NI collaboration with JSOL delivers JMAG-RT add-on for HIL modelling

National Instruments has introduced the JMAG-RT add-on for NI VeriStand, which gives engineers the same fidelity provided by JMAG models, but in real-time for hardware-in-the-loop (HIL) testing of electric motors. The 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 to reduce spending on field-testing physical motors.

The add-on makes it possible for automotive engineers to perform high-fidelity, real-time simulations of electric motor prototypes without testing costly physical motors. It is suitable for helping automotive manufacturers developing electric and hybrid motors and engine control units (ECUs) to get their products to market quickly and with less cost.

Features:

1. Integrated with Xilinx FPGA-based hardware/software to deliver high-fidelity simulations with approximately 1 microsecond step times.
2. JMAG finite element analysis (FEA) electric motor models from JSOL integrate with NI VeriStand and NI reconfigurable I/O (RIO) hardware.
3. NI's complete HIL systems can be configured for real-time motor or ECU test scenarios.

"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."
