Title: Practical motors?
Post by: Sylvestre on July 28, 2011, 01:44:52 PM: Would these motors (located in the following link) be practical for a robot that uses tank type treads? It has to have enough power to get over rubble, stairs, etc.

With more info I can not really say if this motor is practical for your application.

cannot be used mounted in reverse in a dual motor configuration.

...unless you plan to loose the one way clutch on the sprocket mount, and use your own fixed sprocket... ;)

This motor says its capable of rotating clockwise or counter-clockwise. This would solve my problem, right? Will 2 24 v 400 watt motors be capable of providing with A LOT of torque and will it be capable of going 8 mph?
