State-of-the-Art Motor Factory Online Test Bench
Our cutting-edge online test bench for motor factories harnesses the power of an industrial control computer for centralized control. It elegantly completes all test items in one wiring session, integrating the precise measurement of power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. Key benefits include rapid test speeds, high accuracy, ease of use, and exceptional reliability. The system automatically analyzes and judges test results; additionally, it provides comprehensive functions for the statistics, storage, and printing of reports on a yearly, monthly, and daily basis. All motor parameters can be preset for testing.
Key Features:
1. Comprehensive Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, blocked rotor test
2. DC Resistance: Accurately measure the motor winding resistance
3. Insulation Resistance: Precisely test the insulation resistance between the phase wire and the motor shell
4. Inter-Turn Test: Identify inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance conditions in motor or transformer coils
5. Withstand Voltage Test: Measure the leakage current between the stator winding and the shell, with program-controlled and computer-controlled voltage regulation for accurate results
6. No-Load Test: Assess voltage, current, power, power factor, and frequency in no-load conditions (suitable for both single-phase and three-phase motors)
7. Stall Rotor Test: Evaluate voltage, current, power, power factor, and frequency during motor stall conditions (instantaneous start, applicable to both single-phase and three-phase motors)
