starter motors are designed to only run for a few hours total in their life and only for up to 10 seconds at a time or they tend to overheat, look at the size of them, they are around 2 horse power and the size of a quart jar, the 2 horse power continues use motor that is in my garage is about the size of a water melon.
starter motors also tend to have very small soft copper brushes, instead of the larger carbon brushes, they can handle more current but they tend to wear really fast, but if the motor only needs to last a few hours then that's ok.
