DZ901 Motor Stator Tester (scanning type)

Appearance Reference Scan Screen Application Case
Scope
Applicable to precision electrical properties test of stators of △/Y-type three-phase motors, single-phase motors, hub generators, brushless motors and servo motors
Functional Features
● Proprietary slot by slot precision scanning and coil detection function; judgment threshold can be set for stators automatically; detect wiring errors, outgoing wire errors, wrong embedding in slots, partial de-embedding, number of turns out of tolerance, give alarm in case of test data over-limit, and provide fault information to facilitate repair.
● Stator insulation resistance, HIPOT, coil DC resistance, turn to turn surge tests and wrong winding in coil units can be automatically completed in one time
● Enable or disable any test items, set pass criteria; release automatic light or sound alarm upon test result over-limit
● It is not required to set the instrument measurement range; even an ordinary operator can sample a motor stator with its parameters unknown very easily and formulate the automatic judgment criteria; test results immune to ambient temperature
● Unique automatic range switching and test tracking; therefore a higher accuracy than other similar instruments throughout the measurement range. It is not required to set the instrument measurement range as the stator coil resistance range is not required to know beforehand; even an ordinary operators can sample a stator with its parameters unknown very easily and formulate the automatic judgment criteria
● Inter-phase resistance balance test function; automatically identify slight difference in coil resistance resulting from inner and outer layer winding process although some three-phase motor windings are the same in the number of turns, thereby more accurately analyzing the coil turns errors or slight difference in enameled wire diameter; more powerful winding error and fault identification capabilities
● Automatic, multiple-wave judgment of turn-to-turn surge test between any bars under any form of surge, any times of surge; observe abrupt change in rising edge and wave crest, and automatically discover coil turn to turn insulation defects
● HIPOT, turn to turn surge test voltage settable, automatically generated and regulated; test data immune to fluctuations from external grid; offset the inherent leakage current of test system automatically; monitor and check the effectiveness of HV test automatically
● Immune to stator high-voltage breakdown ignition in the test process, the instrument can work stably and reliably
● Save, edit and call the automatic judgment criteria for stators of different models or specifications; with no quantity limitations
● Powerful data management function; can automatically number each stator, check the test result and graph for each model and stator, and generate statistics reports; reports can be exported via a USB disk
● Single-station/double-station optional, high practicality and test efficiency
● Modify technical specifications, add functionalities, design and manufacture test tooling based on order requirements
