A) Refer to the diagram on “Speed Control of a Shunt Wound DC
Motor.
Suppose the no load voltage V = 90V, Ra +
R1 = 4 ohms, Rsh + RF = 130 ohms,
and the motor runs at a rated speed of 1000 RPM when IL
= 4 amps. What is the back EMF VB in volts when the
motor runs at IL = 6 amps?
Note: Type a 1-decimal number, rounded off to the nearest
0.1
B) How...
Gemini is looking to make a $125,000 investment in a
motor. The motor has a 5 year expected life and no terminal
disposal value. Management believes the new motor will yield
$35,000 in annual savings in cash operating costs. Gemini’s
required rate of return is 10% and their tax rate is 30%.
Determine the net present value, payback period,
discounted payback period, and internal rate of return for this
investment.
Should Gemini make this investment? Why or why
not?
Make a write up on how a stepper motor control works. The Do's
and Dont's. The motor is driven by TTL logic used to implement the
controller. Use a 555 timer circuit to operate the controller at
3Hz. Write up to be 4-5 pages.
Modify the following code to make the input and output look like
this.

Make a write up on half stepper sequence and full
stepper sequence on stepper motor control. Differentiate the two,
write a summary on findings or results. The motor is driven by TTL
logic used to implement the controller. Use 555 timer to operate
the controller at 3Hz. Write up to be 6-10 pages
Make the block diagram (Software LabView) of two control
sequence programs involving binary type signals (Digital), whole
type (analog) signals, which contain counting process. The outputs
can be light indicators. Note: The purpose of the program is to
observe in LabView how signals work. The programs can be the one
you want.
I want to make 5 sec counter from 1000Hz input frequency using D
or JK flip-flops. Anyone can help me with logic circuits and
excitation table. Also, 5-bit parallel load register with
flipflop.
