Eliminate Voltage Unbalance

Voltage unbalance degrades the performance and shortens the life of a three-phase motor. Voltage unbalance at the motor terminals can cause current unbalance that is far out of proportion to the voltage unbalance. Unbalanced currents lead to torque pulsations, increased vibrations and mechanical stresses, increased losses resulting [...]

How to Completely Test 3-Phase AC Induction Motors Using Deenergized Motor Testing

People often conduct motor inductance testing with methods that don’t accurately assess the whole picture. Inadequate testing can lead to premature equipment replacement, poor cost analyses and other negative outcomes. Deenergized motor testing with ALL-TEST Pro’s proprietary Motor Circuit Analysis (MCA™) devices can make testing more accurate, [...]
