    Hi All,

    I am working on a pump equipment and it is using a 3 phase AC motor that runs in 120Hz and voltage rating of upto 350Vac. I want to make a set-up that will only check the motor and pump and to do that I need a driver that is capable of delivering up to 400Vac and load of 2A. Does anyone know such kind of driver? I did searched in google but all I found are 220Vac to 250Vac. I dont want to spend so much time of building one as I really need it so urgent and don't have much time to build.

    Thanks,
    NH

    A lot more information is required on the motor to give any kind of informed answer, if it is a 3 ph motor and runs on a fixed 120hz then this requires some kind of specialized driver.
    Is it P.M. field or induction or wound field?

    Wouldn't a standard VFD work for you?

    Correction it is a 1phase wound field motor. The motor specs 120cycle .056HP 250V. VFD would work but what I need is the following specs:

    1. output form 0-400Vac/120hz or 0-350Vac/120Hz
    2. 1 phase

    What about this? 3 phase?:confused:

    Which is why I suggested a VFD.

    More info needed on the motor technology as apparently it is not a normal induction motor if it has a wound field?
