Typically, three line wires—representing the three phases—are connected to the respective terminals. Testing and Verification After reconfiguring the wiring, the motor should be powered up briefly and observed carefully.
Dual Voltage Motor Direction Reversal: Switching Wiring for Opposite Rotation
Misidentifying terminals can lead to short circuits or failure to start. This orderly progression creates a magnetic field that spins clockwise, for example.
This field is created by the alternating currents flowing through the three separate windings, which are spaced 120 electrical degrees apart. The connection terminals at the motor's terminal box are then accessed.
Reversing Rotation on a Dual Voltage Motor by Reconfiguring Line Wires
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.
