New Z Stepper
Posted: Sun Aug 09, 2015 3:21 am
So I have one of the old versions of the Z-stepper - one of the ~30 ohm models, that I felt needed to be upgraded.
I went on the search for a good replament, and also read the research ED had done on the stepper in his printer, but didn't care for the physical size he used as his solution.
so here is what I found. Busheng 17hd40005-300N and seems to be pretty widely available from many offshore suppliers its made by busheng motor in china.
its about 10mm taller then the current stepper. (measures out at 41.5mm) and uses the same jst connector so it should be plug and play
got mine shipped to me in 6 days from china.
(note: not plug and play, pins 3 and 4 are swapped)
will install it soon....
Specs:
2 phase
Screw : M8
Diameter: 8mm
Screw length : 300MM
Model: 17HD40005-300N
Step angle: 1.8°
Rated voltage: 2.4V
Rated current: 1.5A
Phase resistance: 1.5Ω
Rotor inertia: 57g.cm2
Holding torque: ≥420mN.m
Height of motor: 4.2cm
Winding inductance: 3.2mH
