3根线的电机,应该是无刷电机,转速是靠方波或者正弦波驱动,电路控制部分倒是简单(去看看4轴飞行器的论坛,上面很多这种控制器),困难的还是机械部分.
没找到MP40的拆解,找个MP10(也是只有缸外的马达部分)(英文看不懂,只有原文转发)
Old Vortech MP10 Tune-Up

After comparing the noise levels of my new 2011 Vortech with my older 2009 Vortech, there appeared to be something wrong with my 2009 motor. The older motor was revving up to the point I could hear it from the other room, whereas the newer motor was considerably quieter.
Since my older Vortech was out of warranty, I had the choice of leaving it as-is until I couldn't take it anymore, buying a new dry side motor, or fixing the problem myself. I opted to take the matter into my own hands.
Basically after disassembling the motor, the ball bearings needed to be re-lubed. I used lube you would typically find at a RC hobby store. After cleaning the motor and putting everything back together, the noise level considerably dropped. However, the 2011 motor is still quieter than the tuned-up 2009 motor, but its still better than before.
Here are some pictures of the MP10 dry side motor:

Cleaned the magnet and applied a few drops of lube on the other ball bearing.
