Drill Motor used for RC Car

 

Instead of spending big bucks on one of those high power RC car motors Rabbithazen was thinking outside the box and used a Ryobi drill motor in his RC car. It wouldn’t make sense to go and buy a new drill just to harvest the motor but there are lots of ways to pick these up cheap. For example, most cities have a warranty depot where non-repairable drills with perfectly good motors are going into the trash.

"Here is my e-revo recently i tore apart my brand new 18V Ryobi drill. it was a direct bolt-on to the motor plate. i am running two 7cell NIMH packs. This motor does crazy wheelies with 3/4 throttle, full it lifts the back wheels off the ground onto its wing. after a full run this motor barely gets warm. It’s almost still room temp."

  1. you could blow the tires off with a three phase brushless motor.


  2. I remember using a motor from a battery operated vaccum cleaner (with dead batteries) to power my RC truck when i was a kid many years ago. It ran like hell… Much faster than with the original motor 🙂


  3. those 4.6amp cells look awsom, when i was a kid we could only get 2.2amps. i might have to start reliving my childhood as i have a 18v drill with a dead gearbox 🙂


  4. A 3-phase brushless motor is really impractical for this. The beauty of the DC motor is the tremendous torque at extremely low RPMs.

    Besides, what would he use for speed control? I’m not aware of any 3-phase variable frequency drives this small, and a custom one would be tricky to program from scratch. Do you know of any u-controller code for a variable frequency drive?
