Product Introduction

The Flame-proof and Intrinsically-safe AC VFD for Mining Applications is a leading product, suitable for AC motor frequency control in coal mines and other explosive environments containing coal dust or gas. The product is suitable for asynchronous and permanent magnet synchronous motors. The specialized VFD for mining applications uses world-class core components, and features a modular design based on the characteristics of the flame-proof box in combination with the working conditions of a coal mine. With its high starting torque and high precision in speed control, the device is energy saving, efficient, safe and reliable. It can be widely used in coal mine hoists, belt conveyors, armored face conveyors, beam stage loaders, fans, pump stations and other equipment.

Technical Characteristics

Advanced SVPWM space vector PWM modulation

High output torque: 150% of rated torque can be reached at 0.5Hz, with maximum torque output up to 200%

Low-speed high torque

Stable operation at ultra-low speeds at 0.1Hz; the low torque ripple characteristic keeps the torque deviation within 3% through vector control

High-precision self-learning technology

Accurately identify motor parameters, and achieve high-performance vector control

High-speed output using vector control

Highest frequency up to 200Hz

Excellent over-current suppression and over-voltage suppression functions

Avoiding frequent protection shutdowns, and to meet the requirement of complex working conditions

Suitable for power supply conditions in coal mines

Rated voltage fluctuation range is allowed to be -15% ~ +10%
