Torque [ft-lbs] RPM Power Output [Hp] Voltage [V] Current [A] Apparent Power [VA] Wattmete r True Power [W] Efficiency [%] Power Factor [%] Plots: Include title and label all axis with units! Questions: Answer any specific questions 1. Calculate the capacitor required to bring the power factor to 0.90 with 0.75 ft lbs torque on the motor . (Show these calculations on a separate sheet.) Discussion Discuss how the efficiency, power factor and speed are affected by the applied load. Which method of power factor correction is more effective? At what load is the motor operating most efficiently? What are the consequences S F Kelly 2 CalPoly BRAE...
