The stability of magnetic bearings will seriously affect the overall operation of the motor. Magnetic bearing temperature is closely related to the performance of magnetic bearing (MB) system. Therefore, loss calculation and thermal estimation are very important in the design of MB system. A MB system including a pure radial magnetic bearing (RMB) and a combined radial and axial magnetic bearing (CRAMB)...
In this paper, an asymmetric permagnet biased axial magnetic bearing has developed. The PM rings can not only produce bias flux, but also provide a large axial force to reduce the burden of axial bearing. As a result, the proposed PBAMB can lower the current, lower the power loss and make an easier control. Firstly, structure and operation principle are introduced. Then, the mathematical models are...
With the development of Internet technology, locating and identifying the page needed quickly from a sea of pages has become one of the most pressing and important demand. For the sake of acquiring video pages from mass web pages and analyzing their principal characteristics, this paper proposes the technology, which combines the form and content feature of the video page with topic web crawler of...
Due to the trend of diversification of media in social network, the deep learning of multimedia data is becoming more and more important. This paper analyzes the special tag information of image, audio and video data on the internet, and proposes an effective recognition method of multimedia data for social network. The method will provide a lot of data for the multimedia content analysis of social...
Today, the cross-cultural, cross-regional, cross-age, multi-disciplinary international cultural integration makes design art more diversified and pluralized, which puts forward higher and new requirements for the education of artistic design. Integration and acquisition have been new trends of Taiwan's artistic design education in recent years. This paper analyzes and compares these new trends on...
In order to solve the inefficacious problems of traditional Bowring formula when the longitude crosses line plusmn180deg and the latitude crosses the plusmn90deg line, an improved algorithm for the solution of geodetic problems is proposed in this paper. By introducing error compensation, the dispersion of the longitudes or the latitudes is considered to deal with the borderline mutation. Simulation...
Creative industry has become a necessary choice when social economy develops to a certain phase. It represents the future trend of newly-rising industries with knowledge economy, consumption culture and innovation theory as background. China??s creative industries, though still in the preparation phase and starting late, but with a higher start and faster movement, have become new growing hot spots...
