And a note about steppers that look exactly the same but come from different manufacturers. as I found out the hard way.
You'd think that a stepper is a stepper is a stepper.
I wanted to do some experimenting with my Wanhao Duplicator 9 MK2 400's stepper motors.
I wanted to see how easy it would be to replace a stepper if one failed.
So, as a test, I removed one of the 2 steppers for the Z axis. (it has one one each side.
I took it to my 3D printer store to match it up with someone else, since its labeling didn't help.
I found a stepper that, physically, looked EXACTLY the same. When I say EXACTLY, I mean, it's clear that both were constructed in the same factory, right down to every form.
When I got home, I just plugged in the cable to test and. NOTHING but a hum!
It turns out, that while it has the exact same connector on it, it's wired differently.
I realized that Wanhao was probably trying to FORCE people to only buy steppers from them.
So, in the future, if one of those steppers fails, I'll disassemble both the Wanhao stepper and the one I bought and compare how the windings are wired up.
I have a strong feeling that I just have to reroute the connections to make it work.
Not all steppers of the same format, size or wired the same, even though they can look the same.

These are commonly used to control the throttle plate in the engines of air ccooled standby generators. Stand by generators are typically used to provide backup power in the event of a utility failure in both residential and some commercial applications. The speed of the engine controls the frequency of the output power. These stepper motors are used to control the throttle position in the carburetor or what's called a mixer when used with propane or natural gas. The controller maintains 3600 RPMs and thus maintain 60 hertz output of the generator. This stepper is operated actively by the controller in the standby system to compensate for load changes on the generator.

curious if you understand why several of my stepper motors have continuity on the 1st and 3rd pins, & 2nd & 4th? i have been trying to figure out why my z-axis is stuttering loudly, and was directed to check continuity of the two coils' sets of wires. I then tested a brand new Nema 17 and that one also tests irregular. What the Fluke? Figured i better test my y-axis, which is moving perfectly, and has regular, 1st & 2nd, 3rd & 4th order.

Great tutorial as always, but one thing i noticed is that at around the 12: 30 mark in the video (when describing the Full Step motor) the coils look like they are wound in the wrong direction to be giving the magnetic polarity shown. Great job though and keep them coming.

What's the difference between a stepper motor and a servo motor. Does a stepper motor have a maximum rotation of 360 degrees where a servo motor can keep going in same direction even when reaching 360 degreee.

How is the function of the stepper motor different from servo motors? If you wanted precision control, could you choose either types or does something else influence whether you need a stepper or servo?

Hi! Does the torque start decreasing if for example controlling stepper motor turns from the full step to half and eventually to micro step, on the cost of speed? Great videos by the way: D

I just took apart my fan to fix it last night. I don't recall using my phone to look anything up.
And then this video shows up in my feed. This is getting out of hand.

It has a very strong magnet, and strong magnetic field. MFM drives and floppy drives can send a radio signal about reading, writing or about the status of the software used.

Thanks!
Thats added a little to my knowledge, and cleared away a little of the mystery.
Clear concise, and to the point.
Couldn't be better. #.

This device by far is as advanced as any on Leos
Archimedes', Socrates, or Newtons discoveries or writings! Your explanation was perfect!

How does the stepper motor hold the torque? If you keep the voltage over the coil, wont this lead to a short circuit?

But why does the stepper motor stop once all the wires are connected to each other when no power is applied?

Fun fact: If the conditions on a stepper motor are right, you can get them to make FRICKEN MUSIC WITH THEM!

So if u use this with my wall counter I use to measure the depth on wireline Will it be more efficient
