Id say so yeah, there quite powerful and high speed, I think some are around the 1hp mark. A lot of people who build spinners started of with car fan motor powered weapons
I've never used car fan motors but they'd be infinitely better than a drill motor.* If I remember correctly, some of them can chuck out close to 1hp (which, for comparison, is what a Bosch 750 produces). they've got nice thick shafts as well thus minimising the risks of bending from impacts.
*(NST uses a 24V drill motor but that's one of the good quality Dewalt drill motors that are far superior to run-of-the-mill drills)
EDIT: What Dave said
That's a really neat idea, I'll have to see if we an get hold of one....
This is a spin-up test of Tony Booth's robot DragonStrike, using a car fan motor from a Ford Mondeo. Cost him £5 out the scrappy:
Couldn't find any decent footage of DragonStrike fighting, but The Toonimator uses a similar setup and is very effective:
Just to give you an idea of what potential there is
Looks like we'll be making a trip to the scrappy then!
Just to confirm, are we talking about the motor that drives the engine cooling fan in most FWD cars or the motor that drives the cockpit air vents?
engine cooling motor
Cheers!
considering my 24v nimh pack has for some reason decided to die on me, I'm looking at lipo. what do people use for a voltage cut-off in the robot?
Damaging the writing of your nimh pack might have something to do with that. In that case I would think twice about moving to lipo considering the higher currents involved.
Anyway back to the question, most people don't. Just over size the pack and charge after every battle.
