Question 207Electricity/Electronics - QMED70% to pass
What type of motor is illustrated by the schematic of figure "B" of the illustration and what type of starting relay is used? Illustration EL-0209
AI Explanation
The correct answer is D) capacitor start, induction run motor using a potential starting relay.
This is correct because the schematic in figure "B" of illustration EL-0209 depicts a capacitor start, induction run motor configuration. The capacitor in the starting winding circuit provides the necessary phase shift to get the motor started, and a potential starting relay is used to engage the starting winding.
The other options are incorrect because they do not match the motor configuration shown in the illustration. Options A, B, and C describe split-phase induction motors, which have a different starting winding arrangement than a capacitor start motor.
