Mining Flameproof and Intrinsically Safe High-Voltage Variable Frequency Speed Regulation Integrated Machine

The frequency converter and motor are integrated with a detachable and compact structure;

Disconnection function between the frequency converter and motor input/output, enabling quick switch between power frequency and variable frequency modes. Independent operation of both components facilitates easier maintenance；

Advanced NPC Type I three-level topology technology with low output harmonic distortion and reduced voltage reflection; it is more motor-friendly；

New DSP control technology to carry out intelligent online diagnosis of system faults；

Adaptive power balancing for multiple units based on CAN bus without manual intervention;

Overall efficiency ≥95% under full-load and overload conditions；

Multiple protection functions including overload, short circuit, overvoltage, undervoltage, phase loss, phase failure, and power component overheating protection；

Suitable for various operational requirements of scraper conveyors, including soft start, controlled variable-speed or fixed-speed load operation, normal shutdown, emergency shutdown, and forward/reverse rotation control.
