YB2 Ranges of Three-Phase Induction Motors, Buy Marine Electric Motor from China Manufacturer

YB2 ranges of three-phase induction motors are flameproof motors obtained by renewal and generation-changing of YB ranges of 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.

Ambient air temperature changes with season, but does not exceed 35℃ (underground coal mine) or 40℃ (the factory ), and is not lower than -15℃ .

Altitude above sea level: up to 1000m.

Note: when ambient air temperature and altitude are different from the above, refer to GB755.In the moistest month, the monthly-average maximums relative humidity is 90%, and the minimum temperature does not exceed 25℃ in this month (in the factory). In the underground coal mine, the highest relative humidity does not exceed 95%.

In the underground coal mine (non-excavating working) or the factory have easy-ignition and explosive gas , steam and air mixtures , which temperature class T1~T4.

Rated frequency: 50Hz.

Rated voltage: 380V, 660V and 380/660V.

Note: If you have special requirements for frequency, voltage, ambient air temperature and altitude, etc. Please put forward them when ordering.

The type designation consists of several letters and digits.

Three basic mounting arrangements and nine variant mounting arrangements, See the following table:
