Lehner Outrunner

Lehner 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).

Note on custom-made products based on customer specifications:
Custom-made products from our company on customer's request are excluded from exchange, because they are individually manufactured according to the technical specifications of our customers and thus comply with the exceptional conditions of the right of withdrawal §312g paragraph 1. Please have understanding for this.
