Hello,
For example, I would like to use a
NEMA17 stepper motor for various handicrafts. Matching drivers. But I have problems with the current and voltage information.
I find the voltage for the motors to be 3 to 12 volts and the current to be 0.3 to 2.5 amps in the sales information at the large dealers.
And there are the well-known small drivers, such as DRV8825, right through to larger modules with multiple outputs.
For some of these motors I find information in the instructions from 3 volts up to 2.5 amps and fed with 12 volts in conjunction with a DRV8825. That doesn't fit, does it? Ok - with PWM you can also control high _performances_ with "small" chips. So it's still not clear to me how to interpret this engine information.
The providers may mean that you should set the driver to 3 volts if they specify 3 volts for the motor. Or is this the real voltage for the engine? In the test, one of my motors draws over 2 amps from the power supply at 3V DC when I "energize" a winding.
I guess I can't hang it on a driver powered by 12 volts? The same motor in my Mega This stepper motor matter is still a bit of a mystery to me.
What do I have to pay attention to now? Apart from dimensions, power, torque, etc. I'm just interested in very simple testing using Arduino and the usual small drivers.
