Problem 8 ( please answer neatly )
a) Draw the dc-motor equivalent circuit and its representation
in Laplace domain. Is
this representation linear?
b) What is the transfer function of a proportional-integral (PI)
controller?
c) Draw the block diagram of the torque loop.
1-Select one of the DC motor type belonging to any company and
specify the motor parameters from its catalog/datasheet.
2-Calculate the maximum inertia value of the load to be driven
according to the motor inertia specified from catalog, use given
rule below to specify gear ratio plugged between load and DC motor
If your student id is 12568013, then
u=(1+2+5+6+8+0+1+3)/5
u = = 5.2
3-The speed measured from the rotor of an asynchronous motor
with 12-pole,
80 Hz is K...
I have a question for the effect and difference on a DC motor
for the speed( rad/s) in time (sec) if you apply:
1. Nothing (so no charge in the circuit only the mecanic charge
of the generator)
2. A resistant charge (only the resistant is plug in with the
generator)
3. Short circuit (No exterior electric charge but the terminals
are bounds together so an excessive amount of current flow into the
circuit)
4. Capacitive charge (only the capacitor...
You are to compare and contrast a DC and an AC motor.
Make a table with 2 columns: one for DC and one for AC and explain
each of the following
1; What are their parts and what are their functions
2. How do they work (the physics behind it)
3. What are they used for, give some examples
4. Make sure to include schematics, drawings, graphs
(a)
In DC motor, quadrant of operation can be defined by the
armature voltage and
current of the motor. By using an appropriate diagram, briefly
explain the
definition of all four quadrant of operation based on armature
voltage and current.
(b)
A chopper is used to control speed of 45.36 kW, 1750 rpm, 240 V,
189 A
permanent magnet DC motor with 0.01 Ω armature resistance. This
chopper-fed
DC motor is able to operate in both motoring and braking
mode...
Design and analyse of a circuit which turns a DC motor at a
speed which is proportional to how much a temperature is away from
a set temperature, and turns:
Clockwise when temperature is greater than (say) 25 degrees
C.
Anticlockwise when the temperature is less than (say) 20 degrees
C.
Such a circuit might be used to regulate the temperature of a
room by turning a ceiling fan to move warm air in/out of that room
(using the roof...
