Members cdthayer Posted January 3, 2014 Author Members Report Posted January 3, 2014 Hi Jody, welcome to Leatherworker.net If you don't already have a Speed Reducer, or are not going to cobble together your own, then probably your best course of action to slow your 225 down is to contact one of the Dealers here at the forum. They will probably recommend that you consider a motor change to a servo. The cost savings of a SR instead of a servo would not be practical, if you have to buy everything new, IMO. In my case, I had the SR on-hand from an Adler machine. If you purchase either a servo or SR new, mounting instructions should be included to help you.

Members LoveToLearn Posted February 22, 2016 Members Report Posted February 22, 2016 Thats cool but where are you guys finding the tiny pulley for the motor? I have a Consew clutch motor with a 15mm keyed shaft and I can find nothing for it. I woud like a 35mm pulley with 15mm bore. The machine is a singer 111w-155 which i think the handwheel pullley is 3V. Any ideas where I can locate one of these mythical creatures? If it doesnt slow it down enough that way, Ill add a speed reducer. I already have an idea how to make one inexpensively. Quote
Members dikman Posted February 23, 2016 Members Report Posted February 23, 2016 I have 45 mm pulleys on my machines (I think that may be the smallest available). They came from the motor supplier in China, so I reckon a search on ebay should turn them up. They are 15 mm keyed, which appears to be a standard shaft size.

Did you notice a remarkable difference in speed and control by changing that pulley? Quote
Members dikman Posted February 23, 2016 Members Report Posted February 23, 2016 In my case I have servos and speed reducers on two machines and a servo and 8" pulley replacing the handwheel on the third. I wouldn't say that it's a remakable difference with these combos, but it is noticeable. (I figure it all helps). There is another factor, in my case - the settings in the servos affect the performance, if I set the max speed low then this also makes the lowest speed correspondingly slower. So lots of options.

Members shellbelle7 Posted March 16, 2016 Members Report Posted March 16, 2016 I am new here. I have a Singer 236 W 100 (post) that I bought from Red Wing Shoes, It has an elko multi phase motor and I rewired it to plug into our dryer plug in. It is very cumbersome to do so. Can I purchase a servo motor for this? If so I could move it inside to the workroom. I also have a econosew 2060E walking foot with a clutch motor and would like to reduce the speed on this. I am new to these machines and have been having trouble finding out how to oil them and clean the older singer up. Any suggestions would be much appreciated. Thanks. Quote

Your simplest option is to replace the pulley on the clutch motor with a smaller diameter type 3L pulley and a shorter v-belt to match the difference. The change from a 3" to a 2" pulley is 33% reduction in top speed. The larger the existing pulley, the greater the decrease will be with a 2" pulley. Measure the diameter of the motor shaft first to ensure that you buy the correct bore in the new pulley. If the existing shaft has a positioning key, make sure the new pulley is keyed as well. Sewing machine pulleys and belts are sold by all industrial sewing machine dealers I have ever heard of.

Members dikman Posted March 17, 2016 Members Report Posted March 17, 2016 As far as I know the "footprint" for mounting an industrial sewing machine motor is fairly standard (at least for every one that I've seen), i.e. 3 bolts in a triangular shape. If you have this configuration then a servo motor should be a straight swap, although you may need a different size belt too. This is the link to the manual for the Singer - http://www.manualslib.com/manual/522893/Singer-236w.html - should help with the oiling.
