Product Description Explosion Proof Roller of Conveyor BeltProduct introductionMining flameproof three-phase permanent magnet synchronous electric drum (hereinafter referred to as permanent magnet electric drum) is a new low-speed and high torque external rotor permanent magnet motor independently developed by Wantai, commonly known as permanent magnet electric drum. Together with special frequency converter, control system and cooling device, it forms an intelligent permanent magnet external rotor frequency conversion direct drive system, which can realize stepless speed regulation in a wide range.Permanent magnet electric roller has changed the complex transmission chain of traditional belt conveyor, which is composed of motor + coupler + reducer + coupler + transmission roller. It integrates drive, transmission and roller, and brings a revolutionary change of belt conveyor drive system.The permanent magnet electric drum fully considers the requirements of driven equipment, frequency converter and control system in the speed regulation process. It has the advantages of low speed, high torque, wide speed regulation range, anti frequency converter DV / dt high-frequency pulse harmonic, high efficiency and energy saving, low noise, long service life and high reliability. It is an ideal driving product for bulk material transportation machinery.Technical parametersRated working voltage: AC 660 / 1140VRated output power: 55 ~ 315KWNumber of electric roller poles: 60 or 24 polesRated output belt speed (M / s): 2 ~ 5Bandwidth (mm): 800 ~ 1600Cooling mode: water coolingInsulation grade of electric drum winding: Class HExplosion proof type: Exd I MBTechnical advantages and main features1. High quality cladding treatmentThe cladding is diversified and can be made of flame-retardant rubber, polyurethane, ceramics and other materials to meet the requirements of MT / t962-2019 cladding for coal mine belt conveyor drum2. Compact installation spaceIntegrated, permanent magnet drum = motor + hydraulic coupling + reducer + coupling + drum3. Energy saving and high efficiencyThe mechanical transmission efficiency is 100%, with high efficiency and high power factor4. Reliable insulation systemVPI vacuum dipping technology is adopted, which has high electrical strength, high mechanical strength, corrosion resistance and moisture resistance. The winding adopts f / H insulation to ensure reliability5. Reliable bearing structureDouble row self-aligning bearing is adopted to ensure service life of more than 50000 hours6. Comprehensive monitoring and protectionStandard temperature measuring device, optional temperature field display table, temperature transmitter and vibration sensor to meet field requirements.
