The motor test bench under UHV power can help many power workers conduct various power tests more conveniently.
motor testing can be simplified into the following core steps:
1. Define Goal & Prepare
Purpose: Is it for R&D validation, production quality inspection, or troubleshooting?
Parameters: Know key specifications like rated voltage, current, power, and speed.
Tools: Prepare power supply, load (e.g., powder brake), dynamometer, power analyzer, thermocouple, oscilloscope, etc.
2. Basic Tests (Mandatory)
Safety & Mechanical Check: Check insulation resistance, winding resistance, appearance, and smoothness of rotation.
No-Load Test: Run without load. Measure no-load current and speed to check for abnormalities.
Load Test: Apply load. Measure core performance metrics like torque, speed, power, efficiency, and plot characteristic curves.
3. Key Tests (Optional, based on needs)
Temperature Rise Test: Run until thermally stable, measure winding temperature, and evaluate heat dissipation design.
Dynamic Test: Test startup characteristics, speed regulation response, control accuracy, etc.
Endurance/Life Test: Long-term or accelerated testing to assess reliability and lifespan.
4. Analysis & Summary
Compare test data with standards or design targets, generate a test report, and determine if the motor passes.
The Core Purpose: All tests are to verify if the motor's performance meets specifications at its "rated point"
