Work

[husein06]

Hello,

So I have an Arduino Uno r3 and deciding on purchasing these motor kits http://www.parallax.com/Store/Accessories/MotorServoControllers/tabid/160/List/0/SortField/4/ProductID/587/Default.aspx?txtSearch=ball+caster

Would they work with the SN754410 motor driver ?

and will these batteries work with the motor?

Thank you

Motor spec: Stall Current: 4.8 A

Driver:

Spec: a peak current of 1 A per channel

Motor current much greater than driver current = smoke.

You need a H-bridge driver capable of at least 4.8A

Tow of these would work for those motors:

Hi,

Would they work with the SN754410 motor driver ?

The motor has a no-load current of 0.27A and a stall current of 4.8A, but no mention of a realistic load current, so maybe it will, maybe not, but I'd go for at least a 2A driver and then add over-current protection to keep motor as well as driver safe.

and will these batteries work with the motor?

Yes.
