The idea of pulling the air rather than pushing it comes from the fact that you already have a poorly operating pusher fan in the motor housing... it's not doing much, but helping to direct airflow... Add a puller to that on the other end, and you could possibly have the key to keeping your heat down, and keeping the motor evenly temperate... I'm assuming this is a good thing for E-motors.

Shouldn't be too hard to make a cone that fits your motor on one end, and a small round fan slightly larger than your motor on the other... place the fan so it's pulling air through the motor, find a way to fasten it, then wire it up with a thermoswitch, so it only works when the motor gets over, say, 120*F.

I'm not sure what the optimal temp for your motor is, so bare with me on that.
