A complete dynamometer testing system for electric steering systems has been supplied to Hyundai Mobis, the world’s sixth largest Tier 1 supplier, by SAKOR Technologies. The dynamometer system will be used by the corporate engineering group in South Korea for engineering validation and performance evaluation of electric motors and electronic control units (ECUs) that directly control the motor during electric steering.
The SAKOR system supplied features a 1.5 kilowatt 4-quadrant AC motoring dynamometer. Also included is a high voltage battery simulator which provides repeatable accurate testing results for the electric steering components. The testing system communicates with the ECU via CAN bus (Controller Area Network).
Running a full suite of testing applications, the SAKOR dynamometer testing system validates proper operation of motors and ECUs in electric steering applications. The system is critical for ensuring that steering operates smoothly, with no perceptible torque ripple felt by the driver.
“We are very pleased to provide Hyundai Mobis with this very precise system for conducting vibration and resonance testing on designs for the entire line of electric steering systems,” said Randal Beattie, president of SAKOR. “With this system they can be assured that motors and controls will operate over their full performance range with absolutely minimal torque ripple.”
