A 3-phase 50Hz 2-pole 440V (L-L rms) induction motor drive has a rated speed of 2955 rpm and rated torque of 35 Nm. This motor drives a load with a torque characteristic that increases linearly with speed such that it equals the load torque at the rated speed. It draws a current of 3.0 A(rms) per phase at the rated voltage at a power factor of 0.81 (lagging). The stator resistance Rs = {r_s} ohms. At the rated operating speed,...

3. In a sample of 125 electric motors, the average efficiency (in percent) was 88 and the standard deviation was 2. Construct a 95% confidence interval on the mean μ. Construct a 99% confidence interval on the mean μ. This interval has higher confidence: how did the interval change as a result? If the interval is (87.50, 88.50), what is the level of confidence? How many motors would have to be sampled so that the 95% confidence interval specifies the...

A three-phase, 60-Hz, 4-pole, 440-V (line-line, rms) induction-motor drive has a full-load (rated) speed of 1746 rpm. The rated torque is 40 Nm. Keeping the air gap flux-density peak constant at its rated value. The frequency and voltage of the motor from above are adjusted such that the fan speed is changed to 600 rpm. The motor should be operating at 3% slip and rated Bm. What is the motor efficiency?
