The YB3 series of explosion-proof three-phase induction motors are flame-proof motors that meet advanced international standards. These explosion-proof motors feature high efficiency, high locked-rotor torque, low noise and vibration, and reliable operation. The motor output and mounting comply with IEC standards and GB3836.2 standards for electrical apparatus in explosive situations. the flame-proof feature makes these induction motors ideal for coal mines where methane and coal dust may be present or in factory spaces where flammable gases may be present.

Features:
1. IP55 protection rating.
2. Vertical and horizontal cooling ribs on frame.
3. Ball bearings, small diameter fans, and slot-skewing slopes for low vibration.
4. F class insulation. Above sea level and with standard ambient temperatures, the temperature rise limit of the stator windings is 80K (resistance method). For a frame size of 315L2 and for 4-pole motors with a frame size of 355, the temperature rise limit is 105K.
5. Cable or steel conduit entry. The terminal box has three terminals (for single voltage) or six terminals (for double voltages) and is located on the top of the motor. Armoured cable can also be used.

Ambient Conditions
Ambient temperature: -15℃~35℃ (underground coal mine) or -15℃~40℃ (factory space)
Altitude above sea level: up to 1000m
Note: When ambient air temperature and altitude are different from above, refer to GB755.
In the wettest month, the monthly-average maximum relative humidity is 90%, and the minimum temperature should not exceed 25℃ (within a factory space). In an underground coal mine, the highest relative humidity should not exceed 95%.
If the underground coal mine (non-excavating conditions) or a factory have easy-ignition and explosive gases or steam, the temperature class should be 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 specify them when ordering.
