Wolong Nanyang YFB3 series low voltage high efficiency dust explosion-proof asynchronous three-phase AC motor

YFB3 series dust explosion-proof three-phase asynchronous motors are fully enclosed self-fan-cooled squirrel-cage three-phase asynchronous motors. It has the characteristics of small size, light weight, reliable operation, beautiful appearance, etc., and has the advantages of high efficiency, low noise, small vibration, large temperature rise margin, excellent performance, advanced and reasonable explosion-proof structure, safe and reliable use, etc.

Application

Wolong Nanyang YFB3 series dust explosion-proof three-phase asynchronous motors comply with IEC standards, and the motor efficiency reaches IE3 level. It has the advantages of large terminal box volume, improved safety and reliability, increased capacity, frequency conversion capability, and professional appearance design, which greatly improves the market competitiveness of explosion-proof products. The motor explosion-proof level is Ex tD A21 IP65 T130℃; Ex tD A22 IP65 T130℃. It is widely used in food processing, chemical industry, coal mines and other places with explosion-proof dangerous mixtures.
