E-Mobility Enhanced Driveline Test System (T-Rig)


Link Engineering Company’s E-Mobility Enhanced Driveline test system provides a wide range of motor measurement and characterization capability. This system combines a high-performance axle dynamometer with a motor analyzer and an array of precision instrumentation for complete electric motor drive system analysis. The test system may be operated manually or automatically to perform a sequence of automated tests and measurements.

Component isolation contactors and switches are included, so that the drive system under test may be tested as a complete system or broken into the individual drive system components: motor, motor inverter/motor controller, and power source/battery, for component level measurements such as motor winding resistance or open circuit battery voltage. The system is designed to allow component level tests to be performed with an automated sequence of system level testing.
