Phase Unbalance: The Hidden Threat to 3-Phase Motors

Most industrial motors are 3-phase. For these motors to run efficiently, the voltage on all three phases must be equal. If there is even a 2% unbalance, the motor's internal temperature can rise by 25%. This is because the unbalance creates 'negative sequence' currents that work against the motor's rotation. VoltApex 3-phase stabilizers feature 'Independent Phase Control,' meaning they correct each phase individually to ensure perfect balance at the motor terminals.
