Variable Frequency Speed Control Training and Assessment Device
This comprehensive VFD motor speed regulation didactic training workbench is designed for vocational and technical college laboratories. The system focuses on practical VFD motor speed-regulation training, covering frequency conversion principles, parameter setting, fault simulation, and skill assessment. Equipped with real industrial components, it enables students to complete hands-on practical training in industrial frequency-conversion control. Widely applied in automation, electrical engineering laboratory teaching, and skill evaluation projects.
