Wind motor determining Amperage

Discussion in 'Start here' started by raul, Jul 10, 2019.

  1. Hi, I am working on a project where I want to reduce as much load as I can. So my idea is to figure out between what RPMs I need to run the motor to get my desired voltage. (To avoid using a charge controller and I am using it as a generator)

    However, I am missing key information which is figuring out the amperage? Is there a way to get a rough estimate of amperage running at a certain rpm?

    I have a motor rated as: 120v , 3500 rpm, 50w
    I want to run between 262.5rpm & 182.29rpm
    which will produce
    • run at 262.5 rpm produces accounting for inefficiency ~7.2V

    • run at 182.29 rpm produces accounting for inefficiency ~5V
