Designing electric motor controls and testing embedded controllers for motor drives is time-consuming, and tests with rotating components and under high-voltage conditions are potentially dangerous. Testing intelligently using digital twins allows for a safe testing environment that not only prevents equipment damage but also personal injury. Furthermore, it provides a continuous workflow across all test phases within a single platform. Development thus becomes faster and more innovative, and errors can be detected early on. […]
