Consider a three-phase machine with the following, Ask an Expert

Engineering

Consider a three-phase machine with the following parameters: rs = 72.5 m Ω

The load torque varies with the speed cubed, and is such that 50-hp is required to spin the load at 1800 rpm. A balanced three-phase voltage source with a 460-V line-to-line rms amplitude and 60-Hz frequency is applied to the machine. Taking the a-phase voltage to be the zero reference for phase, find the rotor speed, the phasor representation of the a-phase current, the input power, the output power, and the efficiency.
