Breaking in and maitainnig a brushed motor
 |
Breaking in
Get a 3V power source. 2 alkaline D cells or a 5V line from a converted PC power supply with a 55W halogen light bulb in series will do. I let it run at this voltage for 36 - 48 hours. This gives a perfect contact surface area between the brushes and the com. I also put a cooling fan and heatsink on the motor at this point.. I did it with my sport motor and that thing never got hotter than 120 F! Clean it thoroughlmy after it's run in |
Cleaning
I cleaned it out every 5 or 6 flights by flushing it with the motor cleaner until it ran "clear" from the bottom of the motor. Then I'd just put a small drop of oil on each bearing and be ready for the next 5 flights or so. Spray brake cleaning fluid from your auto parts store can be used for cleaning too. The cheapest brand will do. I also never cleaned it hot.. always let it cool to ambient temperature before hitting it with the motor cleaner. Learned this lesson the hard way after warping the com on my first Magnetic Mayhem Reverse. I also throw out the stock brushes and install hard compound (P compound) brushes. They hold up to the current demands of the ECO much better. |
