The highly efficient air-cooled motor is characterized by a superior performance structure. In addition, the drive has a large thrust bearing that can easily absorb the thrust of the propeller. The coupling is the central link in the power transmission from the motor to the propeller shaft. The system can be easily adapted to many different shaft types – metric and imperial dimensions. For optimal shaft alignment between the motor and propeller shaft, a special 3-dimensionally adjustable suspension system has been developed, which also has the necessary stability to absorb the thrust of the propeller shaft. Optimized mounting feet are included as vibration dampers. In order to transmit the maximum torque to the propeller and at the same time withstand the high thrust of the propeller shaft, the shaft must also be strong enough. The large stainless steel shaft meets our quality requirements exactly.
