1. Product introduction Permanent magnet synchronous reduction motor has the advantages of simple structure, small size, high efficiency and high power factor. Permanent magnet synchronous reduction motor adopts concentrated winding, optimal pole slot matching, and a rotor structure that integrates magnetic isolation, force and light weight. The motor has the characteristics of small rotational in...

Product Introduction This series of products are mainly used in coal mines and other explosive gas environments containing methane and coal dust mixtures in AC 50Hz voltage 1140V or 660V or 380V three-phase neutral point ungrounded lines to control the start and stop of three-phase asynchronous motors locally or remotely, and can perform reversing when the motor is stopped. (Models with N can cont...

Introduction In the mining and bulk material handling industries, belt conveyors are the backbone of efficient material transport. One critical component that ensures smooth operation is the tensioning system, which maintains optimal belt tension to prevent slippage, reduce wear, and improve energy efficiency. Traditional tensioning methods—such as hydraulic, counterweight, and screw tensioning—ha...

Introduction In underground mining operations, electrical safety is non-negotiable. Harsh environments—filled with flammable gases, dust, and moisture—demand robust protection against explosions and electrical faults. This is where Expolsion-Proof Intrinsically Safe Permanent Magnet Vacuum Feed Switch come into play. These advanced switching devices combine flameproof enclosures (Ex d) with intrin...
