple RF probe in the vicinity of the Loop and connect it to a micro amp or milliamp meter to indicate the field strength so I can tune for Max radiation. 3. I will use decoupling capacitor across the motor. 4. I will feed the DC to the meter via some RF chokes to prevent RF getting in to the meter! .......... I intend to do the same to my future mag loop antenna! Please use my suggestion at your own discretion, disclaimer observed! Kindest Regards! 73! Leonard Fernando. 4S7LF. Srilanka.

Have a good buying source for the motor and controller you have there? Very nice!

Seems like variable air gap capacitors without stops in the rotation action are hard to come by.

Good job.

Great video ! Thanks for posting ! Could you comment on the controller board ? I am hoping to make a similar capacitor controller but was going to use simple DC on/off and reverse polarity. The controller board is provides pulse width mod control of speed ?

It'll be interesting to see this develop. Will you keep it manually controlled or try to work it into an automated system?

Please share the motor part number. And details of the controller.
