Thanks for replying Mark.
I didn't realize anyone responded as the forum is being buggy and didn't receive any notifications. But, I have to admit the forum is running lightning fast now.
I fixed the 317 overheating issue. It was a bad solder joint one of the resistors.
I am getting 24V @10mA to the LM317 and 5.2V to the driver IC.
At the stepper I am getting 24V @75mA, Which is obviously too low.
Other info I should have included:
- Type 17PM-J034-P2VS
- Minebea Co. LTD.
- Part# FH5-1043
- 1.8 deg 200 steps/rev when full-stepping
- 2 Phase @ 2A per phase
for the 17PM-J series.
When I first bought these motors and started digging for information, I concluded these were bi-polar, now I am beginning to think they are uni-polar..
Any feedback is very much appreciative.
