Product Introduction

The YJVFG Series Flame-proof and Intrinsically-safe High Voltage Motor with Integrated VFD for Mining Applications is a combination of a VFD and a motor, for use with AC 3300V 50Hz power supply systems. With its high starting torque and load balancing capability, the device can carry out smooth start-up, speed regulation, stalling and other functions in a variety of load conditions, completely eliminating any mechanical or electrical impact, and extending the service life of the customer's mechanical equipment. The product features a hot-line and operating state display HMI, designed with overload, overvoltage, undervoltage, open-phase and overheating protection functions.

The YJVFG Series Flame-proof and Intrinsically-safe High Voltage Motor with Integrated VFD for Mining Applications ("Motor with Integrated VFD" for short) is suitable for coal mines with methane and coal dust in the air. It can be used to efficiently deliver power to coal mine armored face conveyors, beam stage loader, crusher, belt conveyors and other transportation equipment, saving energy and reducing operating costs.

 

Product Highlights:
1. High starting torque, with overload capacity greater than 2.5 times the rated power (2.5×FLT), suitable for frequent heavy-load starting conditions;
2. Compact design, suitable for driving armored face conveyors and beam stage loaders in longwall mining systems, as well as workplaces with extremely high requirement for installation dimensions;
3. No filters and reactors needed for long-distance variable frequency power supply;
4. Eliminating harmonic interferences caused by long-distance variable frequency power supply to the power grid;
5. High efficiency, high power factor, basically maintenance free, saving operation costs.

 

Typical Applications:
1. Armored Face Conveyor;
2. Beam Stage Loader (crushers);
3. Belt conveyor;

4. Emulsion pump station.
