EXAMPLE 1
When running on full load at 400 V, a 3-phase star-connected induction motor takes an
input current of 60 A at 0.85 p.f. When running light (or no-load) at 400 V, the motor input
current and power are 16 A and 2200 watts respectively. Its friction and windage losses are
800 watts. If stator resistance per phase is 0.6 Ω, calculate the shaft power and its efficiency
at a full-load slip of 0.04
