04-02-14: I used a Himax 2025-3200 inrunner for power. Here it is
with the homemade heat sink installed. The heat sink is a
rectangular piece of .005" copper sheet. I think it is seven
inches long, the full length of the K&S Precision metals stock that I
bought (#15058 1piece each of brass, aluminum and copper).
I loosely folded the copper sheet in the middle and put the motor in
the fold. Now the sheet is U shaped. Then I pressed the two
legs of the U together, fully enclosing the motor. I pierced the
two legs of the U in three places to allow three zip ties to be
threaded through, but I didn't install them yet.
Next I gently bent the U open enough to remove the motor. I
smeared Ceramique heat sink compound (from a computer store) on the
case of the motor (after first removing the label from the motor), and
I carefully put the motor back into the U. I pressed the U closed and
installed the three zip ties, pulling them tight. The location of
the zip fasteners is important, since the pod is just slighly bigger
than the motor. The zip fasteners go in one of the upper two
corners of the pod (where the sides meets the top), so position the zip
ties this way before you fully tighten them. Likewise you should
position the motor how you want it. I installed mine with the two
mounting holes horizontal (left and right of the shaft).
Finally I wiped away the extra heat sink compound and shaped each of
the two legs of the U into an S shape.
