The growing adoption of electric motors in the automotive industry and in green energy applications has created new challenges for embedded control system developers and test engineers. Electric motor simulation needs to have high fidelity; HIL (hardware-in-the-loop) test systems must be able to execute simulation models on the order of 1 µs to adequately simulate the electric motor behavior. This combination of simulation fidelity and execution speed has previously been impossible; many test engineers had to rely on more costly dynamometer or field testing to validate their embedded software. 

Using the latest technology for real-time high-fidelity electric motor simulation, you can test many types of transient and fault conditions that are difficult or impractical to perform with real systems. These tests can be destructive to physical hardware. However, with this highly accurate simulation of the physical system, you can exercise the controller at corner cases to ensure real-time safety and security. 

The National Instruments HIL platform provides the highest fidelity real-time simulation available in an open, extendable platform for test execution. With the NI platform, you can find problems and optimize performance at an earlier stage of the development process, which reduces the amount of field testing for validating embedded software and, as a result, improves development efficiency.
