Rotax 912 IS 发动机带有发电机A和B,功率为：220W和420W

The internal generator has two isolated coils integrated (individual generators).During the starting operation, the EMS system is powered by the

battery. With sufficient speed generator B takes over this function. After the EMS system check, generator A takes over the supply of the EMS

system (engine), if the switching threshold is exceeded. Generator B is then used to supply the aircraft instruments and for charging the battery.

While the engine is running, generator B can be used for the board instrumentation.

- Generator A 14.2 V/16 A (220 W nominal capacity at 20°C/68 °F)

- Generator B 14.2 V/30 A (420 W nominal capacity at 20°C/68 °F)

对于需要用到大功率设备，Rotax也为客户提供额外发电机。其功率为550W。
