Two induction motors and one synchronous motor are fed fromthe same 3-phase, 480V bus. The following data pertains to the 3motors: Induction motor #1: 480V, 120 hp output, PF=0.78 lag,efficiency = 82% Induction motor #2: 480V, 100 hp output, PF=0.80..
As a project manager on a product development team for a new line of iPads for the hearing impaired, you are asked to create a product development plan that addressed items (a) through (f) below. The product has been broken down into the following su..
For a RLC Circuit: V=110V (rms) at 50Hz; R=5 ohms; L=50mH; C=0.1 mF; find the impedance, current, voltage across R parallel to C, peak electric energy, peak magnetic energy and stored energy.
A 6-pole, 50 Hz., 3-phase induction motor running on fullload develops a useful torque of 175 Nm when the rotor e.m.f. makes 120 complete cycles per minute . Calculate the shaft power output,If the mechanical torque lost in friction and that for c..
c. Name and briefly explain three fabrication methods for quantum wires. d. Name three potential applications for quantum wires.
The motor is operating at slip s = 0.04. Determine the input current, input power, mechanical power, and shaft torque (assuming that stray-load losses are negligible).
An LVDT Is used to measure the axial deformation a simple bar.The uncertainty in this measurement is ± 0.025mm. A steelbar is to be used to measure a force of 1100N with an uncertaintyof 1 percent.
In a multiuser CDMA system of DSSS, all transmitters are at equal distances from the receivers. The additive white Gaussian noise density Sn(f) = 5x10^-7 W/Hz. BPSK is used by all users with bit rate = 16 kb/s. There are 16 users.
A 2.0 C charge moves with a velocity of ( 2.0i + 4.0j + 6.0k ) m/s and experiences a magnetic force of ( 4.0i - 20j + 12k ). The x component of the magnetic field is equal to zero. Determine the y component of the magnetic field.
find that competition precedes cooperation.
Consider a Δ-connect, 25 kVA, 480 V, 60 Hz, six pole synchronous generator. The field current is set such that the line voltage is 504 V when supplying a rated load. Consider the armature resistance to be negligible.
If the motor is operating in a linear region, determine the torque developed by the motor
