Using the Derui 8-Station Hub Motor Life Test Bench is a streamlined process for obtaining high-quality endurance data. Here’s how it works:
Motor Mounting & Connection: Up to eight hub motors are securely mounted onto the dedicated test fixtures. Each motor's phase wires and hall sensor connectors are plugged into the corresponding station's measurement and control interface.
Parameter Setup & Profile Creation: Using the intuitive PC software, the operator defines the test profile for each station (or applies a common profile). This includes setting speed ramps, load (torque) levels, cycle counts, and safety limits (max temperature, current).
Automated Test Execution: The test is initiated. For each station, the control system powers the motor and applies the programmed load profile via the dynamometer. The system simulates real-world conditions, such as a motor powering a bike up a hill (high torque, low speed) or cruising on a flat road (constant speed).
Real-Time Data Acquisition & Monitoring: Throughout the test, sensors at each station continuously monitor voltage, current, speed, torque, and temperature. The software displays this data in real-time, allowing operators to monitor the health of all eight motors simultaneously.
Failure Detection & Automated Shutdown: The system's logic constantly compares live data against the defined safety limits. If a parameter exceeds its threshold (e.g., a bearing seizes, causing a current spike), the system automatically cuts power to that specific station, isolates the fault, and logs the event, protecting the other seven tests from interruption.
Data Logging & Report Generation: All performance data is automatically logged at a user-defined frequency. Upon test completion (or after a failure), the system can generate comprehensive reports, including efficiency maps, temperature rise curves, and a log of any anomalies, providing invaluable data for engineering analysis.
This blend of parallel testing, precise load control, and continuous monitoring ensures your hub motors undergo rugged, valid testing that meets global standards and supports both quality assurance and advanced product development.

What types of hub motors can be tested?
The bench is designed to test a wide variety, including geared hub motors, direct-drive hub motors, for both front and rear wheel applications. It can accommodate motors of different sizes, power ratings (e.g., 250W, 500W, 1000W), and voltage configurations with the appropriate fixtures and software setup.
How long does a typical life test take?
The duration is fully customizable. A standard life test might run for hundreds of hours or millions of cycles to simulate years of use. The actual time depends on the test profile (e.g., continuous vs. intermittent duty) and the specific endurance targets defined by the manufacturer or relevant standards.
Can the bench simulate real-world conditions like hill climbing?
Yes, absolutely. This is a core feature. The multi-quadrant dynamometer allows the system to apply a precise, programmable load profile. You can program the test to simulate the high torque required for hill climbing, the constant speed of cruising, and even the regenerative braking effect when going downhill.
What happens if one motor fails during a test?
Each of the 8 stations is independently monitored and controlled. If a motor exceeds a safety limit (e.g., over-current, over-temperature), the system will automatically shut down only that specific station. The test will continue uninterrupted on the remaining seven stations, maximizing testing efficiency.
What are the maintenance requirements?
Routine maintenance is straightforward and focuses on the dynamometers (periodic lubrication/cooling checks), sensor calibration (annually recommended), and software updates. The system is built with industrial-grade components for long-term reliability. Derui provides comprehensive after-sales support and calibration services.
