Description
Technical field
The technology of the present invention relates generally to a kind of magnetic force governor, especially a kind of magnetic force governor for variable speed,
Belong to technical field of magnetic transmission.
Background technique
Magnetic drives are combined forever using existing permanent-magnet material with theoretical based on modern magnetic force theory of magnetism
The magneticaction of magnetic material, to realize a kind of emerging technology of the contactless transmitting of power and torque.
This technology was just suggested early in the 1930s, and is developed by decades, until 70 years 20th century
Generation, due to the transition of social economy, by the development of industrial resources type before to poly-talented transformation, while caused by environmental degradation
Change, the environmental consciousness of common people is gradually increased, people recognize the importance of the theoretical research of permanent magnetism once more.Especially
The appearance of this permanent-magnet material of NdFeB rare earth, the application value on permanent magnetic material performance achieves significant raising, so that permanent magnetism
Theoretical research achieves biggish development.The development of the current explosion type of permanent-magnet drive theory, so that permanent magnet transmission technology
Wide application value is achieved in every field.Nowadays be gradually born based on the technology many advanced magnetic force
Scientific new technology.
U.S.'s Magna Drive magnetic force adjusts the speed progress of the actuation techniques in making a breakthrough property in 1999, the driving method one
The problems such as lifting the axle center centering solved in rotary load system, soft start, vibration damping, speed regulation and overload protection, and make magnetic force
The transmission efficiency of driving is greatly improved, and can reach 98.5%.The technology obtains in every profession and trade at present
It is widely applied, and brings brand-new concept to traditional drive technology, cause a new revolution in transmission field.
USN is by the verifying more than 2 years, and in March, 2004, which has successfully passed the most stringent of 9-G antidetonation of USN
Test, USN realize volume procurement to the technical products.
