Vertical Axis Mounting PMG 3KW-30KW
Vertical-axis permanent magnet generators 3KW-30KW are primarily used for low-wind-speed power generation and distributed energy systems, making them suitable for energy demand scenarios in remote areas such as rural, pastoral, and mountainous regions, as well as urban peripheries.
Advantages of Low-Wind-Speed Power Generation
The vertical-axis permanent magnet generator, designed with permanent magnet bearings and Halbach magnet pole structures, can significantly reduce the starting wind speed (typically lower than traditional horizontal-axis generators), enabling stable power generation in low-wind environments. Its permanent magnet bearings require no lubrication or maintenance, with a friction coefficient approaching zero, markedly enhancing mechanical efficiency and operational reliability. ?
Distributed energy systems
This type of generator is commonly used in distributed wind-solar hybrid power generation systems, suitable for deployment in remote areas such as rural, pastoral, and mountainous regions to meet local electricity demands. With its compact structure and low maintenance costs, it can be integrated with other renewable energy sources like solar power to form a stable microgrid system.
General Features:
The vertical axis permanent magnet generator combines the vertical axis structure with permanent magnet technology, and has the characteristics of simple structure, low speed and high efficiency, and strong adaptability. The following is a specific analysis:
