    I am trying to determine the parameters of various induction machines.
    I am wondering if there are any measurment tests (such as with a meter clamp) I can do to determine HP, KV, FLA, and LRA?

    Dear friend LW, why do you have to be so rude!? people join this forum to educate themselves and upgrade their knowledge. If all would be experts then everyone would be Einstein!

    I am trying from my point of view to help,asking question is ok.
    you should help If you want. What I'm trying to say you can read
    a chapter is a book,It would help If you had a picture in your mind
    what Is happening associated with real life experience like car radio
    and c.d. player. Remember to keep your respect. You notice a lot
    motor tech's did not jump on this post,there are strange ways to
    determine h.p. like useing buckets of sand and pulleys as a way
    to determine h.p. load .

    You will not know your motors voltage rating, unless it's either stamped on the ID tag, or you have that info from the winder/manufacturer. Code requires an ID tag.

    HP is similar. If you knew the voltage, %speed regulation, and power factor, you could do a lines measurement / calculation to come up with a close hp.

    FLA and LRA can be done with an ammeter. LRA can be around 600% FLA.
