| Motor Stator Comprehensive Performance Test System for Power Tools |
Motor stator test system
The Motor Stator Test System harnesses the power of an industrial control computer for centralized management, streamlining all test items through a single wiring setup. This efficient system swiftly evaluates national and enterprise mandatory inspection parameters such as power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. Boasting unparalleled speed, precision, user-friendliness, and reliability, it automatically analyzes and judges test results. Additionally, it features comprehensive functions for statistical analysis, storage, and the printing of yearly, monthly, and daily reports. All motor parameters under test can be pre-configured for optimal 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: Precisely measure the resistance of the motor winding.
3. Insulation resistance: Accurately test the insulation resistance between the phase wire and the casing.
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: Assess the withstand voltage leakage current between the stator winding and the casing, with programmable control and computer-regulated voltage settings.
6. Motor steering: Determine the direction of the magnetic field's rotation.
7. Inductance test: Measure the inductance of the motor coil with precision.
8. Power supply: AC220V±15%, 50Hz±2 Hz (system operational power supply).
9. Operating environment: Functional within temperatures of 0~40 °C.
10. Working humidity: Up to 70%.
11. Comprehensive testing: All tests are completed with a single clamping.
12. Advanced control: All testing processes are governed by a microcomputer.
