Yuneec 81 hp (60 kW) Direct Drive Brushless DC Motor (and Some Testing)

With low rpm (2400 1/min) this is an interesting direct propeller drive motor for the next generation fully electric aircraft. On top of all you get the whole power pack from the same company, including motors, controllers, chargers and batteries.

Here is an interesting video about a kit been tested in an old VW.

and an other controller driving 3-phase AC motor from DC.

in an airplane application you might not want to have any shutdown circuits even if the drive might be getting hot .. you just slow down so much that the circuit cools down and give a warning light.
