YB3 Series Three-Phase Flame-Proof Induction Motors, Buy Marine Electric Motor from China Manufacturer

YB3 ranges of three-phase induction motors are flameproof motors obtained by renewal and generation-changing of YB2 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 temperature : -15℃ ~35℃ (underground coal mine) or -15℃ ~40℃ (the factory ).

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 when ordering.

The type designation consists of several letters and digits.
