- A 230 V 20 Hp 60hz Six Pole Induction Motor Is Driving A Constant Torque Load At Rated Frequency Rated Voltage And 1 (13.58 KiB) Viewed 74 times
A 230 V, 20 hp, 60Hz, six-pole, induction motor is driving a constant torque load at rated frequency, rated voltage and rated power has a speed of 1175 rpm and an efficiency of 92.1%. Determine: (1) The new operating speed if a system disturbance causes a 10% drop in voltage and 6% drop in frequency (ii) The new shaft horsepower, assuming all loses (windage, friction and stray power) are constant
