YB2 Series Flameproof Three-Phase Asynchronous Motor
Product Overview:
1.1, YB2 series flameproof three-phase asynchronous motor is our country in the Y2 series (IP54) three-phase asynchronous motor on the basis of a series of YB series flameproof three-phase asynchronous motor replacement products. It has the international advanced level in 90s. This series motor has the advantages of beautiful appearance, higher protection level than YB series, more safe and reliable. At the same time better starting performance, noise and vibration lower than the YB series. The utility model can be suitable for the use of explosive gas mixture in coal mine underground (non mining working face and factory).
1.2, YB2 series three-phase asynchronous motor, strict implementation of standard JB/T7565.1 -2004 "YB2 series flameproof three-phase asynchronous motor technical conditions" and made explosion-proof certification organization from the production of a full range of 63~355 a total of 15 frame, power from the 0.12~315kw1 17 specification. The factory currently has a total of 13 63~280 seat number, power from 0,12~90kw a total of 82 specifications.
1.3, YB2 series flameproof three-phase asynchronous motor characteristics:
1) YB2 series flameproof three-phase asynchronous motor has a high degree of standardization, universal power rating of a full range, the installation size and YB series is basically the same, with a certain degree of inheritance.
2) The motor has a unique parallel vertical fin shape structure, which not only increases the heat dissipation area, but also increases the aesthetic feeling of the motor.
3) The motor is f class insulation, but its temperature rise (resistance method) still according to 80k examination, not only increased the reliability of the motor, but also improved the service life.
1.4, This series motors can be rated under the following environmental conditions:
1) The highest ambient air temperature varies with the season, but the type dl (coal mine underground mining face of the motor used) is not more than 35 deg c; dll (factory motor) is not more than 40 deg c; ambient air minimum temperature of -15 c.
2) Altitude not exceeding 1000m.
3) Ambient air relative humidity in coal mine underground mining working face with stubborn non motor does not exceed 95% (when the temperature is 25 degrees centigrade) factory motor does not exceed 90% (when the temperature is 25 degrees centigrade)
4) The motor is used as the dl type in the non mining face in the coal mine, and the maximum surface temperature of the plant is 135 deg c with the explosive gas mixture. Model dllbt4.
5) Motor rated voltage: 380v, 660v, 380/660v three, the power of 3kw and below the motor is 380v.
6) The rated frequency of the motor is 50hz
7) The cooling mode of the motor is IC41 1 (independent fan mounted on the motor shaft).
8) The motor shell protection class is IP55 (dustproof, waterproof motor).
9) The installation type of motor is IMB3; IM B5; IMB35; IMB14; IMB34.
