H bridge 2 parallel motors Hi, everybody, I want to add a second motor to the X motor. I want to put them in parallel, when I command one, the second is also commanded!! Can I connect a second motor in parallel after the stepper driver. Or must I connect the command of arduino to a second stepper driver, and this to a second motor. https://reprap.org/forum/read.php?1,253812,253812#msg-253812 Mon, 14 Sep 2026 02:29:51 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,253812,253877#msg-253877 Re: H bridge 2 parallel motors https://reprap.org/forum/read.php?1,253812,253877#msg-253877

With two motors and one driver you cannot get max speed and torque out of your motors.

Depends on how much current you need. If the driver can spend enough for both, it works. Typically Pololus can't max out steppers anyways, it's always a matter of sufficient torque.

That said, one can run two Pololus in parallel, too. Apply the same Step and Dir signal to both and they should behave identical.]]> Traumflug General Fri, 11 Oct 2013 08:53:19 -0400 https://reprap.org/forum/read.php?1,253812,253836#msg-253836 Re: H bridge 2 parallel motors https://reprap.org/forum/read.php?1,253812,253836#msg-253836 jkoljo General Fri, 11 Oct 2013 05:44:17 -0400 https://reprap.org/forum/read.php?1,253812,253832#msg-253832 Re: H bridge 2 parallel motors https://reprap.org/forum/read.php?1,253812,253832#msg-253832
Exactly!!

Think you so much!! I just need to put a radiator on the stepper driver!!

Thnik you!!]]> chik General Fri, 11 Oct 2013 05:28:09 -0400 https://reprap.org/forum/read.php?1,253812,253830#msg-253830 Re: H bridge 2 parallel motors https://reprap.org/forum/read.php?1,253812,253830#msg-253830
