The MCEmax is a revolutionary tester, combining the capabilities of the MCE and the Emax into one portable package. By integrating these two technologies, PdMA has created the single most powerful motor testing
tool available. Regardless of the size, type or condition of your motors, the MCEmax provides the flexibility needed to get the job done.
Every facet of the motor can be evaluated, from the power quality, power circuit and insulation to the rotor, stator and air gap.
Power Quality - the power being fed to your motor is in reality the food it needs to operate efficiently. MCEmax monitors three phases of voltage and current and will alert you when an unhealthy condition exists.
Power Circuit - all connections, components and cables between the MCC and the motor must be resistively balanced. Potential problems occur when you introduce loose or corroded connections into the circuit. The
MCEmax compares each phase of resistance, current and voltage to ensure a perfect balance.
Insulation - resistance-to-ground values for motor windings decrease as moisture and contamination increases. The MCEmax not only provides
testing capabilities up to 5000/VDC but also offers continuous graphing polarization index and computer automated step voltage tests.
Rotor - identify cracked/broken rotor bars, porosity and high resistance connections in the end rings thru motor current signature analysis (MCSA) and the rotor influence check.
Stator - phase-to-phase resistance, inductance, impedance and current imbalances are used to determine turn or phase shorts as well as faulty
internal connections.
Air Gap - bowed shafts, cocked end rings or degraded journal bearings create magnetic imbalances. These magnetic imbalances show up as 1st and 3rd sidebands around eccentricity frequency or as a "bow tie" shape on
the rotor influence check.
Never before has such comprehension and flexibility been available in one tester.
