A four-pole 60-Hz 240-V-rms induction motor operates at 1750 rpm and produces 2 hp of output power. The load is a hoist that requires constant torque versus speed. Assume that the motor is operating in the range for which torque is proportional to slip and write an equation for motor torque in terms of slip when operating at rated voltage. Then modify the equation for operation from a 220-V-rms source. Estimate the speed when operating the hoist from a 220-Vrms source.
