    Complete Motor Health Assessment

    The electrical health of all motor components is evaluated, including, but not limited to induction windings, rotors, DC field windings and armature, field and rotor coils in synchronous motors, primary and secondary windings in transformers, and all associated connections and cables.

    Patented Test Value Static™ (TVS™)

    Test Value Static (TVS) is a sum calculated from the 3-phase MCA static test and is used as a reference value for the motor. Common types of faults in the rotor and stator windings will change TVS.

    Patented Dynamic Stator and Rotor Signatures™

    Used to evaluate the condition of the stator and squirrel-cage rotor in a single test. Perfect for testing new and repaired motors prior to acceptance.

    Beyond Traditional Induction Motor Testing

    With our ALL-TEST PRO 7™ Professional, you can use our patented Stator and Rotor Signatures™ to test the squirrel-cage rotor and stator with a single assessment. You can also diagnose common fault types using this product’s patented Test Value Static™ (TVS™), which provides a sum calculated from a 3-phase MCA static assessment.

    This product tests every AC motor type. It evaluates the electrical health of synchronous, single-phase motors by assessing their stator wings, rotors, cables and other components.

    With the high-tech capabilities of the ALL-TEST PRO 7™, you and your technicians can easily detect even the most subtle imbalances in any motor. Maximize your investment by:

    • Testing installation and startup of new motors
    • Testing motor spares, transformers & generators
    • Troubleshooting problematic motors
    • Ideal tool for PdM testing program
