Tamiya Twin motor gear box

Hi guys 

I have a question 

Does the tamiya twin motor work with the L293D Motor Driver IC

I am going to connect it to a picaxe would it work.

The motors stall current is 2.1 amps can the motor driver handle that?

I looked it up it says it can only do 1amp per a channel. Does it still work?

Okay, it may not work for long (max runtime I have tried is ~5 mins), and it WILL damage the motors, but it will work. The driver will drive the motors, and thus far in my experience the motors have been the only things to get hot (the driver is supplying more voltage than intended for the motors, and I have never let my motors stall, or even get close). As a long term solution your answer is no; if you are looking for something to test on your answer is yes, but you want to get the replacement motors for Pololu as soon as possible. I am using PWM, and going no higher than a value of 50 to drive the bot, which from my understanding is going to slightly lessen the stress on the motor driver, but from the heat on the motors after 5 minutes of run time I wouldn't trust this at all for a long term soluition.

Another suggestion, since you seem to be a beginner (much like me) is to work on reading the datasheet for your motordriver. This will list the maximum current recommended/allowed for the specific chip in your application. If the max current is less than the stall current for your motor (+ a few % to be safe) your motor/gearbox is incompatible with the motor driver. From all the reading I have done you will not find a good motor driver for this motor/gearbox combo.

With that being said all previous posters have much more accurate information than me, I'm just trying to provide an opinion from a complete beginner that is experimenting with a similair setup. I am driving Tamiya tracks just fine for short distances with a 1A motor controller, and have not had an issue yet other than motors getting hot for my ~5 minute test.

"the driver is supplying more voltage than intended for the motors"

How do you mean? The logic 5 volt voltage is separate from the voltage the motors getting. In other words: those l298 drivers has 2 different + voltage inputs. so I don't see why they should get to much volt.
