Product Overview – Professional Design with Multiple Advantages
Technical Standards and Structural Features
O YKK Series (H355–1000) 6 kV / 10 kV high-voltage three-phase asynchronous motors are totally enclosed squirrel-cage motors equipped with air-to-air coolers.
Protection class: IP44 or IP54
Cooling method: IC611 (in accordance with GB/T 1993)
Key advantages include:
- High efficiency and energy saving: Optimized electromagnetic design and airflow system reduce losses and improve operating efficiency
- Low noise and low vibration: Precision machining and dynamic balancing ensure smooth and quiet operation
- Compact structure: Reduced size and weight, saving installation space
- Easy maintenance: Rational design simplifies installation, inspection, and servicing
Wide Application Range
YKK series motors are ideal drive sources for various industrial equipment, including:
- Fans, compressors, and pumps
- Crushers and metal cutting machine tools
- Fixed equipment in coal mines, power plants, and industrial enterprises
With strong environmental adaptability, these motors operate reliably under complex and demanding working conditions.
Technical Features – Advanced Design and Reliable Performance
Box-Type Structural Design
The YKK series adopts a fully welded steel plate box-type frame and end covers with a detachable internal structure.
Protective covers and inspection panels are installed on the sides and top of the motor, allowing easy access to internal components for maintenance and repair.
This structure provides light weight, high rigidity, and excellent practicality.
High-Quality Insulation System
- Stator with slide-in external press-fit structure
- Stator windings use F-class low-resin insulation materials
- End windings are securely fixed and tied
- Treated with vacuum pressure impregnation (VPI) solvent-free varnish
This ensures excellent insulation performance, strong mechanical strength, and superior moisture resistance.
Motors rated above 6000 V are equipped with anti-corona protection measures.
Flexible Bearing Configuration
Bearings are available in rolling bearing or sleeve bearing designs, depending on motor power and speed.
Standard bearing protection class matches the motor enclosure (IP44 or IP54), with higher protection levels available when required.
Efficient Cooling System
A top-mounted enclosed air-to-air cooler provides excellent heat dissipation.
Cooling method IC611 ensures stable motor operation even in high-temperature environments.
