Suemi Report post Posted June 4, 2010 Does anyone have an easy way of slowing the motor down on my Machine? I just purchased a 211W155 for sewing leather which seems to do that job well but it goes way too fast. It's either sewing like it's posessed or off. I need more response kind of like a throttle if you will. Is there any way to get this done? Thanks, Rich Quote Share this post Link to post Share on other sites
TwinOaks Report post Posted June 4, 2010 YES! It is entirely possible to slow down the machine to more manageable levels. That is one of the main things to take into consideration when setting up a machine to sew leather. It is commonly accomplished by the addition of a speed reducing pulley, and swapping to a DC servo motor instead of the existing AC clutch motor. The clutch motors get their torque from higher rpm (usually wide open throttle), while the DC motor is able to supply the torque at crawling speeds. The pulley installation further reduces the speed and increases torque. Click on the sewing machine supplier ads at the top of the page, then look for them on their websites. Another way to reduce the speed is with a larger fly wheel/balance wheel. Quote Share this post Link to post Share on other sites
Suemi Report post Posted June 5, 2010 (edited) I just checked them out and it seems pretty self explanatory. Would I be able to use the pedal built into my table though? Or would I have to use an external pedal? Thanks for your help. Rich Edited June 5, 2010 by Suemi Quote Share this post Link to post Share on other sites
TwinOaks Report post Posted June 5, 2010 The pedal is connected to the motor via some kind of linkage. All you'd be doing is moving the linkage from one motor to another when the motor gets replaced. You may have to adjust the length of the chain, depending on the positioning of the motor's switch, but the pedal should be the same. Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted June 5, 2010 The Singer 211 is a better machine for uph or canvas than leather do to the small flywheel that makes it harder to slow down. If you put a standard DC Servo on it you'll find you'll still be running to fast so then you'l have to add a speed reducer ok so now your over $225.00 I just wanted to let you know that we have a DC Servo with a builtin reducer that will slow your machine down w/o any problems for less $ and bolts up to the standard 3-hole standard mounting.
