Extracted text: QUESTION 1 a) Write down three (3) factors that will determine the induced torque in a DC machine. b) Explain why higher voltage applied to a motor doesn't always mean that it will have a higher induced torque. You can give an example of the scenario to answer this question. c) When a motor is powered up and rotates, it will induce an internal generated voltage. Is this statement true or false? Justify your answer. d) For the core design shown in Fig. 1: i. Design the magnetic circuit model. Indicate clearly for each part that you use in the magnetic circuit which part of the core is represented. ii. Predict what will happen to the total reluctance if the depth is increased.
