Question 199Electricity & Electronics - QMED
70% to passWhat determines the direction of rotation of an AC induction motor?
Adetermined by the number of poles being even or odd
Bdetermined as the opposite of the direction of the rotating field
Cdetermined by the direction of the staggering of the brushes
Ddetermined as the same as the direction of the rotating stator field
AI Explanation
The correct answer is D) determined as the same as the direction of the rotating stator field. The direction of rotation of an AC induction motor is determined by the direction of the rotating magnetic field in the stator. The rotating stator field induces a current in the rotor, and the interaction between the rotor current and the stator field produces a torque that causes the rotor to rotate in the same direction as the stator field. The number of poles (even or odd) and the direction of the brushes do not directly determine the direction of rotation; they affect the rotating field direction, which in turn determines the motor's direction of rotation.
