Dual Shaft 0.9deg NEMA11/14 Steppers?

Post by ray_parkhurst »

Does anyone know of a source for NEMA11 or NEMA14 stepper motors with 0.9deg steps and dual shafts? In NEMA14 size I can find 0.9deg models, and dual shaft models with 1.8deg, but not dual shaft 0.9deg. In NEMA11 I can find dual shaft models, but not 0.9deg models. Does anyone know of a source for these elusive beasts? I have a couple of NEMA14's with 0.9deg and dual shafts, but they are OEM branded from China, and I can't find the original maker.

https://gemsmotor.com/nema-14-stepper-motor says "GEMS Motor offer two product lines of NEMA 14 size (35mm square) stepper motors, 35HSM28 with 0.9 degree step angles (400 steps per revolution) and 35HS20 with 1.8 degree (200 steps per revolution) . Each product line has single shaft and double shaft motor versions." But I cannot make sense of their table. Perhaps inquiring of the company?

Brilliant! Thanks. I really like the CNC site. Good pricing as well.

How did you locate those? I've searched and searched.

Google search on nema14 "dual shaft" "0.9" , with the quotes.

For me the buildyourcnc.com hit turned up as #10 on the first page.

The buildyourcnc.com page also turned up on first page using search at duckduckgo.com .

All credit goes to beginner's luck. Mostly I just wanted to get some impression of what the marketplace looks like!

Hi Ray,
at nanotec could possibly get some. This company also supplies OWIS with stepper motors.

I've seen a few nanotec motors in wafer probing systems, and they are very nice indeed. I investigated their flat motors at one time when I was trying to build a motorized z-stage. But looking at their US website, they don't seem to offer 0.9deg steps in NEMA 14 size, only NEMA 17 and 23.
