Instead of burning out the FA-130 motors that come with the Tamiya gearbox sets by running them with a greater voltage than the 1.5V nominal the datasheet recommends, I thought I'd look around to see if there are any motors that are drop-in compatible but rated for a greater voltage.
The hardest thing is finding one that has the same physical dimensions as the FA-130, so that the replacement fits well into the pre-fab Tamiya gearboxes. It looks like there might be some out there, though, possibly even available on surplus. F(x) -130 seems to indicate motors with identical dimensions, with the (x) being some sort of indicator of voltage rating.
A test done at Pololu appears to prove that running the motor a bit over-voltage does result in considerably wear. If I'm going to increase the stress in the Tamiya gearboxes over specs, I want to try with a higher voltage motor, and cross my fingers that the gears will be up to the task of the extra torque.
But I'm still on the hunt. Can you help me find a motor with identical specs to the ones that come with the Tamiya gearboxes, with the exception of a higher voltage rating? The dimension details of the FA-130 can also be found at Pololu. Thanks!
