Draw the control circuit of a motor starter system that controls two motors A and B. Each motor must have its own start and stop push button. Each start push button must have a memory or latch function so that the motor stays running when the button is released. each motor must have a green pilot light which is on when the appropriate motor is running. the circuit must include a red pilot which should be on when no motor...

Prelab 1. In your lab notebook draw the schematic diagram for a three-phase wye-connected induction motor with its three-phase stator winding connected to the three-phase power supply through 25-Ω resistors. Connect two er analyzers in the circuit (between the 25-Ω resistors and the motor) to read the total power absorbed by the induction motor. What is the function of the resistors inserted in the circuit? 2. After reading this lab handout, draw the circuit diagram for the induction motor-synchronous generator...

A three-phase induction motor delivers 500 hp at an efficiency of 0.91, the operating power factor being 0.76 lagging. A loaded synchronous motor with a power consumption of 100 kW is connected in parallel with the induction motor. Calculate the necessary kVA and the operating power factor of the synchronous motor if the overall power factor is to be unity. Answer should be 365 kVA, 0.274

Q6 A 50 hp 440 V three phase induction motor is used to determine the power rating of a load. With the load connected to the motor shaft, the input power is 30.5 KW and the stator current is 34.5 A at rated voltage. The blocked rotor test on the motor yields a current of 44.3 A at 52.5 V and a power input of 2.1 kW. When running with no load at rated voltage, the motor takes 16.3 A...
