Members Joniboo Posted March 12, 2020 Members Report Posted March 12, 2020 (edited) I have recently been in contact with a supplier regarding this motor (JK-563A-1) and was told it is not possible to remove the pulley! As I read this thread I got confused. Did you find it easy to remove the pulley? Could you share the measurement for the inner diameter of the pulley? Was it straight of angeled?

Members Constabulary Posted March 12, 2020 Members Report Posted March 12, 2020 (edited) Pulleys from Jack Servos are removable (I have two of em). The point is they do not supply smaller pulleys for this motor, so you have to modify a pulley with15mm straight bore. I guess thats why they say it is not removable. BTW why should it not be removable - some one assembled the motor and installed the pulley... so...

My mind almost could not comprehend it so I created a scenario where they welded it to the shaft because reasons So the shaft have a tapered shaft? So the straight bore pulley needs to be modified by a sleeve of sorts? Edited March 12, 2020 by Joniboo Forgot a question Quote
Members chrisash Posted March 12, 2020 Members Report Posted March 12, 2020 (edited) You could always design and fix the new pulley to the old one and just adjust the position of the motor to line up machine and new pulley You would naturally need to keep it balanced Edited March 12, 2020 by chrisash Quote Mi omputer is ot ood at speeling , it's not me

Some new and old motors still used them, and you can get them in a variety of sizes if that's the case.

Members jimi Posted March 15, 2020 Members Report Posted March 15, 2020 6 hours ago, Gregg From Keystone Sewing said: Is it a tapered bore pulley? No Gregg, it is a 13mm bore with a 2x4mm key way. I printed one out yesterday in two halves to avoid support material and time (and i am a noob at this...Lol..) and it works real slow and nice, BUT the needle positioner will give you a error5. So today after trying to figure it out i can only think that the chip is programmed to a certain time lapse?? it will trigger the error if the disk in the positioner takes longer to trigger the sensor ?? So it seems that a 50mm pulley Will work, I have just printed one and tried it. I dont know if a 45mm one will work?? So if anyone wants the Stl just say, but it is real easy to do. Quote
