Description
Technical field
The utility model relates to a kind of wind-driven generator, specifically is a kind of magnetic suspension gentle breeze-driven generator.
Background technology
The bearing that existing wind-driven generator adopts is the ball bearing of contact, and friction problem is inevitable.Frictional force is loss of energy and parts not only, also produce heat, and parts are out of shape because of temperature rise, influence precision, even destroy entire equipment.Speed is higher, and problem is more serious, cooperates suitable lubricating to reduce coefficient of friction usually.Yet lubricated meeting produces pollution problem, is unfavorable for environmental protection.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of making does not have the magnetic suspension of Mechanical Contact gentle breeze-driven generator between rotor and the stator, to avoid mechanical wear, to reduce the function that starts wind speed, can realize breeze wind.
For solving the problems of the technologies described above, the utility model provides a kind of magnetic suspension gentle breeze-driven generator, and it comprises: magnetic suspension system, and this magnetic suspension system comprises: controller, power amplifier, electromagnet, rotor and transducer; The axle core of rotor is parallel with the magnetic flotation line that electromagnet produces, the transducer that is used to feed back the positional information of rotor links to each other with the rotor position information input of controller, and the rotor-position control output end of controller links to each other with coil power end on the electromagnet through power amplifier.
Further, described rotor is located on the main shaft, and main shaft is located on a pair of radial magnetic bearing, and electromagnet has a pair of and is located at the rotor both sides respectively; The front end of main shaft is provided with fan blade.
Good effect of the present utility model: (1) is applied to magnetic levitation technology in traditional gentle breeze-driven generator rotor-support-foundation system, with magnetic bearing replacement mechanical bearing in the past, not only can significantly reduce the frictional force that rotor and bearing are asked, moment of friction, realize " the light breeze starting; breeze wind " of gentle breeze-driven generator, enlarge the utilance of wind resource, improve generating efficiency, can also exempt the high cost of bearing operation and maintenance in the past, reduce cost of wind power generation, this not only helps the development of popularizing of China's wind power generation and wind-powered electricity generation cause, and China's enforcement energy-saving and emission-reduction work is played important impetus.(2) magnetic bearing of Cai Yonging has many advantages: at first, it does not almost have any rotational resistance, and the rotating speed of rotor can be far above other bearing; The second, do not need complicated lubricating system or baric systerm, can save the space; The 3rd, life cycle is long, and maintenance cost is low; The 4th, can avoid the noise that is produced because of friction; The 5th, applicable to particular job environment such as low temperature or high vacuum states, as the outer space; The 6th, can see through active control required rigidity is provided, and effectively suppress the vibration problem that produces because of running up.(3) magnetic suspending wind turbine generator adopts the manufacturing of magnetic pull principle design.Because magnetic pull is bigger 500 times than magnetic repulsion, thereby reduced the volume of windmill effectively, and the cancellation axial thrust bearing, the blower fan cost reduced; Reduce mechanical friction resistance, raise the efficiency; Eliminate mechanical abrasion, reduce noise, improve reliability and fan life.Substitute traditional bearing with novel magnetically levitated bearing; Replace traditional horizontal axis rotor and conventional vertical axis rotor with the small-sized wind wheel of novel Φ type vertical axis; Replace traditional teeth groove structure with novel slotless configuration.(4) magnetic suspension bearing does not have friction, no wearing and tearing, noiselessness, unlubricated oil, highly sensitive type, and can be at a high speed, thereby rotating machinery volumes such as motor, pump greatly can be reduced, and its life-span is long, vibration is little, and advantage is a lot.It almost is that non-loaded axle core is shored toward anti-magnetic flotation line direction that the characteristics of magnetic suspension bearing are with profit, and it is unsettled to form whole rotor, on fixing running track.
