Vertical Axis Mounting PMG 1KW-2KW


Vertical-axis permanent magnet generators 1KW-2KW 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:


structural characteristics


  1. Simplified design: adopting a vertical axis layout, with core components including rotor, stator, and tail end bearing, resulting in lower manufacturing and maintenance costs. ?
  2. Space adaptability: Suitable for installation in limited spaces, especially in urban or remote areas. ?


performance advantage


  • Low speed and high efficiency: By reasonable magnetic energy distribution and electromagnetic wiring, high power generation efficiency can be maintained at low speeds, reducing mechanical losses. ?
  • Wind direction adaptability: insensitive to changes in wind direction, suitable for stable operation in multi wind environments. ?


Technical Features


  • Permanent magnet direct drive: No external excitation required, reducing energy loss and improving overall efficiency. ?
  • Low noise and vibration: The simple structure results in less mechanical and electromagnetic noise, and smoother operation. ?
  • ?


Other potential applications


  • Urban Commercial Districts: Can serve as supplementary energy sources for building rooftops or public facilities.
  • Industrial Scenario: Suitable for industrial environments sensitive to space or requiring low maintenance.
