- If you observe in your experiment that the peak efficiency of your motor occurs at ω=5.2 and T=0.054 and you need to lift a mass of 218 g, what is the pulley radius (m) that should be used to achieve peak efficiency?arrow_forwardYou are Working as a plant electrician. You were told that a large DC motor was returned from the rewind shop and was installed on the previous shift. The motor seem to operate properly until the load was added. The motor then stopped, reversed direction, and begun to run at high speed. What is the probable cause of the trouble, and what would you do to correct the problem? Explain your answer.arrow_forwardQ3:A: (a) A 10-hp 230-volt shunt-wound motor has rated speed of 1000 rpm and full-load efficiency of 86 percent. Armature-circuit resistance, 0.26 ohm; field-circuit resistance, 225-ohms. If this motor is operating under rated load and the field flux is very quickly reduced to 50 percent of its normal value, what will be the effect upon back emf, armature current and torque? What effect will this change have upon the operation of the motor, and what will be its speed when stable operating conditions have been regained?arrow_forward
