I learned more about these stepper motors in the last eight minuets than I learned in the last eight years from other sources! Thank you very much for this!
Really nice. I was wondering about why an unipolar 5 wires could not also be a bipolar 4 wires by not using the common middle coil wire.... now I know that this is exactly what an hybrid is! Many thanks. And it is quite clear. I will definitively check your other videos as soon as I have time :-), you got me!
nice work. cleared up a whole lot of chaos in my mind. unfortunately the music has compensated for it by scrambling my mind and making me want to start a southern rock band
According to my experience, bipolar stepper motor drivers can also be used to drive unipolar stepper motors. Just connect the motor to the bipolar configuration and the center tap wire to ground.
Excellent, answered so many questions. Just one question...Does bipolar vs. unipolar mode use more power? It seems to me that it wouldn't since you're only energizing one set of coils at a time in bipolar mode.
Very helpful and clear video, many thanks. What is the soundtrack? It's very chill and it might be nice if you gave a credit to the artists in the vid description...
Once again your video was very helpful, I was able to get a 5 wire Nema14 motor working properly with A4988 drivers, My only question is because I am not using the centre tap, does the motor have the same holding torque in Bipolar as it did in Unipolar?
Now that I have easy driver / not so easy.I have a hybrid stepper, numbered all leads but which pair is a coil? One way motor hummed the other ran one way continuously no code yet?
Much thanks to you .Tutorial is very good. I have connected 2 stepper motors ( one in each port of arduino shield. I tried to spin each motors r( one at a time ) .It is ok.. What is the code to spin both motors at a time Request your help.
Nice video At 3:12 - what do you mean by a free wire - do you mean just any piece of wire without being connected to anything. ? how can it energize when not being connected to anything ? Where is the other end connected to ? Appreciate a reply.
Make the diagram of Bipolar 2 coils, 4 wires. Now, add a middle coil wire to each original coil, that makes a unipolar 4 coils, 6 wires. Join these two middle coil wire you just added to make a single wire, that is an unipolar 2 coils, 5 wires. Now, if you do as if these added wires were not there, you are back at the initial diagram, a bipolar 2 coils, 4 wires.
