Problem 4 [20 points]: Figures below are related to a 208, 45hp, A-connected, 60Hz, 2-pole synchronous motor: Syne Motor 61 H +Ex R. X₂ RA V₁ = V₁ Assume: • The core losses are 1.0kw and friction/windage losses are 1.5kw • The rotor copper losses are 2.0kW and the losses in field winding are ignored • The load on the shaft is 40hp and the power factor of the machine is 0.8 (Lag) (a) - Find the reactive power absorbed by the machine. (b)- Find the induced torque in the machine. Solution:
