FAQ

What types of motors can this stator tester be used for?

This three-phase motor stator tester is designed for testing a wide range of motor stators, including small and medium-sized three-phase motors as well as single-phase single-speed motor stators. It is suitable for quality control, production lines, and laboratory testing environments.
What tests can be completed with a single wiring connection?

With one-time wiring, the tester can complete multiple tests in one station, including AC Hi-pot (phase-to-phase and to ground), insulation resistance, surge (inter-turn withstand voltage), Coil resistance, and optional partial discharge (PD) testing. This significantly improves testing efficiency and reduces operation errors.
How does the tester ensure accuracy and consistency of test results?

3.The tester uses digital closed-loop feedback control and automatic voltage regulation, which compensates for power grid fluctuations. It also monitors ambient temperature in real time and automatically converts resistance test results to standard temperature values, ensuring accurate, consistent, and repeatable test results.
