The electric scooter motor dynamometer is a high-precision power performance testing device specifically designed for the drive motors of electric scooters (brushless/brush motors). By simulating real load conditions, it accurately measures the torque, speed, power, efficiency and temperature rise characteristics of the motor, comprehensively evaluating its power output stability and energy consumption performance. This equipment is widely used in motor research and development, production quality inspection, vehicle matching and certification institutions, ensuring that products comply with international standards such as ISO 19453, GB/T 18488, and UL 2272, providing a scientific guarantee for motor performance optimization and reliability.
Application scope
Used for electric scooter motor dynamometer testing.
Core functional modules
Dynamic performance testing
Torque/Speed Precise Measurement:
1. Torque range: 0~50N·m (accuracy ±0.1% FS), speed range: 0~10,000rpm (accuracy ±0.01%), plot motor MAP diagram (efficiency-torque-speed relationship).
2. Support constant torque, constant speed, and constant power modes, simulate scenarios such as climbing, acceleration, and cruising.
Temperature Rise and Thermal Management Testing:
Real-time monitoring of winding temperature (accuracy ±1℃), record temperature rise curves, verify the effectiveness of heat dissipation design.
Environmental Coupling Testing
Temperature and humidity simulation (optional): temperature range -40℃~+120℃, humidity 10%~95% RH, test efficiency attenuation and start-up performance under extreme environments.
Vibration Durability Testing (optional): random vibration (5~500Hz, acceleration 10g) simulates the impact of bumpy road conditions on motor structure.
Intelligent Analysis System
Energy Efficiency Evaluation: calculate motor efficiency (η), input/output power ratio (accuracy ±0.2%), identify energy consumption bottlenecks.
Failure Warning: AI algorithm analyzes harmonic distortion (THD), current surges, and other anomalies to predict risks of bearing wear or winding insulation aging.
