Product Attributes
Product Description
The YPKK Series High-Voltage Three-Phase Asynchronous Motors (Frame Size H355-1120) feature a rational structure and advanced manufacturing technology. They offer distinct advantages including high efficiency, energy savings, low noise, low vibration, and reliable operation, making them easy to install and maintain.
Standards & Compliance
The motor's power ratings, mounting dimensions, and electrical performance comply with the national standard GB755-2000 ("Rotating Electrical Machines - Rating and Performance") and relevant IEC standards, as well as the industry standard JB/T10314.2-2002.
Operating Environment
Designed for environments where the altitude does not exceed 1,000m above sea level and the ambient air temperature does not exceed 40°C, free from serious dust, corrosive, or explosive gases. Customized versions for hot, humid zones, and plateau areas are available upon request.
Structural Features
-
Frame: Adopts a box-type structure welded from steel plates, ensuring light weight and excellent rigidity.
-
Cooling: A closed air-to-air cooler is mounted on top of the motor, designed for easy dismantling and installation to facilitate maintenance.
-
Stator: Uses an external pressure mounting structure. The stator windings are made of F-class insulating materials with reliable fixing and tying.
-
Insulation Process: The windings undergo multiple turn-to-turn impulse voltage tests and voltage withstand tests. They are treated using advanced German Vacuum Pressure Impregnation (VPI) solvent-free paint equipment, ensuring excellent insulation properties, high mechanical strength, and strong moisture resistance.
-
Rotor: The squirrel-cage rotor utilizes a copper bar structure manufactured via advanced welding technology. It undergoes dynamic balancing verification to ensure smooth and reliable operation.
Bearings & Control
Depending on the power and speed, the motor is equipped with either rolling bearings or sliding bearings. It supports frequency conversion speed control with a range of 5-50 Hz. While the standard rated voltage is 6kV/10kV, we can customize voltage, frequency, and protection levels to meet specific requirements.
