Motor and Motor Control Circuits Course Project 1 Quiz Answers ....Refer to our video lab on specifying a DC motor speed measurement. How does an FET work? Comment your answer below .... Refer to our video lab on specifying a DC motor speed measurement. How do you measure back EMF directly? It is not possible to measure the back EMF directly ....Refer to our video lab on specifying a DC motor speed measurement. Sup. pose the motor resistance is 2 ohms, motor inductance is 5 milli-henries, external voltage is 5 volts, and the back EMF time constant is .009 per RPM. As the motor accelerates, what is the motor current in milliamps at time t = 20 milliseconds when the motor is running at 500 RPM. Ignore any oscillation of the back EMF voltage due to commutation. Type an integer value of milli-amps. 250 ....Refer to our video lab on specifying a DC motor speed measurement. Why does the frequency of ripples in the de caying DC current signal increase as the motor speeds up? Select all that a...
Motor and Motor Control Circuits Week 3 Coursera Quiz Answers 1. What causes a motor to generate back emf? The armature windings rotate through the magnetic field created by the field windings. They then become a generator, creating a current in the opposite direction to the applied current 2. What is the power in horsepower of a DC motor operating at 1000 RPM and 2 lb-ft torque? (Type in a two-decimal number.) 0.38 3. Which of the following are causes of energy loss in a DC motor? Select all that apply. Current flow in the armature and field windings Magnetic hysteresis in the iron core Eddy current losses in the field windings 4. What is true about the speed of a shunt wound DC motor? Select all that apply. The speed is proportional to the square of the armature resistance The speed is inversely proportional to the magnetic flux 6. What is true about a permanent magnet DC motor? Items (1), (2), and (4) 7. Where might the motor control circuitry be located in a servomotor? In a separa...
