YFB3 series dust explosion-proof motor

In the industrial production process, many solid combustible dusts are often produced. In addition to coal (coal, activated carbon), there are also metal processing (aluminum, magnesium, titanium, etc.), agricultural and sideline products processing (flour, cocoa, cotton dust, flax, Fiber), chemical raw materials, synthetic materials (plastics, resins, fuels, etc.), chemicals (sodium acetate, aspirin, zinc stearate, etc.), where the electric drive in these industries and sectors requires dust explosion-proof motors. YFB3 series dust explosion-proof three-phase asynchronous motor (hereinafter referred to as the motor) is a squirrel cage three-phase asynchronous motor, and its explosion-proof performance of the motor conforms to the GB12476.1-2013 "Electrical Equipment for Combustible Dust Environment Part 1: General Requirements" and the GB12476.5-2013 "Electrical Equipment for Combustible Dust Environment Part 5: Shell Protection" tD ". The electrical performance of the motor meets the requirements of Q/320205BABD21-2014 Technical Conditions for YFB3 Series Dust Explosion-proof Three-phase Asynchronous Motors (Block No. 63-355). There are two types of enclosure protection grades: IP55 for dustproof type and IP65 for dust-tight type. Explosion-proof marks are ExtD A21 IP65 T130℃ , ExtD A22 IP55 T130℃ , ExtD B21 IP65 T130℃ , ExtD B22 IP55 T130℃
