If we had a controller for unipolor motors wouldn’t they work the same as a bipolor motor for a printer. I have access to way more unipolor’s that i do bipolors. Is there some other reason there is not electronics for the unipolors other that the bipolor’s i guess may be easier to work with.
Unipolar motors typically have less torque and efficiency, but can be used with simpler drivers. Since bipolar drivers are as cheap and readily available as they are today, unipolar motors have practically become obsolete.
But yes, if you get unipolar drivers with a step/dir interface, you could use them in 3D printers.
I am actually using the unipolors now but driving them in a bipolor state so the power is not near what it should be for the size of the motor. I need to look into making an interface to get the max power out of them.
If you have six-wire motors, you can use them either in a unipolar or bipolar configuration (and they should get an appropriate amount of torque). Five-wire ones can (should?) only be used as unipolar motors.
I did not know this, i figured unipolor was only using 1/2 the coils or not at full power as the other lines were not energized. I am using 6 wire steppers btw.
