rotation directioncalibrationcurrent

Product introduction:
The UHV-316D stator test bench is designed for production and workshop testing of single-phase and three-phase generator stators. It measures 3-, 6-, 9- and 12-wire windings using a 2‑channel wiring method and is suitable for new energy motor stators up to frame H355.

Standard test items:

• DC resistance test
• Insulation resistance test (DC 500 V)
• Inter-turn insulation test
• Power-frequency withstand voltage test
• Winding current balance test
• Rotation direction test

Optional test items:

• Inductance test
• Current balance test
• Magnetic field rotation direction test

Product features:

• Comprehensive result display with simultaneous presentation of all test results, built-in data storage and printout functions
• Foot-operated safety switch for safe and reliable operation
• Front-end test fixture configured for medium and small stators, supporting single- and three-phase testing
• High-speed measurement suitable for high-volume production (e.g., appliance and water-pump motors)
