Hi, everybody,

I have one motors and one H bridge, and I want to use a second parallel motor with the first one, and connect it to the brodge directrly.
Would I, add another Bridge, or can I connect this second motor directly ro this bridge.

Think you!!
 

If the bridge can supply as much current as the two motors would dissipate worst case, then you can put them in parallel.
If not, you have to add a second bridge. Connect each motor to a power supply, and measure the current that goes through them.
Add the two measurements together, and see if its under the max. current threshold specified in the datasheet of the h bridge.

While it does depend on the average running current, I would say the initial inrush current would be just as important. As a general rule, multiple the average current by 10 to guess-estimate the inrush current, then multiply by 2 [for 2 motors] - can the transistors handle the peak?
 

I can't really talk about specs,since the OP hasn't given anything to start with.
