Question - Explain why the following motors are used in the particular applications indicated against them. Synchronous motors - power-factor improvement, DC shunt motors - lathes, DC series motors- lifts and cranes, Cumulative compound motor - rolling mills.
An integrated circuit employs the source follower and the common-source stage shown in Fig. 9.37(a). Design a current mirror that produces I1 and I2 from a 0.3-mA reference.
Calculate the voltage drops across R1 and across R2. Measure total current for the circuit and compare it to your calculated value in step 1. Be sure to provide a screenshot displaying the measured result.
Design a proportional-integral controller so that phase margin of the loop transfer function and the crossover frequency is no larger than 10kHz. Provide the close loop bode plot
A three-phase, 2300-V, 60-Hz, cylindrical-rotor synchronous motor has a synchronous reactance of 10 ohms per phase and negligible armature resistance. The motor delivers 250 hp at a power angle of 20 electrical degrees, and the efficiency is 90%
Problem 1: (a) Give three examples of each of natural (free) convection and forced convection which occur in industrial processes.
A certain practical dc voltage source can provide a current of 5.5A when it is (momentarily) short-circuited, and can provide 28W to a 20Ω load. Find a.)The open-circuit voltage b.)The maximum power is could deliver to a well chosen RL
It dispenses water and beer. Use 3 of the logic switches to simulate the coin detectors (one each for nickels, dimes and quarters) and use two of the indicator lights to simulate the dispenser valves for water and beer.
Taking an example from Turkey, explain the quantitative differences between energy and exergy utilization from primary sources
Briefly discuss (1 paragraph) the impact/ trade offs of the various components in the circuit - Design a feedback transfer function
Each city has a starting population and annual growth rate. The smaller city has the larger growth rate (required). Show the comparative populations of each city year by year until the smaller city has grown larger than the bigger city.
If the change in voltage is assumed to be linear between no-load and full-load kilowatts, calculate the kilo watt output of the generator when the terminal voltages are 240V and 235V.
Develop the ow-graph for the FFT algorithm from the radix-2 FFT algorithm for the N = 9 case in which the input is in the bit-reversed order and the output is in normal order.
