B Kinetic energy to electrical energy generator

  1. Aug 8, 2017 #1
    I am going back over the topic of electricity and energy. I am just wondering within a kinetic energy generator what is the relationship between the speed of the rotating shaft and the overall electrical output of the generator.

    That depends on the magnetic and electric circuits of the generator.

    One answer, power=torque*speed That works for gasoline engines as well as electric engines.

    Another answer, in the power grid, most generators are synchronous. Their power ranges from minimum to maximum with no change in speed.
