Actual exam question for NETA's NETA_2 exam
Question #: 65
Topic #: 1
To reverse the direction of rotation of a three-phase induction motor, which action is required?

Suggested Answer: B Vote an answer

The direction of rotation of a three-phase motor is determined by thephase sequenceof the supply voltage.
Reversingany two phase conductorschanges the phase sequence, which reverses the rotating magnetic field in the stator and therefore reverses motor rotation.
NETA Level 2 technicians frequently verify motor rotation during commissioning and after maintenance.
Understanding phase rotation is essential when performing bump tests, troubleshooting incorrect rotation, or verifying wiring after motor replacement. Reversing all three phases would preserve the original phase sequence and would not change rotation.
