Explosion-proof three-phase asynchronous motor YBBP280S-2GW-75KW-380V-IC416

Using "d" explosion-proof design, the base frame is made of Q345B fully welded steel plate, ensuring high rigidity and impact resistance. It can withstand an explosion pressure of 1.0 MPa, with explosion protection class Ex db IIC T4 Gb. Explosion-proof surfaces are precision machined with controlled clearances in combination with high temperature O-rings. This isolates the motor from hazardous internal/external environments, preventing the risk of electrical spark leakage, and is suitable for high-end flammable/explosive scenarios.

As a three-phase variable-frequency asynchronous motor, it features optimized stator and rotor slot matching. The rotor uses rare earth aluminum alloy conductors, which increases conductivity by 8% to meet the wide frequency range requirements of variable frequency drives. The stator windings are made of ultra-thin 0.35mm thick high permeability silicon steel sheets treated with VPI vacuum impregnation. Class F insulation withstands 1.2 times the rated voltage surge and has a service life of 20 000 hours, effectively resisting the corrosive effects of high-frequency harmonics generated by frequency conversion.

The IC416 forced ventilation cooling system is used with an independent axial fan and interleaved fin heat exchanger, which increases the heat dissipation area by 25%. Temperature rise is reduced by 12 degrees compared to similar products, ensuring compliance across the entire speed range of 5-100 Hz. Equipped with an explosion-proof terminal box designated "EX", its sealed latching design allows separation of main and auxiliary power circuits. The wiring compartment offers ample working space with an IP55 rating for easy maintenance.

The base has a standardized support structure whose dimensions comply with IEC standards, ensuring high compatibility with YB3 series motors. It directly replaces legacy explosion-proof motors without the need to modify the mounting base. Roller bearings are used in combination with labyrinth seals and continuous lubrication systems to prevent the ingress of dust and moisture. Bearing life has been extended to 30 000 hours, with maintenance intervals up to one year.

Explosion protection level: Ex db IIC T4 Gb. Suitable for hazardous zones 1 and 2, compatible with explosive gas atmospheres of classes IIA, IIB and IIC (e.g. methane, propane, coal gas). Temperature class T4 provides surface temperatures of<=135 degree, which ensures a low failure rate even in difficult conditions with gas concentrations of<=1%. Provides reliable security when performing high-risk operations.

Supports stepless speed control from 5 to 100 Hz with constant torque at 5-50 Hz and constant power at 50-100 Hz. The starting torque reaches 2.5- times the rated torque, which allows you to easily drive loads with a high moment of inertia. The starting current is regulated within 1.5 times the rated current, which reduces the network load by 60% compared to traditional motors. Combined with a variable frequency drive, it provides high-precision speed control and smooth starting, which greatly minimizes losses when starting and stopping equipment.

Class F insulation combined with Class B temperature rise testing provides sufficient thermal margin to ensure long-term stable operation in ambient conditions ranging from -15℃to 40℃and at altitudes of less than or equal to 1300 m. Precision machining ensures low vibration and noise levels, meeting industrial quiet requirements. The optimized electromagnetic design, meeting IE4 energy efficiency standards, reduces iron and copper losses, delivering 15% lower power consumption than traditional explosion-proof motors and long-term energy cost savings.

Compatible with low voltage specifications including 380V and 660V, with the ability to configure special voltages and 60Hz versions. The power rating covers standard frame sizes, making it suitable for a variety of industries such as petrochemicals, mining and metallurgy. Ability to drive compressors, pumps and other equipment. Additional sensors provide intelligent monitoring and predictive maintenance, reducing downtime by 30%.
