Common Application Challenges
High-voltage variable frequency motors in heavy industry face predictable operating problems. The table below shows where the YPKK series is designed to help.
Challenge | YPKK Design Feature |
High vibration affecting connected equipment | Low-vibration construction with precision dynamic balancing |
Noise levels in enclosed facilities | Low-noise motor design for indoor plant environments |
Bearing failures under variable load | Replaceable SKF, NSK, or FAG bearings, selectable per application |
Voltage mismatch with existing infrastructure | Six rated voltage options: 3000 V, 3300 V, 6000 V, 6600 V, 10000 V, 11000 V |
Maintenance difficulty at remote sites | Disassembly structure suited for on-site servicing |
Overvoltage risk leading to magnetic saturation | ±5% tolerance built into each rated voltage option |
When supply voltage exceeds rated parameters, it disrupts magnetic flux and increases current draw. The ±5% tolerance range is intended to accommodate real-world supply variation at each rated level.
Technical Features
The YPKK series is designed for variable frequency drive (VFD) operation, which places higher thermal and electrical stress on insulation than fixed-frequency use.
Key specifications:
· Power range: 200 kW to 6300 kW
· Voltage options: 3000 V, 3300 V, 6000 V, 6600 V, 10000 V, 11000 V (each ±5%)
· Standards: JB/T12730 and JB/T12729
· Insulation: Reinforced insulation system evaluated for VFD environments
· Bearing options: SKF, NSK, or FAG — selectable based on load and operating conditions
· Cooling: Forced ventilation for thermal management under variable load

Production Process
Each unit follows a structured production sequence to maintain dimensional accuracy and electrical performance.
1. Raw material inspection — Core laminations, copper windings, and bearing housings are checked before entering production.
2. Winding and insulation — Coils are wound to specification and treated with insulation systems rated for VFD environments.
3. Assembly — Rotors and stators are assembled with precision tolerances to minimize air gap variation.
4. Bearing installation — Bearings from approved brands are installed and lubricated to load specifications.
5. Testing — Each unit undergoes electrical and mechanical performance testing before leaving the factory.
6. SAP system tracking — Production scheduling and quality records are maintained through the SAP platform.
Industry Applications
The YPKK series high voltage frequency asynchronous motor is used across heavy and process industries where variable speed control at high power is required.
· Fans — Mine ventilation, industrial HVAC, and power plant induced draft fans
· Water pumps — Municipal water supply, irrigation, and industrial cooling loops
· Compressors — Air separation, natural gas transmission, and refrigeration systems
