*Background info:
Hi, I am a machinist and I wanted to convert my lathe to variable speed. I Have been researching the idea and have come to some conclusions about what I need, but I do not have a full knowledge of how to do it.
I have obtained a broken treadmill and confirmed the motor works and is in good condition. (Pictures below)
-Treadmill motor- DC 90V, 15A, motor with 4800 rmp.
-current lathe motor-AC 110V, 11A, 1680 rpm motor.
I am planning on using the belt system to keep the max rpm under 1700.
It is mandatory that I be able to reverse the motor.
This is a list of thing I think I need: Bridge Rectifier, ON-OFF-ON switch, Variable speed switch (Link).
I did my best to make a circuit diagram of what I was thinking (Below).
*Questions:
1- Am I not incorporating some part that I need?
2- Should I put the on-off-on switch in region 1 or region 2? (diagram)
3- Is the bridge rectifier positive/negative specific?
4- If the rectifier is positive/negative specific is there anything I have to do different to be able to place the switch in region 2? (On DC Current)
5- Is there another type of hardware to use instead of the harbor freight router speed controller?
6- Do I need to take into account any other factors?
Thanks for your help!
