Greg, I am using hybrid servos for my mill conversion, they work great, so far. They need to be tuned, otherwise they hum and their torque drops quickly. I am getting upwards of 270ipm on Y with 5mm screws and x25 microstepping. Don't have X yet. Can probably go higher still since I have not had one fault out even when I tried by tightening the gib.
Here's a short video, I guess their louder then servos, but not nearly as bad as steppers. https://www.youtube.com/watch?v=P4cvlaToqpY Here's a link to were I bough them. https://sutai.en.alibaba.com/product/60553941360-801999927/6A_12Nm_1_8_degree_nema_34_china_closed_loop_cnc_stepper_motor_kit.html Kurt On Tue, Jan 24, 2017 at 4:54 PM, Greg Bernard <[email protected]> wrote: > Seeing the discussion of servo vs. stepper solutions come up once again I > wonder if anyone has had experience with these: http://www. > automationtechnologiesinc.com/products-page/nema34-closed- > loop-stepper-motor-system-hybrid-servo-kit/nema-34- > hybrid-servo-motor-kl34-8n-1000-rated-torque-1128-oz-in > They are only step/dir but they are being used in both Tormach and Shopbot > machines which leads me to believe they are a cost-effective > middle-ground.Any thoughts? > +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ > ++++++++++++++++++++ > "Anyone who believes exponential growth can go on forever in a finite > world is either a madman or an economist." > -Kenneth Boulding, economist > Corporations are NOT people and money is NOT speech! > ------------------------------------------------------------ > ------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, SlashDot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
