Lehner 4140 Outrunner
It takes time to invent new and innovative concepts - but we have made it.

  •  For our new outrunner brushless motor we use pressed wire coils improving the known techniques:
  •  Each single coil has a fill level of more than 70% (usually the fill level is 50%).
  •  Adhesion of the new coils with the stator improves the thermal conductivity.Additionally the design of the front and rear plate assure   
  •  Optimized  air flow that keeps the system cool.
  •  The new coils increase the power density. Our new motor with an 83 mm outside diameterwill have the same output power as contemporary  motors with a 100 mm outside diameter.This has advantages for airplanes with small cowls.
  •   A 12 layer HiAmp circuit board allows parallel connection of all coils. This allows a highgranularity of revolutions per minute by changing the number of wires per coil (please refer to rpm list).
