I don't spend as much time as I'd like on this forum, but someone pointed this thread out to us.
Sailmonkey is correct. The petrol/gas version of our pressure unit uses a Honda GXH50 (50cc) motor in it, but it is not a generator. There is a belt drive off the shaft to directly power the lift
pump and the high pressure pump. The system was certainly inspired
by the Honda EU2000
though, and Honda have been very supportive in our design.
This is part of the reason it is so miserly on fuel. A generator and an electric pressure system has to convert mechanical energy into electrical
, transfer it to the electric motor
, which converts electrical
energy back to mechanical. There are losses at each conversion stage. The 50cc motor we use is the same one Honda puts in their 1kva generator. The Honda 1kva generator is not powerful enough to drive our electric unit because of those slight energy losses described above.
Many people also ask whether we can add a generator capability on the petrol/gas unit as well. We designed the system to incorporate the smallest motor we could while sufficiently meeting our pressure and flow rate parameters. As such, there is simply not enough spare energy to use it as a generator as well.
Our electric unit followed the similar single
power plant design principles, but with a fully sealed induction motor. We designed it with a through shaft, so we can put the lift
pump on one side and the high pressure pump on the other. Thus there is only one electric motor
in the system that runs at just under 1300 watts, perfect for a Honda 2kva generator.
