Structural Features of YKK High-Voltage Motors
YKK high-voltage motors feature a box-type structure with a steel plate welded frame, offering lightweight construction and excellent rigidity. These enclosed, air-to-air cooled cage-type asynchronous motors incorporate an air-to-air cooler at the top.
Stator windings utilize F-class heat-resistant insulation material with secure top binding. Vacuum pressure impregnation ensures superior insulation performance and mechanical strength.
The rotor employs a reliable squirrel-cage structure with cast aluminum or copper conductors. Bearings are available in rolling or plain types, selected based on motor speed and power rating.
Applications of YKK High-Voltage Motors
YKK high-voltage motors can drive various general-purpose machinery, including compressors, water pumps, fans, crushers, cutting machine tools, transport machinery, and other mechanical equipment. They serve as prime movers in mining, mechanical industries, power plants, and other industrial and mining enterprises. For applications such as driving blowers, coal mills, rolling mills, or hoists, please specify at the time of ordering.
