Looking to add a treadmill motor to a JD Wallace vintage bandsaw.

[jere]

The MC-60 as far as I can find is a PWM but that kind of stuff is above my pay grade. Like I mentioned it's a really common controller it turns out. There's even talk about it on the CNC forums and I guess there's mods for it. I wish there was a pin out for the controller that was on the mill I got gym motor off of, but unlike the MC-60 all the contols connected thru a single ribbon plug. Very pro and tidy. It also sat on top of a unit that is all choke/coils ? and the motor output went from controller board thu one of those coils then to the motor. Do you know what they are for? Speaking of eBay, there's a guy on there selling mill motors with what looks like the stock MC-60 controller with vid demos. In the demo there's a smaller coil like mine and he says" you don't even need this, very simple" he keeps saying.

I have no idea if this box I got is going to work long term but I like the control layout. And the use of a knob for speed means theres no memory or poking the control panel for speed control. But the box is plastic and has no mount tabs and looking at all these controllers they use the al unit they are built on as a heat sink so I don't want to drill into the box to mount for fear of drilling into the board/heat sink and it being enclosed like this is it going to get hot? Too many questions for a poor noob.......

I did a quick search for the mc-60, its definitely a pwm and are in lots of different mills like you said. was the choke part a donut with some windings around it? if so it is for limiting interfering "dirty" ac current frequencies. then let "ckean" DC frequency pass thru if the. DC motor can run without it I would suspect there to still be long term problems like shorter motor life maybe speed control and or power output. maybe someone else might chime in I don't know much on the subject either unfortunately.

as for mounting I would just open the plastic box up if possible. then find a spot on the extruded al heat sink that is out of the way. run a bit and bolt through the plastic and metal in the same spot
you might have some space to work with like this one


this is sort of how the other Taiwanese controller was mounted. the heat sink is bolted to half of the mounting box. I am planning to make a dust cover and bolt on a support to the galvanized steel sheet. the fan from the motor blew air over the board so I will add a small fan to replace it.
