Magnetic wind power suspension generator

Can a wind generator be suspended on a permanent magnet?

Using the effects of magnetic suspension, wind generator will be suspended on permanent magnets (PMs) as a replacement for ball bearings, which are normally used on conventional wind turbines. The features of this system are effective for saving energy, avoiding heat generation and preventing mechanical contact.

Why is magnetic suspension important for wind turbines?

The magnetic suspension not only reduces the cost of the bearings and their maintenance, but also reduces the downtime of the wind turbine and therefore, improves the over-all efficiency of the system. Magnetic suspension technology applied to wind turbine is an emerging technology; the development of maglev magnetic wind turbine is just beginning.

Does magnetic suspension reduce wind speed?

Recently, magnetic suspension technology has been applied to the vertical axis wind turbine, in which the entire rotor weight of a VAWT was suspended by magnetic bearing. The turbine friction was greatly reduced, and start-up wind speed decreased. Figure 7 shows the magnetically suspended and self-pitched VAWT for street lighting.

How a magnetically suspended wind turbine works?

The blade pitch is adjusted naturally during rotation for the best windward angle. As a result the blades always produce the maximum thrust wind force improving the wind turbine efficiency. Thus, the magnetically suspended and self-pitched vertical-axis wind turbine will be designed with uncomplicated structure, high efficiency and low cost. 2.

Can a vertical axis wind turbine be suspended?

Abstract— This paper presents a novel design of a vertical axis wind turbine (VAWT) for power generation purposes. Using the effects of magnetic suspension, wind generator will be suspended on permanent magnets (PMs) as a replacement for ball bearings, which are normally used on conventional wind turbines.

Can magnetic bearings support wind turbine rotor weight?

Specifically, the entire wind turbine rotor weight can be supported by magnetic bearings. The friction of the bearings is essentially non-existence. There is no need for bearing lubrication, and the maintenance cost can be reduced. Furthermore, the magnetic suspension technology can eliminate mechanical vibration and reduce noise.
