Phenix Motor Core Loss Test Sets

The function of a core loss test set is to determine whether a motor has damaged core iron. Damage could include shorts between laminations and damage caused by winding failure. A vital step in the rewinding of a motor is performing a core loss test before the windings are removed to detect any damage to the core. After the windings are removed, the core should be retested to verify that it was not damaged during removal of the old winding. Although it is possible for a motor to still run with core damage, the.

The Doble Engineering Core Loss Test Set is a continuously variable low voltage, high current power supply for testing stators, rotors, and armature cores. These units have very low distortion, independent of load and output setting. This insures test results that are both accurate and repeatable. The basic test set includes complete instrumentation, output and voltmeter cables, computer and printer. The computer is used for complete control, metering, data storage and evaluation of test results. Operation of the.

The operating software interfaces with the test sets Programmable Logic Controller (PLC) that in turn guides the test set through its test functions. The PLC eliminates a large portion of circuitry required in manual test units. With less circuitry, the test set becomes much more reliable and easier to troubleshoot if a problem does occur. Precision control of the output setting is possible with 3-5 ranges per output tap. This translates into 3-5 times greater regulation of the output voltage setting. A meter.
