Title: Good motors for a featherweight 30lb bot?
Post by: The Answer on July 09, 2014, 02:42:21 PM
I'm looking at the Turnigy AquaStar T20 3T 730KV/1280KV Water Cooled Brushless Motor so far but I wanna run it by you guys any suggestions are welcomed and encouraged. Main thing I'm looking for is fast and powerful pushing.

If you're looking for drive motors, you'll need some gearboxes to run with those.

Probably not a good idea to use a water cooled motor for combat. What motor you need depends on what its going to be doing, but the way you worded it tells me that your going to be using it for the drive. In that case, a simple cordless drill works well, look for the cheaper stuff or if you want to splurge on the good stuff, go with Dewalt. If your looking for a weapon motor, again, depends on what its doing. If its going to spin something, brushless, if its going to lift something, brushed.

My bad I should've said outright it was for drive motors I will look into cordless drills, and dewalt.

In fact, look on YT how to build a combat robot, and it's a 4(?) part tutorial showing how you can make a simple, cheap, fast combat robot, including a parts list and easy steps

if you have the money, go with dewuts. if you have less money go with a p60 or versa planetaries with a 775 size motor. if you are USA based, harbor freight drills are not a valid drive option. the pins fall out of the carrier plate on the 2nd stage.

I wouldn't use brushless in the drivetrain because of the delay between forward and reverse that happens when the esc tries to pickup the motor again after a direction change

Hmmm what would you use for a drive train @SKBT?

if I had infinite money, dewuts. I run versa boxes with 775s on 6s in my 30lb drum. I was happy with them.

2 DeWuts and a RageBridge from http://e0designs.com/ (http://e0designs.com/) will get you most of the way to a solid drive system.
