Synchronous motor-exercise

  1. Jan 28, 2017 #1
    Hey there world, I have a question about a specific exercise, which involves a synchronous motor.

    A synchronous motor, 260V, 50Hz, in delta connection ( Δ ), has induction resistance 2.5Ω, whereas ohmic resistance approximately 0. If the losses of friction and windage are 1500W and the core losses are 1000W, compute the current per phase, when the motor serves a load 15Hp.

    I get stuck in this problem. I believe I need an extra data to solve it. Also, I don't remember if the professor told us to take a specific data as known, even though it is not shown anywhere in the problem. Anyway, this is so far what I got ---->
