Motor for kluge

Thank you Kayprint for the info. I already took my motor to a shop and it is totally shot. It was the original motor on the press. As for feeding it manually, I don’t need to use the grippers. My concern with sticking a new motor on the kluge is that it will run too fast to be manually fed. So I would love to hear if anyone has any experience with this or recommendations for a new motor I can put on this press. Thanks again!

Grainger probably carries a comparable model, but yeah, they tend to run a little fast— the speed gets it over the hump of turning the wheel without drawing too many amps. When I run mine too slow, they just come to a stop, but my motor mount is on a worm gear to control the speed by adjusting tension on the belt into a v-shaped pulley.

I remember researching into variable frequency drives, which will adjust provided current to the machine in order to alter the speed? See this / search for that term on Briarpress:

my kluge has a old motor, most likely an original, it has a variable speed dial that I believe cuts the power to the motor, I hand feed mine every once in a while, you can disconnect the feeder then hook it up in a couple of minutes to use it again. I always remove the grippers before hand feeding.

I suggest you consider installing the new motor and variable speed controller with what is sometimes called a jack shaft, an intermediate shaft with two pulleys on it. One would be a stepped pulley with the largest step the same diameter as the pulley on the motor and at least two smaller steps, perhaps 1/3 and 1/2 the diameter of the largest step; the other pulley could be the same size as the motor pulley. With this setup you would be able to reduce the speed of the press to 1/2 or 1/3 the full speed of the motor, or run the press at the full speed of the motor. The speed reduction of the stepped pulley also increases the power of the motor by double or triple, depending on which step is selected, so that the smaller motor would be able to overcome the dwell resistance during printing.

what kind of power are you using, 1 or 3 phase, volts?
do you have the variable speed drive pulley on a movable motor base?
please either post or send some pics of the motor and pulley, and a close up of the plate on the motor.
a slower rpm motor is possible depending on what you are using.

Hello sofiaprints, I’m not an electrician but we have several old Kluges here. Some have their original induction motors which provide lots of tork to get the beasts moving quickly, and some have replacement motors. I have posted picks of the motor label and the motor/pulley. You can see that there is a little crank to move the motor/puley forward to increase speed and back to decrease. This system will slow the press to a crawl and gives a pretty good top speed.
There may be better options, I don’t know.
These presses have the autofeed system removed and they run backwards. By running the press in reverse the grippers have the correct timing for hand feeding. I’m not sure if you could do that with the autofeed still attached.
Hope that helps.
