Hi There!
I need to drive this motor (see attached photo), with an Arduino Mega.
Im not sure what hardware I could use. Can you provide a hint on what to use?
I can't find the voltage required. Also the wiring...
Looks like there are 2 windings (2 poles each winding) and the cables are parelled in groups of two, but the blue wire is on its own instead of a pair... Why?
Any help on this would be appreciated!
Thanks
Find out more and measure the resistance between all the wires. Rw should be 0.72 Ohm for a single winding. For Iw of 1.9A a voltage of at least 0.72*1.9 = 1.4V is required, more will be better. A current controlled stepper driver is required.
A hybrid stepper motor will have a common (blue?) wire for all windings, 5-6 in total, with a positive and negative wire for each phase in unipolar mode. In bipolar mode the common wire is ignored and both (+ and -) halves of the windings are used in series, of double Rw.
Ok, I read that this was a bipolar motor but I can't really tell
Given how those wires are connected in pairs (all but one) in the current socket does this give you a hint on whether they are unipolar or bipolar driven right now?
Thanks
Try to understand what I wrote. A true bipolar stepper has 2 wires per phase, not more except for possibly a shield wire connected only to the case. Hybrids have more wires and can be used as unipolar or bipolar steppers.
Mmm Im starting to get lost now as checking these photos again (that I took like 1 yr ago at my client's facility, so I don't have this motor with me now), I see different colors getting out of the motor than those wires getting down to the plug, so there's probably something in between. I need to go check that again in person.....
Thanks!
