Xi'an TaiFu Xima Y2 Series Compact High-Voltage Asynchronous Motor Product Introduction
I. Product Model Description
Taking the YKK3551-4 motor as an example, its model designation is interpreted as follows::
- Series Designation"YKK" represents a cage rotor asynchronous motor for closed-type air-to-air coolers.
- Center height and core length"3551" indicates a frame center height of 355 millimeters, using core length No. 1.
- extremity"4" indicates that the motor has four poles.
II. Product Overview
Y2 Series (Frame Center Height H355-560) 6kV High Voltagethree-phase asynchronous motoris aCompact, enclosed cage rotorGeneral-purpose productsThis series of motors is strictly manufactured in accordance with the technical specifications of JB/T10444 and possessesHigh efficiency, energy-saving, low noise, low vibration, reliable operation, easy installation and maintenanceSignificant advantages。
其Key Technical FeaturesIncluding:
- protection classIP54 or IP55, effectively preventing dust and splashing water ingress, suitable for harsh industrial environments.。
- Cooling methodIC411 (Fully Enclosed Self-Fan Cooled), featuring mature and reliable cooling technology.。
- Insulation systemsFeaturing a reliable Class F insulation structure treated with vacuum pressure impregnation (VPI), the motor undergoes temperature rise testing at Class B standards. This effectively extends the insulation's aging lifespan and ensures long-term operational reliability.。
- work systemContinuous Quota Design Based on Continuous Duty Cycle (S1)。
- Standard Power SupplyRated voltage: 6kV, rated frequency: 50Hz. Custom products with other voltage ratings such as 3kV, 3.3kV, 6.6kV, and 60Hz frequency are also available upon customer request.。
This series of motors has a wide range of applications and can serve as the power source for various general-purpose machinery such as fans, compressors, water pumps, crushers, and cutting machine tools. They are extensively used in coal mines, the machinery industry, power plants, and other industrial and mining enterprises.。
III. Structural Features
The Y2 series motors utilizeHigh-strength cast iron base and end coverThe structure is robust and durable. Vertical and horizontal cooling fins are distributed across the exterior of the base, ensuring excellent heat dissipation performance.。
- StatorFeatures an external pressure-fit structure for easy maintenance. The stator windings undergo specialized insulation fixation and vacuum pressure impregnation, delivering superior electrical performance, mechanical strength, and moisture resistance.。
- rotorEmploying a special one-piece cast aluminum process, the guide rails, end rings, and fan are integrally cast for high operational reliability. Complemented by precise dynamic balancing, this ensures smooth motor operation with minimal vibration and noise.。
- Bearings and Junction BoxesThe bearings are equipped with non-stop oiling and drainage devices. The terminal box features a sealed, compact design with flexible wiring and high protection rating.。
