HIL Testing of Electric Motors

06 July 2012 – National Instruments introduced the JMAG-RT add-on for NI VeriStand, which gives engineers the same fidelity provided by proven JMAG models, but in real-time for hardware-in-the-loop (HIL) testing of electric motors. To reduce spending on field-testing physical motors, engineers can use NI VeriStand with the JMAG-RT add-on in the lab to easily create stimulus profiles and perform data logging and automated HIL testing with real-time electric motor simulation.

“When engineers use the JMAG-RT add-on for NI VeriStand, which combines NI VeriStand software and NI RIO hardware with our JMAG-RT modeling, they get the world’s most advanced platform for real-time electric motor simulation,” said Dr. Takashi Yamada, manager of electromagnetic engineering at JSOL. “The system helps expand engineers’ test coverage while saving time and money because they now can perform ECU testing without risking damage to expensive prototype motors.”

Product Features

•             Xilinx FPGA-based hardware/software integration delivers high-fidelity simulations with approximately 1 microsecond step times to increase measurement speed and accuracy.

•             JMAG finite element analysis (FEA) electric motor models from JSOL integrate with NI VeriStand and NI reconfigurable I/O (RIO) hardware.

•             NI’s complete HIL systems can be configured for most real-time motor or ECU test scenarios.
