• Explain the difference between an AC induction motor and an AC synchronous motor. Include in your discussion the differences in motor construction and torque-operating characteristics. • In designing an overhead crane you need to select an AC motor for the main hoist motor. You have the choice of using either an AC induction motor or a synchronous motor. -Using Internet sources and commercial manufacturer reference material, describe what type of motor you would use for the main hoist. -Support the decision with a discussion of the advantages of the motor selected, compared to the disadvantages of the motor not selected for the main hoist motor.
Let y[n] = Odd{x[n+1]}, where Odd{f[n]} takes the odd part of f[n]. Determine if this system is a. Linear b. Time invariant c. Causal For each part, either show proof that the property holds or show an example that it does not.
A magnetic dipole mux of infinitesimal radius is located at (1, 0, 0). The magnitude of B at the origin (0, 0, 0) is 2.5 T. Find B in vector form at (3, 0, 0).
1. What does "transfer function" of a filter represent 2. What do the Amplitude Ratio (Gain) and Phase Angle represent 3. What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal F..
A 6-bit answer based on the selected Operation. The error bit is turned on if either no Operation is selected or more than one Operation is selected.
Single-phase distribution line runs parallel to a ground line and is separated by 2m. During a short circuit, the distribution line experiences a current of 10,000A rms. Determine the magnitude of the separating force acting on a 1m section of the..
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
using the schematic design entry method design a logic circuit that has two 2-bit inputs x and y a 1-bit input
Three single phase transformers are used to form a three-phase transformer bank rated 13.8kV (delta)/120kV (wye). One side of the transformer bank is connected to a 120kV transmission line
A series circuit has the following components. For each, calculate the voltage across it and the current through it. Component voltage Current 9 V source 9V 9.1 Kohm resistor 1 Kohm resistor 2.2 kohm resistor.
A. Determine the fundamental frequency w0, the period t0, and the coefficients in the representation X(t) = x0 + Re{(sigma)k=1N Xkejkwot} for the above input. C. Now consider a new signal y(t) = x(t) + 10 cos (50 pi t - pi/6). How is the spectrum ..
An object in a microwave oven 25 cm in diameter and 4 cm thick is being warmed. Determine how deeply the signal penetrates if the objects εr is 12.5 and σ is 2 S/m at a frequency of 2.5 GHz. Assume that the plane wave calculations are valid.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
