DC Bus Generator

DC Bus Generator



GreenMachine is a highly efficient permanent magnet electrical machine for propulsion and electric power generation. Low speed versions of GreenMachine are available for direct mounting to a propeller shaft without gearboxes. Medium and high speed versions
are available for connecting to third party thrusters and gearboxes (parallel hybrid). GreenPower consists of a variable speed combustion engine connected to a GreenMachine acting as electric generator. In this way a highly efficient and light weight electric power generator plant is realized to further support a green environment.


GreenMachine and GreenPower

GreenMachine is a highly efficient permanent magnet electrical macine for propulsion and electric power generation.  GreenMachine is available in RPM ranges in between 266  (low speed direct drive of propeller shaft) and 3600 (high speed generator set). GreenMachine can be either flange or bracket mounted. In addition, customer can choose between hollow shaft or solid shaft on one side or on both sides of the machine.  In case of parallel hybrid applications, the low speed GreenMachine can be connected to the propeller shaft on one side and the other side can be connected to the output shaft of gearbox.

GreenPower is built-up with a light weight and high speed diesel engine connected directly to a highly efficient GreenMachine electric generator. In this way a very compact and efficient generator set is realized. GreenPower can be built-up with diesel engines from Hyundai, Volvo, Steyr and Cummins. Flange mounting connections, vibration damping plates and other specifications can easily be adapted to accommodate other combustion engines.

GreenMachine and GreenPower are cooled by water cooling (50% water/50% glycol). Each GreenMachine and GreenPower is controlled by a GreenInverter which is connected to DC Bus of nominal 832VDC.
