I'd like to bypass the motherboard on a treadmill. The motor is a 90 volt DC. I suppose I need a converter and a rectifier. Any additional help would be great. My email is 238 [at] bellsouth.net Lee..Thanks

 

you probably need to define this better. the motherboard is basically DC drive, if you are to replace it with a "converter and a rectifier" you will be replacing with just another DC drive... so not sure what you are trying to do here....

 

What do you mean? do you want to supply energy to that motor always? are you looking for a 90 VDC power supply? please try to be more specific.

Good luck,
