Dynamometer systems company, Sakor Technologies, has supplied a complete dynamometer test system for electric steering systems manufactured by Hyundai Mobis, the world’s sixth-largest Tier 1 supplier. The dynamometer system will be used by the Hyundai Mobis’ corporate engineering group in South Korea for engineering validation and performance evaluation of electric motors and ECUs that directly control the motor during electric steering.
The test system features a 1.5 kilowatt four-quadrant AC motoring dynamometer and a high-voltage battery simulator which provides repeatable testing for the electric steering components. The testing system communicates with the ECU via CAN bus.
The system validates proper operation of motors and ECUs in electric steering applications and is critical for ensuring that steering operates smoothly, with no perceptible torque ripple felt by the driver.
“With this system they can be assured that motors and controls will operate over their full performance range with absolutely minimal torque ripple,” said Randal Beattie, president of Sakor.
