Generator on basis of torque

  1. Dec 28, 2012 #1
    My project produces 12 kgm torque so,I need a list of Generator which runs on 12 kgm torque and how much Current it produces... Please advise

    At what speed does your prime mover apply 12Nm?

    It rotates at 60 rpm

    So using the torque and rpm, calculate the power (and current is power divided by voltage). Then you can just google for generators that are of that capacity.

    okay so 12 kgm torque is 120 Nm and speed is 60 rpm...So using this formula P=T*pi*N/30000
    Power is .75 kw.
    Now a generator which runs on 750 watts...okay thats a little low...
    Thanks
