Re: Sewing Machine Motor w/foot pedal?
As I said I have the KB 90/180 volt dc output unit. I want to run a 24v perm magnet motor. I contacted KB tech support and was told to turn the potentiometer all the way CCW before turning the motor

Dick: If there's a nameplate on the motor it will usually list the FLA (full load? amps) of the motor - HP or KW might also be listed on the nameplate.? From the FLA and the motor voltage you can

Re: Sewing Machine Motor w/foot pedal?
Thanks, Clark! I have one more question to ask. How does one determine the wattage of a dc motor if the seller doesn¡¯t know or is unwilling to find out. I want to find a 24 volt permanent magnet dc

Re: Sewing Machine Motor w/foot pedal?
Hi Dick - the resistor I added is different from the horsepower resistor - that has to be selected according to the ratings of the motor and the input voltage you use. There¡¯s a table in the user

Re: Sewing Machine Motor w/foot pedal?
I have one of these, noisy and not that powerful. I have been using a XD3420 12v DC 3000 rpm on my Unimat SL. It fits in no mods. Not as powerful as the scooter motors.

Works for me from UK. Searching for "775/795/895 dc 12v" brings up some suppliers of all three motors.

Re: Sewing Machine Motor w/foot pedal?
It looks like a range of small high power, probably high revving (no real figures given), motors are emerging from China. Ebay 363151138130 is offering three variants, although I'm not sure what the

Re: Sewing Machine Motor w/foot pedal?
Clark, Now I get it-it is the resistor that limits the voltage available to the motor. So even though my KB motor control is 90 volts the resistor used sets the upper limit. I am learning a lot on

You need the horspower resistor, I believe that tells the drive how to set-up some of its' electronic limits.

Re: Sewing Machine Motor w/foot pedal?
I use a 90v, iirc KBIC-120 controller to power a 36v scooter motor as well as a 90v treadmill motor on my small knee mill. I wired it so the same toggle switch that selects the spindle adds a resistor

Re: Sewing Machine Motor w/foot pedal?
It's been a while since I did a project using a KB drive, but I remember that some units could be run on either 120V or 240V.? When operated on 120V you got a 0-90V output, and on 240V you got a

Free is good. Also bird in hand V birds in bushes, etc. You will need to look for a 90 V motor, either permanent magnet (two wire) or with separate field and armature connections (four wires). I have
