design a stepper motor in 8051 microcontroller in
which stepper motor moves clockwise for some time and stops , then
anticlockwise for some times and motor stops. (Code in assembly
language needed)
A robotic arm is controlled by several stepper motors.
Stepper motor (or step motor)
is a brushless DC electric motor that divides a full rotation (360
degree) into a number of equal steps (10 degree/step in this case).
The motor's position can then be commanded to move and hold at one
of these steps without any feedback sensor (an open-loop
controller). This motor usually has 4 wires. To move a motor, the
following bit patterns should be applied to these...
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
Give some examples of how the interests of different stakeholder
groups may be in conflict. What is the agency problem? What steps
can be taken to solve it? Discuss this topic in terms of how it
relates to your own organization, or a company with which you are
familiar.
Strategic Resource Allocation and Planning - is the name of this
class
Give two examples or cases, where you (as a future engineer) may be
under pressure by the manager or boss to do an action that is
basically violates the “Code
of
Conduct” or “Engineering Ethics.” This action that are asked to do
may hurt you, the company or the customers and
consumers.
a. Give some examples where a bank would use securitized
instruments.
b. Describe an example where a bank could control their risk
exposure to a counterparty or asset class using Securitized
instruments such as CDS or MBS.
c. Why would a counterparty purchase these securities offered by
the bank?
1. Please describe and give examples of some claims that may be
settled with something other than cash
2. Define and explain what you understand by the depreciation
expense and accumulated depreciation. On which statement are they
reflected?
1a. Give 6 examples where Energy is Conserved in an event.
1b. Give 6 examples where Energy is NOT Conserved in an
event.
1c. Give 2 examples of an event where Momentum is NOT
Conserved.
The terminal voltage across a single phase of a stepper motor
used as a generator is applied across a load resistor of 33 ohms.
This terminal voltage has an amplitude of 18.7V and a frequency of
242 Hz. From a previous measurement, we know that this stepper
motor phase has an internal resistance of 11.2 ohms. What is the
time-averaged power delivered to the load? What is the electrical
efficiency of this circuit? Write down an expression for the
instantaneous...
