Question
Chapter 31, Problem 1RQ
To determine
Identify the number of slip rings on a rotor shaft of wound rotor motor.
Expert Solution & Answer
Explanation of Solution
One of the three major types of the three-phase motor is the wound rotor motor. The wound rotor motor is the first AC motor with speed control.
The wound rotor motors are also known as slip ring motors and have three slip rings on the rotor shaft.
Hence, there are three slip rings on a rotor shaft of a wound rotor motor.

We will consider a linear system and a nonlinear system under uncertainty, each expressed in the form
of a set of stochastic differential equation (SDE) as follows:
=
da (Ax+ Bu)dt + Gdw,
dx = f(x,u,t)dt+Gdw,
(1)
(2)
where x is the state, u is the control, and dw is a differential increment of standard Brownian motion, i.e.,
E[dw] = 0 and E [dw(t)dw(t)] = dt-1.
In this problem, we consider the linear SDE, Eq. (1), with a very simple model where x = R², u = [0,0]
(no control), and dw R². The matrices A, B, and G are given as follows:
A=02x2, B=02x2; G = [000]

where σp Є R represents the degree of the uncertainty, and let us take σ₁ = 2 and σ2 = 3. Assume that the

The other end of the rod is attached by a string of length I to a fixed point which is located a distance 21 from the wall. A horizontal force of magnitude F, is applied to the lower end of the rod as shown. Assuming the rod and the string remain in the same vertical plane perpendicular to the wall, find the angle 9 between the rod and the wall at the position of static equilibrium.

- Problem: You and your team are tasked with designing an around-coil system for an air-conditioning unit that will be installed in a hospital. The system must provide a controlled environment for the hospital's air-conditioning needs, ensuring that fresh air is brought in while exhaust air is expelled, without allowing contamination between the two airflow directions. The air-conditioning system will include two coils and two pumps (one duty pump and one standby pump) in a configuration that accommodates both exhaust and supply airflows. The system needs to comply with ASHRAE Standards, and ASME BPVC Section VIII, with attention to safety, reliability, and efficiency. The system will be used in a climate with moderate temperature variations, and its design will need to consider a range of operating and design specifications.

- compute the work done by a fuel-water interaction assuming that the 40,000 kg of mixed oxide fuel and 4000 kg of water expand independently and isentropically to 1 atmosphere. Assume that the initial fuel and water conditions are such that equilibrium mixture temperature achieved is 1945 K. Other water conditions are as follows: Tinitial = 400K, ro initial = 945 kg/m^3, cv = 4184 J/kg-K.
