Misidentifying terminals can lead to short circuits or failure to start. The sequence in which these phases are energized dictates the direction in which the magnetic field rotates.
Verifying Phase Sequence to Ensure Correct Motor Rotation
Understanding Three-Phase Motor Rotation The rotation of a three-phase motor is determined by the rotating magnetic field produced within its stator. Typically, three line wires—representing the three phases—are connected to the respective terminals.
Practical Implementation and Wiring To execute the change, the power supply to the motor must be safely disconnected and verified as de-energized. Role of Phase Sequence Phase sequence refers to the specific order in which the voltage waveforms of the three phases reach their peak values, typically labeled as L1, L2, and L3.
Verifying Phase Sequence to Ensure Correct Motor Rotation
If the rotation is incorrect, the power must be cut again, and the wires re-evaluated to ensure the correct pairs were swapped. In a standard forward rotation, the sequence might be L1 → L2 → L3.
