YBKS Series High Voltage Flameproof motor

YBKS Series High Voltage Flameproof Motor 

When you're working in a dangerous environment, you need to be dependable without any compromises. From 3 to 10 kV, the YBKS Series High Voltage Flameproof motor from Tellhow Shenyang Electric Machine gives you 185 to 5600 kW of strong power. These motors are made to work in dangerous places and are energy efficient up to GB 30254-2 Level 2. They also have flameproof grades of ExdI Mb, ExdIIAT4 Gb, and ExdIIBT4 Gb. Our 190,000-square-meter factory can make 8 million kW of power, and our small construction ranges from H500 to H800 frame sizes and 2 to 12 pole configurations. This gives you high power density, low vibrations (under 2.3 mm/s), and less noise.

Why Choose Our High Voltage Flameproof Solution?

Uncompromising Explosion Protection

Your safety rules require more than just following them. Our motors have strengthened flameproof casings that keep blasts inside without setting off dangerous gases around them. When you work with methane, ethylene, or flammable dust, the Ex d grade means that every joint surface is carefully machined to stop flames from spreading.

Superior Cooling in Extreme Conditions

Working in oil plants or on ocean platforms? The air-to-air cooling technology keeps the temperature stable without letting any germs get inside. You won't have to worry about humidity, salt spray, or changes in temperature hurting efficiency. Even when the load is on all the time, the design keeps the temperatures of the windings within the limits for the insulation class.

Energy Efficiency That Reduces Operating Costs

Our special magnetic circuit designs and high-efficiency algorithms make your power bills go down because they use 15-20% less energy than regular motors. This saves a lot of money over a 10-year period, which is especially important when running multiple units in mines or chemical processing.

Built for Heavy-Duty Applications

When you need it, these motors give you up to 250% starting power for everything from rotary fans to longwall conveyors. The strong rotor design and improved stator shape reduce harmonic effects, which lowers the extra heat and shaking that are common in variable frequency uses.

Technical Specifications

Where Your Operations Benefit Most

Petrochemical Refineries

You are in charge of places in Zones 1 and 2 that have mixes of dangerous gases. Your oil transfer pumps and big rotary compressors will run safely with our YBKS Series High Voltage Flameproof motor. The sealed container keeps the spark from starting even when there are electricity problems inside, meeting the strict requirements of places with a lot of ethylene and methane.

Underground Coal Mining

In underground activities, air flow is very important. These motors power large fans that keep air moving through longwall systems, which are always at risk of gas and dust buildup. The flameproof design can handle the rough, gritty conditions and keep working reliably shift after shift.

Steel and Metallurgy

Motors for hot rolling mills and blast furnaces need to be able to handle high temperatures and big loads. You get steady power delivery and almost no downtime, which is very important when production delays cost a thousand dollars an hour.

Offshore Oil Platforms

Drilling mud pumps work in salt spray conditions that quickly eat away at regular motors. Our advanced coating systems and protected cooling paths make the service life longer, which means that faraway bases don't have to be shut down for expensive upkeep.

Intelligent Design Features You'll Appreciate

Adaptive Load Management

The motor adapts itself naturally to different loads, reducing energy use while still working at its best without any help from the user. This smart control keeps your operating range efficient and extends the life of your parts.

Multi-Dimensional Monitoring Compatibility

It's easy to connect to devices that track conditions. Real-time tracking of shaking, temperature, and electrical factors lets you do preventive maintenance that stops breakdowns before they happen.

Wide Voltage and Frequency Adaptability

Corona-resistant insulation that has been strengthened is good for uses that use variable frequency drives. The VPI resin treatment can handle high-frequency voltage spikes (dv/dt) that regular motors can't, which keeps the insulation from breaking down too soon.

Maintenance-Friendly Construction

To get to important parts, the whole thing doesn't have to be taken apart. Inspection of bearings, checks of terminals, and regular maintenance can be done quickly, so production is interrupted as little as possible.

Customization to Match Your Exact Needs

No two industrial operations are identical. Our ODM/OEM capabilities let you specify:

• Power and speed configurations tailored to your process requirements
• Insulation class optimization for unique environmental challenges
• Structural modifications for space-constrained installations
• Voltage ratings beyond standard 3 kV, 6 kV, and 10 kV options

Whether you need a single prototype or large-scale production runs, our 500-million-RMB registered capital and comprehensive manufacturing infrastructure support your project from concept to commissioning.

Quality You Can Verify

Every YBKS Series High Voltage Flameproof motor undergoes rigorous testing before shipment:

• Hydrostatic pressure testing at 1.5 times rated conditions
• Partial discharge measurement ensuring insulation longevity under electrical stress
• Vibration analysis per ISO 10816 standards
• Temperature rise verification at full load
• Flameproof joint inspection using precision measurement tools

Our certifications including CE, UL, VDE, CCC, and compliance with IEC 60034 and NEMA MG1 standards give you confidence in regulatory acceptance across global markets.

Frequently Asked Questions

Q: Can these motors operate at reduced speeds with variable frequency drives?

A: Yes. When running below 10% of rated speed, pair the motor with an independent forced-ventilation system (IC416). This ensures adequate cooling when the shaft-mounted fan generates insufficient airflow at low RPMs.

Q: What makes the flameproof protection reliable?

A: The Ex d rating certifies that the enclosure contains internal explosions without external ignition. Precision-machined joint surfaces with specific gap tolerances prevent flame propagation—critical in explosive atmospheres.

Q: How do you handle harmonics from VFD operation?

A: Our optimized rotor and stator geometries minimize harmonic effects that cause additional heating and vibration. The reinforced insulation system with VPI treatment handles electrical stresses from high-frequency switching.

Q: What maintenance focus does the flameproof design require?

A: Protect the flameproof joint surfaces from corrosion and mechanical damage during service. Any scratches or dents compromise explosion-proof integrity. Regular inspection with torque verification of enclosure bolts is essential.

Q: Are replacement parts readily available?

A: Yes. Our global support network maintains spare parts inventory with stable supply chains. Lifecycle maintenance services ensure you get components quickly, minimizing downtime.

Q: Can you customize voltage ratings beyond standard offerings?

A: Absolutely. Special voltage and frequency requirements can be accommodated per customer agreement. Our engineering team works with your specifications to design compliant solutions.
