YB2-90 a series of explosion-proof motor, YB2-90 series of explosion-proof motor classification YB2-90S series also follow explosion proof motor motor frame size and power to divide, YB2-90 explosion-proof motor size L and S have two kinds. Concrete proof motor models: YB2-90S-2 (1.5KW) flameproof motors (2-pole 1.5W explosion-proof motor), YB2-90S-4 (1.1KW) flameproof motors (4-pole motor 1.1KW proof), YB2-90S-6 (0.75KW) flameproof motors (6-pole motor 0.75KW proof), YB2-90L-2 (2.2KW) flameproof motors (2-pole 2.2KW explosion-proof motor), YB2-90L-4 ( 1.5KW) flameproof motors (4-pole motor 1.5KW proof), YB2-90L-2 (1.1KW) flameproof motors (2-pole 1.1KW explosion-proof motor). Two, YB2-90 series flameproof motor Model meaning: Y: induction motor; B: representation is flameproof motor; 2: Indicates the number improved design; 90: Indicates the distance from the center axis of the ground; YB2-90 series flameproof meaning motor representatives proof mark: Ex: Flag (explosion); d: explosion-proof electrical equipment type (flameproof); ⅡB temperature class (T4); T4 electrical equipment category level (Ⅱ Class B grade) three YB2-90 series of explosion-proof motor Overview YB2-90 series flameproof motor is totally enclosed fan-cooled three-phase squirrel cage induction motor flameproof advantages: a, energy efficient b, temperature margin large c, long life d, performance Well, f, small vibration, high reliability e, flameproof advanced structure and easy maintenance, this series of explosion-proof motor performance in line with GB3836.2-2001 <> and the International Electrotechnical Commission standard IEC79-1 provisions were made of flameproof Exdl, ExdllAT4, ExdllBT4 applicable to non-coal mines and factories have color Driving Faces IIA, IIB group explosive gas mixture temperature T1-T4 group exists dangerous places YB2 Series main enclosure protection class IP55 This series motor cooling method is IC411.
