The rated power of an asynchronous motor with a squirrel-cage rotor is PN = 7.5 kW, with a supply voltage of U1N = 220 V connected in delta, I1N = 27.54 A, power factor Cosφ1N = 0.85, frequency f = 50 Hz, pole pair number 2p = 4, nominal rotor speed at full load nr = 1440 rpm, and the induced voltage on the rotor at standstill U20 = 260 V. The nominal rotor current in star connection is I2N = 24 A. The winding temperature of the motor was measured as 75°C and the resistance between two phases was found as Ru,v1 = 0.24 ohm. a-) Find the rotor impedance Z2, R2, X2σo, power factor Cosφ2N, phase voltage U2, and frequency f2 at nominal conditions. b-) When the motor is overloaded, it draws a current of I1N = 30 A from the grid. Calculate the apparent, active, and reactive powers drawn from the grid and determine the loading ratio of the motor.

Q3. Neural Network [10 points] Consider the following neural network: $a_0$ $w_0^1$ $a_1$ $w_1^4$ $w_1^3$ $a_3$ $w_3^4$ $a_4$ $w_0^2$ $a_2$ $w_2^3$ $w_2^4$ Where $a_i = \sum_j w_j^i z_j$, $z_i = f_i(a_i)$ for $i = 1, 2, 3, 4$, $z_0 = a_0$ (an input neuron), $f_3(x) = relu(x)$, and $f_1(x) = f_2(x) = f_4(x) = sigmoid(x)$. $relu(x)$ corresponds to a rectifier linear unit transfer function defined as: $relu(x) = max \{0, x\}$. The cost function is defined as $J(w) = \frac{1}{2}(z_4 - y)^2$. (a) Write a function F to simulate the neural network. (b) Assume that we are given a training data $x = 1.0$, $y = 0.1$, what is the value of $\frac{\partial J}{\partial w_3^4}$?
