Re: Stepper Motor Codes

Also, what about the 4 wires? Ever seen a 4 wire unipolar stepper? I thought all unipolar steppers were 5, 6, or 8 wires? (Why don't you Google that and get back to me... I think this caper is a bit...

Re: Stepper Motor Codes

Meh. it's close enough in my book. If you need specific details on a part number not shown in that document, contact Minebea directly. That was the point to my "lecture". This is what engineers,...

Re: Stepper Motor Codes

I contacted the manufacturer before posting -- they're slow. My question pertained the the code used for the serial. And how is "g4vs" closer to "u" than "b"? And how is a four wire stepper more...

Re: Stepper Motor Codes

If you had said you "already contacted Minebea" and if you had even posted the name of the mfg in the initial post, I wouldn't have bothered to respond in the first place. I think you're full of it...

Re: Stepper Motor Codes

Believe what you want. I prefer "agile" to "waterfall" project planning, so I query multiple sources for the information I need simultaneously. They do love waterfall dev in aerospace, don't they?......

Re: Stepper Motor Codes

Honestly, beyond this post, I don't intend to address any further questions from you, wherever they're posted. your attitude is typically adolescent and unworthy of my assistance.

Re: best motor: high torque or high resolution?

currently i am testing what a manufacturer claims to be a NEMA 23 400step/rev 120 oz-in stepper. it is worse than my NEMA 17 42 oz-in sanyo. i have tried voltages ranging from 10- 26v and all current...

Re: Stepper motor to low curent not moving ...to high curent to hot

hi, i use sanyos ( or rather, still testing) mine are 9v, .85A i use 4983, they seem to skip less steps than 4988 (still not sure why) did you calibrate the drive current? when mine is almost...

(:P) i tested a new stepper (:P)

hello folks, i tested a new stepper ordered from a website (wwwonlinesteppers.com , its china i think). i was a sucker at their pricing (and i need some low budget steppers :p ) so just to share some...

Re: Stepper motor to low curent not moving ...to high curent to hot

Quotemy mottors do not spean and whene i raise the power it gets very hot and laud First, remove the belts to make sure there is no mechanical friction. You should be able to turn the motor with your...

Re: Stepper Motor Codes

As it's your hobby shop, can you measure these four wires? Unipolar motors have all four wires connected, on bipolar motors one wire has a connection to only one other wire, the other two wires are...

Re: Stepper Motor Codes

The ending g4vs is a customer kode. I.e for special axel, gear and so on. I know this because i work with copy machines and they use alot off the same motors but with different gears on. :-) So don't...

Help me control a stepper motor pleaaase

Hi, I've designed a product and I need to build a prototype which includes a stepper motor that mimics the control knob/jogwheel/encoder/dial movements 1 to 1 or close to 1 to 1. So when you turn the...

Re: Help me control a stepper motor pleaaase

I assume your second link should be [www.instructables.com] I think it only looks more jerky because the pointer is much bigger. A typical stepper motor has 1.8 deg step, they both look about the same...

Re: Help me control a stepper motor pleaaase

Without a microcontroller it'll be pretty tricky - is there any reason you don't want to use one? You'll need a quadrature encoder if you want it to work in both directions - a quadrature encoder has...

Re: Stepper Motor Codes

@Kenzu: Thanks! Excellent info and exactly what I was looking for. I heard back from the manufacturer yesterday and they refused to give me the specs because it was a custom order.
