In a standard forward rotation, the sequence might be L1 → L2 → L3. Practical Implementation and Wiring To execute the change, the power supply to the motor must be safely disconnected and verified as de-energized.
Step-by-Step Reverse Three Phase Motor Rotation Wiring
This simple swap of any two lines is the physical mechanism behind changing the motor's direction. For technicians and engineers, mastering this process is critical for troubleshooting, installation, and ensuring machinery operates as intended.
To reverse the rotation, a qualified electrician will swap the positions of any two of these wires. This procedure involves altering the sequence of the AC power supply phases connected to the motor windings, which directly impacts the magnetic field and subsequently the shaft's rotation.
Steps to Reverse Three Phase Motor Rotation
If the sequence is altered to L1 → L3 → L2, the magnetic field reverses to a counter-clockwise rotation. Terminal Original Sequence (Forward) Reversed Sequence (Reverse) Terminal A L1 (Yellow) L1 (Yellow) Terminal B L2 (Red) L3 (Blue) Terminal C L3 (Blue) L2 (Red) Identifying the Correct Terminals Before making any changes, it is crucial to confirm the motor's wiring diagram, which is often found on a nameplate or in the documentation.
