You don't specify which aluminum extrusion you're looking for.
The bracket is usually unaffected by the motor's length. It should work as long as the holes are spaced correctly. What is the make and model of your engine?
Selected User Reviews For Anndason Nema 17 Stepper Motor Mounting Bracket w/ M3 Screws (6 PCS)
That is precisely what I was looking for. I frequently purchase Chinese printers, and one of their favorite ways to save money is to use shoddy acrylic or very thin metal motor mounts. Because motors are typically used to move something like a belt or roller, they are under a lot of pressure to bend in the direction that the belt or roller is pushing or pulling on them over time. I had two motors on a cheap CoreXY machine just continuously heat up and malform some acrylic motor mounts. To keep the motors running, tensions had to be readjusted on a weekly basis. These are fantastic! br>br> They are made of 2mm thick metal that has been bent into an L shape. That would be fantastic in and of itself, because they are unlikely to bend due to their thickness. They went a step further, however, by spot welding two small triangle-shaped wedges in the corners. Without a lot of force, these puppies aren't going to bend anywhere! This item is extremely durable! br>br>On one side of the L bracket, four holes for mounting a NEMA 17 motor have been drilled. As a test, I mounted four of them to motors and ran them. All of the holes for the NEMA 17 motors were perfectly aligned on all of these. br>br>The mounting hardware could have included a wider range of short vs. long screws and nuts, but most of us have M3s, M4s, and M5s on hand. The motors went up without a hitch. They couldn't possibly have shifted in any way. br>br>On the other side of the L bracket, there are two long holes for mounting to an extrusion or frame. They're two long slots that make it simple to loosen screws, adjust the motor and belt belt tension, and tighten them again. However, because they have slots rather than distinct holes, they can turn or change mounting tension as the part wears. However, if you properly tighten the screws mounted here, you should have no problems. br>br>In conclusion, these are extremely durable and well worth the money if you plan on mounting NEMA 17 motors so they don't bend out of shape. On my Tronxy X5SA, I had to replace a few mounts. br>br>On your next build, I strongly advise you to use these.
A mount was required to position the Extruder Stepper motor at a 90-degree angle in order to accommodate a larger lead screw. I'm sure I could print one of these, but my printer is broken, so that's not an option. It accomplishes that goal and does so admirably. The only issue is that the original stepper motor location's screw mounts are slightly too far apart for the rails cut into the mount. Overall, this is a solid piece of equipment that comes in a six-pack. (Monoprice Select Mini V2) It does the job and looks good on a black machine.
These brackets are in good condition. With my machinist's square, I built and tested the squareness of the piece. The included hardware is the only gripe: br>br> Four M3-sized batteries are included in the package. The motor is mounted with 10mm countersunk screws, which are both the wrong head (holes are NOT countersunk) and too long for a standard NEMA17 motor frame; You'll be dealing with an extra 2mm of length. Get a 25- M3-package (or multiples) Motors should be mounted on these with 8mm dome, round, pan, button, or cap head screws (NOT oval, countersunk/flat, etc. ). Apart from this nitpick, these appear to be more than adequate for projects such as 3D printers, and are thick enough to withstand high-temperature environments. Motors that generate torque (e. g. , electric motors) , 0. 59Nm / 84 oz - ) in this category of size.
These move the motor far enough away from the Z axis that it can't be used. br>br>These are heavy welded mounts that would be ideal for a different application.
These are well-made, with gussets on both sides that allow a NEMA 17 motor to fit between them if you want to use it that way. br>I screwed the motor into place and tightened the screws. The mount was still loose, necessitating the use of a shim between the motor and the mount or the use of different screws. Washers should not be used with taper head machine screws, in my opinion. Instead of using them as shims between the motor and the mount, you should use them as shims between the motor and the mount. br>Overall, it's still a good buy!.
These were purchased for a project, and they fit perfectly on the motors. They're physically strong enough to go well beyond the motor's capabilities, but light enough that they won't eat into your weight budget. The inclusion of screws and nuts was a welcome addition.
Although the metal is already thick (3mm), the welded corner braces ensure that it will not bend. Ever. For the motor, the holes are in the proper locations. I couldn't have asked for a better set of mounts.
I used one of these as a replacement bracket for my 3D printer, and it's much more stable than the original. The only criticism I have is that the included screws were a little too long for my stepper, but the provided nuts served as a spacer, though the short set could have been a little shorter. It would be even better if someone made these with slotted motor mount holes to make fine tuning alignment easier, but since I couldn't find any, I had to make do.
