I have an Arduino Uno , and a H-bridge L289N, and i need to use an old printer motor for a project. I red online that the H-bridge can only handle 36V, but the input for it is 12V. What am i missing? How can i ( if i can ) connect the whole thing? I also have a separate external old power charger that can provide 42V, 1.5A. Thanks!
What kind of motor is it (DC brushed, stepper, BLDC)?
There are other components on the module that cannot be stressed past 12v.
It is a EM-313 stepper motor
So basically the best i can do is to power the motor with 12V? Maybe i can power the motor full power directly with the external charger and control it with the H bridge in anyway? Thanks a lot!
Look at Pololu for stepping motor drivers.
So there is no way i can use the L289N with this motor right?
Thanks again, i'll look into it!
You can use the ancient technology L298 as a stepper driver just like you can use a frozen frankfurter as a hammer. It may work, but not for beans.
Get a proper stepper driver from someplace like Pololu like @LarryD posted.
ok thank u!
Robin2's stepper basics tutorial may be of interest.
