For our drill motors, we made an intricate prototype cooling system (Though we're not using it because of weight issues):

We measure the motors to be 1 3/4 inches in diameter. When in the mount, 1 1/4 inches of motor was accessible. If you buy a copper pipe 1 3/4 in diameter, cut it in half so u get 2 semi-circle pieces of pipe. Then cut those pieces to be 1 1/4 inches long. Polish the inside and put some thermal compound on the inside. Then get a pipe 1 inch in diameter and solder the two end pieces you just made. Drill 2 1/2 inch holes 1 inch from the end of the pipe. Then drill a 1 inch hole in the middle and put a small muffin fan on the top so it’s sucking air out. This device becomes very cold and is a great way to cool off motors easily.
