The 8-Station Hub Motor Life Test Bench is specifically designed for endurance testing, reliability verification, aging evaluation, and performance characterization of electric bicycle hub motors.

The system enables simultaneous testing of up to eight hub motors, significantly increasing laboratory efficiency and reducing validation time. Each workstation operates independently, allowing different loading conditions, torque profiles, and test cycles to be executed simultaneously.

A magnetic powder brake loading system combined with high-precision torque sensor feedback provides accurate closed-loop torque control, ensuring stable and repeatable load simulation throughout long-term durability testing.

The equipment is ideal for hub motor manufacturers, electric bicycle OEMs, research institutions, certification laboratories, and quality control departments.
