New energy motor drive test bench

This is a modular, high-precision integrated test system designed for new energy vehicle drive motors and controllers. It simulates real-vehicle load, battery input, and road cycles to complete performance verification, reliability validation, calibration, and quality inspection of electric drive systems.

Core composition

Loading & dynamometer system: High-speed dynamometer for four-quadrant operation, precise torque/speed/power measurement.

Power supply & simulation: Regenerative bidirectional DC power / battery simulator, supporting energy feedback to grid.

Measurement & control: High-speed power analyzer, sensor array, real-time controller for automated test sequences.

Cooling & safety: Constant-temperature cooling, overcurrent/overtemperature/short-circuit protection, EMC compliance.

Key functions

Performance test: Efficiency MAP, torque-speed characteristic, locked-rotor, loss analysis.

Durability & reliability: Long-duration running, thermal cycle, vibration, and service-life evaluation.

Development calibration: Dynamic response, control strategy optimization, drive system matching.

Quality & certification: Batch consistency inspection, compliance with GB/T 18488, ISO, IEC standards.

Features

Modular & flexible for various motor types (PMSM, IM, reluctance motors).

High accuracy & repeatability with closed-loop control.

Energy-saving regenerative design lowers operating cost.

Automated data acquisition, report generation, and HIL compatibility.

Application

Suitable for R&D, production, and certification labs of new energy passenger/commercial vehicles, engineering education, and third-party testing institutions.
