I was able to find the datasheet for the motors in my Power Wheels truck. I have it on good authority that all Power Wheels vehicles contain either a RS-550 or RS-755 motor. The motors are very different in physical appearance, so it’s easy to identify which motor your car has.

The single passenger F-150 that we’re using contains two RS-550 motors which, according to the datasheet, can draw 70A of current when stalled. Typical performance is around 9A, but is still much higher than I expected. I should note that I’m not quite sure precisely what I expected, but I’m a little concerned about creating a motor controller for something that drives so much current. I may take a serious look into purchasing a pre-fabricated motor driver.

It is also noteworthy that that RS-550 motor is actually capable of running on voltages as high as 14.4V constant. And while I have no immediate plans to upgrade the battery, it’s nice to know that we can unlock some serious potential for speed. I’m already fantasizing about hosting my own little autonomous NASCAR circuit on a quarter mile running track. But one thing at a time.
