garranaga Report post Posted February 6, 2019 (edited) Does anyone know how to reduce speed to servo motor on Juki 1508NH, I need to go dead slow. Jerry Edited February 6, 2019 by Wizcrafts Corrected model number to NH Quote Share this post Link to post Share on other sites
katit Report post Posted February 6, 2019 Depends how slow you need. In my case swapping standard 75mm motor pulley to 50mm was enough. If you need literally "dead slow" - need to use something like this: http://www.techsew.com/parts-supplies/sewing-accessories/speed-reducer.html Quote Share this post Link to post Share on other sites
garranaga Report post Posted February 6, 2019 katit Thanks for the link, I think your right. Do you know what size I should get? Quote Share this post Link to post Share on other sites
dikman Report post Posted February 6, 2019 That type generally comes in only one size. Quote Share this post Link to post Share on other sites
R8R Report post Posted February 7, 2019 "Servo motor" can mean literally dozens of different motors. There is no one stock motor for the 1508NH unless it's an actual stock Juki motor. We need details. You generally want to: 1) Have a motor with some type of slow speed control, either in a menu system or speed potentiometer knob 2) Have the smallest pulley you can fit onto your particular motor 3) Possibly add a reducer wheel like that Techsew one or similar. Those are sold all over the place. The one Keystone sells is of excellent quality, with nice sealed bearings - https://store.keysew.com/parts/sewing-parts/sr-2 Quote Share this post Link to post Share on other sites
