A 300 kW, 6600 V, 8-pole, 50 Hz, three-phase, Y-connected, non-salient pole (i.e., cylindrical rotor) synchronous motor has the following parameters:Xs = 72 ohm /phase at 50 Hz, R =10 ohm/phase for operation near base speed, and Efo = 3200 V/phase at base speed.(i) What is the base speed of the motor in mechanical rad/sec and rev/min?(ii) Calculate the load angle ( of the motor when it delivers rated load at base speed.(iii) Calculate the motor input current (I) and power factor (PF) of the drive for this condition of operation.(iv) Calculate the maximum power and torque the motor is capable of developing while running at base speed.
Let x1[n] = {-2,1,-3,-5,6,8} with arrow under -2 and x2[n]={1,2,3,4} with arrow under 1. a) determine circular convolution of 7 between x1[n] and x2[n] b) verify (a) calculations by computing the DFTs and IDFT.
the bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12k
Finding the periodicity in N of the discrete time signal x(n) = Cos(3pi*Ts.n + pi/4) and then plotting the discrete signal. From this the condition on the sampling period is determined
There are three numbers stored in Memory Locations 10-12. Write a machine language program to load each number in the accumulator one at a time. Use the immediate addressing mode to add four to each value that is loaded to accumulator.
Dynamic RAM that must be given a refresh cycle 64 times per ms. Each refresh operation requires 150 ns. memory cycle requires 250 ns.
Identify the steps involved in the delivery of a letter from the sender to the addressee. How are these steps similar to OSI layers' functions such as addressing, routing, resource sharing, error checking, and connectionless vs. connection-oriente..
