Motor Stator Test System
The motor stator test system leverages an advanced industrial control computer for centralized management, enabling the completion of all test items through a single wiring. This streamlined process rapidly evaluates parameters required by national and enterprise standards, such as power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. This system is renowned for its exceptional test speed, high precision, user-friendliness, and outstanding reliability. It not only automatically analyzes and assesses test results but also features comprehensive functions for statistical analysis, storage, and the printing of yearly, monthly, and daily reports. Moreover, it allows for the presetting of all motor test parameters, ensuring thorough and accurate testing.
Key Features:
1. Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC Resistance: Measures the resistance of the motor winding.
3. Insulation Resistance: Assesses the insulation resistance between the phase wire and the shell.
4. Inter-turn Test: Identifies inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance issues in the motor or transformer coil.
5. Withstand Voltage Test: Measures the withstand voltage leakage current between the stator winding and the shell. Features programmable control for withstand voltage, which can also be regulated by computer.
6. Motor Steering: Determines the direction of the magnetic field rotation.
7. Inductance Test: Measures the inductance of the motor coil.
8. Power Supply: Requires AC220V±15%, 50Hz±2 Hz (system working power supply).
9. Operating Environment: Suitable for working temperatures ranging from 0 to 40 °C.
10. Working Humidity: ≤70%.
11. All tests are completed with a single clamping mechanism.
12. All testing processes are microcomputer-controlled.
