Searching for a suitable electric motor that would fulfil all our technical requirements was one of the first challenges when we were developing the FES System. After evaluating available electric motors on the market, it was quite logical and easy to decide: We need to design our own electric motor.
Bench testing of our first prototype was encouraging. After a few more prototypes, and numerous improvements, the end result become FES M100 motor as we know it today.
FES M100 Motor is an out-runner BLDC brushless synchronous permanent magnet motor with electronically controlled commutation system 3 phase. Because of the very little internal resistance of the motor, good performances are achieved in a wide range of power with excellent efficiency.
Shape of front torsional plate is adjusted according inner spinner surface of each specific FES sailplane type. Otherwise there are just minor differences between different FES motor types.
