For an armature-control DC motor the following parameters are given: ea=22V, f=5x10^-3 onz-in/rad/sec, J=4.27X10^-4 in-onz-sec^2, La=0, Ts=10 onz-in (stall torque), wo= 480 rad/sec (no load speed), K=7.66 in-onz/amp. Define K= TsRa/ea, Kb= ea/wo, find the closed-loop transfer function of
(H)(s)/Ea(s),
draw the schematic diagram of the DC motor.
A system is described by the differential equation ty'(t)-8y(t)=x(t). Classify the system as to linearity, time-invariance and stability. A system is described by the equation y(t)= \(\int_{t/3}^{-\infty}\)x( \(\lambda\)) d.
Determine experimentally the value of a resistor that when placed across the battery will make a measurable change in measured battery voltage. Keep the voltage decrease from open circuit value to 10% or less.
A positive sequence three phase source has Van(t)= 200cos(wt+120) V. Find time domain expressions for vbn(t), Vcn(t), Vab(t), Vbc(t), and Vca(t).
A 60 hp, 3-phase motor absorbs 50 kW from a 600 V, 3-phase line. If the line current is 60 A, calculate the following: (a) The efficiency of the motor (b) The apparent power absorbed by the motor (c) The reactive power absorbed by the motor
In the "far field" region, show that the electric field intensity of a linear electric quadrupole decays much faster in space than 1/R3 for the electric field intensity produced by an electric dipole and 1/R2 for an electric monopole.
An electric flux of 151 Nm2/C passes through a flat horizontal surface that has an area of 0.715 m2. The flux is due to a uniform electric field. What is the magnitude of the electric field if the field points 10.3° above the horizontal
write a program that calculates the quadratic equation. the program should be able to compute imaginary numbers (i.e. sqrt(-1)). finally, output the tow result. hint: the computer cannot directly compute imaginary numbers
the N-type P-type doping levels of a silicon p-n junction are nd=na= 5x10^16 cm^-3 caltulate the built in voltage Vbi a) at a room temperture b) at 300c c) at 700 c (ni= 1.10x1018 cm^-3) does a negative value for Vbi mean anything
Teh energy stored in a 2H inductor os 130 J and is increasing at 200 J/s at t=4s. A) Determine the current magnitude at t=4s. B) Determine the voltage magnitude at t=4s.
What is the function of the enable control input of a tri-state buffer If the output of two or more tri-state buffers is connected to each other, what is the restriction on enable control input lines What does happen when this restriction is viola..
Using D-type flip-flops, design a synchronous Moore finite-state machine that monitors two inputs A and B, and asserts a scalar output if the number of 1s observed on the inputs is a multiple of 4.
Suddenly there is a short-circuit on the electric grid, and the electrical output goes to zero for 2 seconds. Calculate the increase in speed in rpm during this interval. Assume that the shaft-torque remains constant
