Core Loss Testers

The LEXSECO® Core Loss Tester provides highly accurate, waveform-independent readings by utilizing high resolution flux, current, and power measuring devices for the core being examined.

The Core Loss Tester includes a Variable Reactance Transformer (VRT) with solid state controls, a digital metering package, computer system, and test cables with quick connecting fittings.  Safety fuses, over-temperature protection, interlocks, surge suppressors, and circuit breakers are present to provide maximum protection to the hardware and operator.

The Core Loss Tester provides an adjustable output current from 0 to 2,000 amperes for some models and up to 4,000 for others.  The VRT used by LEXSECO® provides ease of control and self-limiting current, both of which offer tremendous advantages over other sources of power used in the industry.

Your LEXSECO® Core Loss Tester is designed to be used with LEXSECO® MP 7TM software.  This highly refined combination of software and hardware will ensure accurate results.  Please refer to the software and computer manuals for more information.

Armature Testing Kit

When testing wound rotors and armatures, the following test method should be employed:

 

If the shaft is removed or adequate space exists for the main cable to pass through the rotor, the rotor test should be implemented in the same manner as the stator test would be performed.  Otherwise, use the LEXSECO® rotor shaft clamps to clamp onto the rotor shaft and use it as the current path through the rotor.  Perform core loss test as specified in the test instructions and compare the results of the test to any tests performed on nearly identical rotors when possible.

Magnetic Paper

The LEXSECO® magnetic paper is a micro-encapsulated film that reacts to the presence of a magnetic field.  The film aligns with the magnetic lines and permits the user to view an electric motor's static magnetic field which can identify problems with its construction and integrity.
