An electric vehicle has its wheels driven directly using a 3 phase ,Y connected, 340 V (line to line ),4 pole induction motor powered from a battery bank through a motor speed controller at 50 Hz .The single phase for equivalent circuit parameters for the windings of the motor referred to the stator in (ohms/phase) R1=0.2 R2=0.2 X1=0.3 X2=0.3 .the core losses and the magnetization can be ignored.The total friction and windage losses may be assumed to be constant at 600 W.For a slip of 8%, calculatethe stator current ,power factor,real power and apparent powerthe rotor real power lossesthe mechanical power output and efficiencythe rotor speed and developed torque
1. Derive boundary conditions for electric fields (both for tangential and normal components) 2. Derive boundary conditions for magnetic fields (both for tangential and normal components) 3. Why boundary conditions are so important in electromagnetic..
Let x[k] be a time-domain sequence and X[r] be its DFT. (When written as vectors, unless stated otherwise, always assume the first entry in the vector is at k=0 or r=0, respectively.) If x[k] = [5, 9, 6, 10]
1. Use the Quine-McCluskey minimization method to find a minimum cost SOP realization of the following functions (a) f(x1,x2,x3,x4)= fm(0,2,4,5,7,8,9,15) (b) f(x1,x2,x3,x4)= fm(0,4,6,8,9,15) + d(3,7,11,13)
Consider an InGaAs APD with excess noise x=0.7, M=10 where M is the multiplication factor. The unmultiplied dark current is 10 nA and bandwidth is 700 MHz. What is the avalanche photodiode noise current per square root of bandwidth
Discuss the sequence of actions that occur in the operation of the control system for a traffic light that includes sensors in the roadbed. Indicate which actions are time-driven and which actions are event-driven.
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
A toroid is fille with liquid oxygen that has a magnetic susceptibility of 4*10^-3. The toroid has 2000 turns and carries a current of 15 A. Its mean radius is 20 cm, and the radius of its cross section is 8 mm. (a) What is the magnetization
Someone needs to explain to me how in God's name can you get a value of 600 watts from 2 sources, one of value 400 watts and another of -600 watts
Include worked solution, a discussion of any differences in the theoretical and measured values and screenshots that show your measurements and paste them into a document
The s-plane diagram of a filter shows that it has a cluster of four poles in the left-half s-plane that are arranged in a semi-circle near +/- j628. The filter also has two zeroes at the origin.
Write an instruction sequence to subtract the 6-byte number stored at $800-$805 from the 6-byte store a $810-$805, and save the result at $900-$905
I)Design a circuit that gives you the following relation between input and output Vout = 2.17Vin + 5 Here are the constraints you need to work with: 1) Only one power supply that gives ±12V is available 2) Available op-amps run on ±12V
