Ex-Proof Motor Yb3 Series 185kw 6p
YB ranges of three-phase induction motors are flame-proof and conventional motors obtained by renewal and generation-changing of YB motors. The performances of the products have come up to advanced international standards.
The motors have the advantages of higher efficiency, energy saving, higher locked-rotor torque, lower noise, smaller vibration, safe and reliable operation and beautiful appearance, etc...
The outputs, mounting dimensions and their corresponding relationships comply with IEC standards.
YB2 range of motors comply with GB3836.2, Electrical Apparatus for Use in Explosive atmosphere part 2: Flame-proof Enclosure 'd'. The flame-proof constructions and their parameters have referred to IEC60079-1, Construction and Verification Test of Flame-proof enclosure for Electrical Apparatus, and EN50018, Electrical Apparatus for Use in Explosive atmosphere: Flame-proof Enclosure 'd'.
The motors are made into flame -proof type, and are suitable for use in explosive gas atmosphere, which can be divided into two groups. Group I is used for coal mine and marked with Exd I; Group II is used for explosive gas atmospheres other than coal mine and marked with Exd II; AT11-T4 Exd II BT1-T4 and Exd ECT1-T4(temperature class T1-T4 meansT1, T2, T3, and T4).
Degree of protection by enclosure of motor is IP54 and IP55. The frames of motors are designed with parallel cooling ribs which are distributedvertically and horizontally. The stator windings of the motor are class F insulated.
