ADJ Inno Roll HP Barrel stepper motor

[DJ Jules]

My Inno Rolls have hit that time of life when motors are starting to fail and the movement is getting a bit jerky (assuming it moves at all). On the face of it, the stepper motor in the barrel appears to be a common part. 42mm square x 32mm deep with a 5mm shaft and 6 pin/4 wire connection - used in 3D printers around the world! The complicated bit is that the motors are made with a variety of current ratings, internal resistances and torques and searching for the model number on the back of it brings up nothing.

Number on the back is 42BYGH237-C-15

Helpfully, the ADJ website shows 2 different stepper motors and doesn't tell me which one is for barrel, tilt or gobo/colour wheels. But the one that looks most likely to be the equivalent has a different part number listed 42BYGH003-C-16. This also comes up with nothing if you google it.

Does anyone know how to decode the numbers/letters after the 42BYGH to tell what spec I should be looking for - I can't see a pattern in the spec sheets I've seen?

That's the one that comes up on the ADJ Europe parts site. However, the part number isn't an exact match for what's there at the moment and it looks like it's a thinner model (which is likely to be lower torque). This one looks more similar, but again it's a different model number : https://djlightingdiscount.com/produ...2bygh311-b-20/

003 Vs 273 Vs 311 and then 15 Vs 16 Vs 20 in the suffix number. They've got to mean something, but I can't work it out from the spec sheets for the different models.

Ultimately I just need to know its going to turn and not burn out either the coils or the driver, but I have no idea how to work that out.

In case anyone else finds themselves in this predicament, neither of the motors on ADJ EU's parts website is the barrel motor One is used for the gobo wheel, gobo rotation and pan and the other is for the colour wheel.

I still have no clue what the spec is for the barrel motor.
