It realizes full-parameter closed-loop performance testing of various drive motors, gear reducers, planetary reducers and integrated electric drive assemblies, widely deployed in new energy vehicle factories, industrial automation component manufacturers, home appliance motor labs, third-party testing institutions and university R&D laboratories.

1. New Energy Vehicle Electric Drive Testing Scenarios

1.1 Main drive motor & E-Axle assembly offline inspection

The system simulates real road load conditions through dynamometers. Torque sensors collect real-time output torque, rotational speed and power data to draw motor efficiency MAP, detect peak torque, continuous operating efficiency, temperature rise loss and transmission backlash of integrated electric drive assemblies. It screens defects such as abnormal noise, torque attenuation and oil leakage, serving as the mandatory final inspection station for Tier 1 auto suppliers.

1.2 Auxiliary automotive motor performance calibration

Covers EPS steering motors, water pump motors, air-conditioning compressor motors and electronic brake motors. High-sensitivity miniature torque sensors capture tiny torque fluctuations under low-load conditions, verifying smooth operation and long-term reliability of vehicle auxiliary motors under variable temperature environments.

2. Industrial Servo & Reduction Motor Mass Production Inspection

2.1 Planetary / helical gear reducer factory batch testing

Matched with multi-range torque sensors, the test bench automatically completes no-load current, rated torque output, stall torque, transmission efficiency and fatigue aging cycle tests for servo reduction motors, stepping reducers and robot joint motors. It quickly filters defective products with insufficient output, jitter and excessive noise to guarantee consistent finished product quality on automated assembly lines.

2.2 Heavy-duty transmission equipment durability aging test

For lifting motor, conveyor drive and logistics equipment reducers, the system applies intermittent impact loads and continuous heavy loads for thousands of hours of fatigue testing. Sensors monitor real-time torque decay and friction loss, evaluating the wear resistance of gears, bearings and sealing structures under long-term heavy-duty operation.

3. Small Household & Power Tool Micro Motor Testing

3.1 Household appliance motor energy efficiency certification

Suitable for washing machine variable frequency motors, vacuum cleaner brushless motors, range hood fan motors and food processor drive motors. Micro torque sensing modules measure low-torque power consumption, operating noise and efficiency indicators, supporting energy efficiency grade certification tests in line with national and international standards.

3.2 Lithium battery power tool load simulation test

Simulates cutting, grinding and impact loads of lawn mowers, electric saws and handheld power tools. The test system records peak torque output and power attenuation under high-temperature working conditions, optimizing motor power matching and battery endurance design.

4. Laboratory R&D & Third-party Certification Testing

4.1 University & enterprise motor R&D experiment platform

Supports customizable cyclic load curves for the research of new magnetic resistance motors, high-speed miniature reducers and new energy drive structures. High-precision torque and force sensors output continuous test data for performance analysis, mechanical loss research and structural optimization.

4.2 Authorized third-party testing laboratory

The standardized sensing test bench complies with IEC, GB and automotive industry testing standards. It provides formal type test, energy efficiency inspection and reliability aging reports for motor manufacturers, supporting product export certification and market access review.

5. Aerospace & Precision Special Motor Calibration

For aviation servo actuators, satellite micro reduction mechanisms and medical precision drive motors, ultra-low torque resolution sensors capture micro torque loss under extreme temperature and pressure environments, meeting ultra-high consistency and long-life testing requirements for special-grade power components.

Core Value of Supporting Torque & Force Sensors

Torque transducers accurately capture dynamic rotational torque and speed signals, while pull-pressure load cells detect axial assembly force and axial friction loss of motors. The two types of sensors work together to realize full-dimensional quantitative monitoring of force, torque, power and efficiency, forming the core data acquisition foundation of the entire motor comprehensive test bench system.
