Question 311Electricity & Electronics - QMED
70% to passHow is the reversal of an AC, three-phase, induction motor accomplished?
Ainterchanging any two of the three line leads
Binterchanging any two brushes
Creversing the position of the slip rings
Dchanging all three motor leads
AI Explanation
The correct answer is A) interchanging any two of the three line leads. To reverse the rotation of an AC, three-phase, induction motor, you simply need to interchange any two of the three line leads. This will reverse the direction of the rotating magnetic field in the motor, causing it to spin in the opposite direction. The other options are incorrect because they do not properly describe how to reverse the rotation of a three-phase induction motor. Changing the brushes or slip rings would not affect the rotation, and changing all three motor leads would not necessarily reverse the direction.
