Help on generator for engine tuning

  1. Feb 7, 2012 #1
    We have a single cylinder 500 cc petrol bike engine. It's maximum power output is 27bhp( max) and the max rpm of the engine is 5000 rpm. We need to tune the engine to MAP it accordingly. We are thinking to use a generator to convert the mechanical power into electrical power.

    I need help on the generator :
    The generator available in the market are as
    Output voltage: 230 v single phase
    Power : 2kw ( I need help on this parameter)
    Max rpm : 1500 to 3000(very rare)

    My doubts are:
    1) The power rating given is mechanical or electrical. Also is it the maximum or the minimum power.

    2) Also we are using the 1500rpm generator, to get the 5000rpm equivalent we are using a 3:1 or 4:1 gear arrangement. So if My engine gives some output which is above the rated rpm of the generator then will the generator get damaged? IF yes then suggest the proper one. IF no then at what power the motor will stop running??

    Please help, I need it for my collegiate project.
