Founded in 2006 and based in Nanjing, I.CH Motion specializes in the R&D, manufacturing, and servicing of electric motors, gearboxes, and high precision small module gears. We focus on micro planetary gear motors and deliver optimized transmission solutions for customers worldwide. Reliable factory testing ensures every motor meets strict performance, durability, and safety standards. This article introduces core test items, professional equipment, and how we integrate customized testing requirements to support your unique applications.
Electrical testing verifies stability under rated and extreme working conditions.
· No load and load voltage/current test: Measure no load current, locked rotor current, and working current under graded loads to check winding consistency and load capacity.
· Winding resistance and insulation test: Use a digital milliohm meter and megohmmeter to confirm resistance uniformity and insulation performance, preventing short circuits or leakage.
· Back EMF test: Use an oscilloscope to measure back electromotive force, evaluating speed linearity and magnetic circuit design.
Mechanical tests validate torque, speed, efficiency, and transmission precision.
· Speed and torque test: On a dynamometer test bench, measure output torque and speed under 25%–100% load to confirm rated performance.
· Transmission efficiency test: Calculate efficiency via input/output power under continuous load, ensuring high precision and low energy loss.
· Backlash test: Measure return clearance with a professional tester, controlling precision within 3–5 arcmin for standard models and ≤3 arcmin for high precision versions.
· Vibration test: Use a vibration analyzer to detect amplitude and frequency, identifying assembly imbalance or gear meshing issues.
These reflect smooth operation and thermal reliability.
· Noise test: In a semi anechoic environment, use a precision sound level meter to measure noise under no load and rated load, typically controlled below 55 dB(A).
· Temperature rise and thermal stability test: Use an infrared thermal imager and thermocouples to monitor housing, winding, and gearbox temperatures during continuous operation, ensuring compliance with safety limits.
· Continuous running test: 8–24 hours of uninterrupted operation under rated load to check performance stability.
· Fatigue and life test: Simulate actual working conditions with repeated starting, stopping, and reversing to verify gear and bearing fatigue life.
· Sealing performance test: For waterproof or dust proof models, conduct IP grade testing to ensure reliability in harsh environments.
· Visual inspection for scratches, deformation, and correct assembly.
· Use a coordinate measuring machine (CMM) to check shaft diameter, gear modulus, concentricity, and fit tolerances.
A complete testing system guarantees accurate and repeatable results.
