Reference no: EM131315337

There is a three-phase IG of 110 V, 60 Hz, 4 poles, 1900 rpm, Y stator connection, and an equivalent circuit given as R₁= 0.20 Ω, R₂ = 0.42 Ω, X₁ = 0.15 Ω, and X₂ = 0.43 Ω; R₂ and X₂ refer to the stator.

The excitation current is 8.1 A and is assumed constant at the rated values. Due to a reduced flux density, the excitation current is neglected at starting conditions. Evaluate

a. The maximum torque in N m.

b. The slip factor at the maximum torque.

c. The torque to generate the rated voltage.

d. Full-load torque.
