View Full Version : Motor Controller Question

01-04-2013, 08:27 AM
So im trying to move two of thise motors:DC Motor Specification

Model: Faulhaber 2342L012 [DataSheet (http://www.specamotor.com/en/Faulhaber/motors/2342-012CR/datasheet_motor.html)]
Working voltage: 12V
No load speed:8100RPM
Nominal output power:17W
No load current: 75mA
Load current:1400mA
Gearbox ratio:66:1
Encoder Phase:AB
Encoder Resolution:12CPR

And im between this two controllers: http://www.pololu.com/catalog/product/707/specs vs http://www.pololu.com/catalog/product/708/specs

Ill connect it to the arbotix board

If these are the surplus motors that I think they are (using this gearbox (http://www.allelectronics.com/make-a-store/item/GH-2/GEARHEAD-USED/1.html) and often available on ebay), then those boards are both overkill. A plain L298 arduino motor shield will be enough (only get about ~1.7Nm torque at stall). Darsha is still using four of those motor with two L298 driver boards because I still have not gotten around to upgrading her chassis and/or drivetrain (many months overdue).

I been thinking about upgrading this motors for a bit, they are very slow, and make toonsss of noise... But still not sure which ones to get.. So ill probably start with this ones, i have this around my house: http://www.dfrobot.com/index.php?route=product/product&filter_name=motor%20controller&product_id=66#.UOcELm9QVQ0 probably ill use that then in the mean time.

Then when i upgrade the motors ill get a controller

Crazy loud... definitely the same motor/gearbox. There are four on Darsha; combine that with the thumping from the non-round rollers on her omni-wheels, and you have a recipe to make ears bleed. I've been wanting to replace her motors with some P60 sets from banebots, but their motors have some pretty hefty current requirements and I don't know how they fare with regard to noise (if anyone wants to fill me in, I would gladly welcome it).

Will the arbotix board run this motors? i think it has a 1A motor driver?

Since it uses more than 1A, you should use a separate motor controller. I like the ones from Pololu.
