Proposed Circuit For Treadmill PS and Speed Control ----> Need Help Refining Ckt.
I would like to build a power supply and speed controller for a typical 0 to 130vdc treadmill motor.
I have found and complied the following schematics into the final circuit I would like to build.
Attached is a PDF file of this schematic
I am capable of designing, printing and etching my own PCB's.
My over-all knowledge in electrons is limited. I have a very good understanding on electronics.
I mainly build per-designed and proven circuits.
I understand all the components in my design and how they work.
What I am lacking is the skill to refine this design, add to, add enhancements , delete from, or substitute components. Would also be nice to know if I made any mistakes here in actual design and/or concept.
I would be very appreciative if someone could take a look at this schematic and comment on it.
This is basically three schematics complied into one. There is a simple and basic bridge rectifier, a simple 555 based PWN control, and a simple low voltage section. The low voltage section is actually copied from All About Circuits it is a schematic of a MC-60 treadmill controller prepared by Tom Rollins ("trolley1").
Again, please take a look and feel free to offer any suggestions.
Thanks
NOTE: I have revised the Schematic and it is to be found in a later thread.
