BRP Rotax has introduced Generator Flange Part No. 953978. SI-PAC-023 explains drive flange integration and maximum torque i.e, 116 Nm at takeoff rpm. However, I think that SI-PAC-023 does not fulfill all the requirements for proper integration of optional accessories with drive flange.
For example, Can I install belt driven external generator/alternator of 500W. If yes, then I have to install driver pulley on the generator flange. If I install driver pulley on generator flange, then there will be bending load on generator flange due to belt tension. So, there must be some limit of maximum driver pulley length and allowable bending load on generator flange which rotax has not provided in the SI-PAC-023 or any other document.
SI-PAC-023 is attached.
