The Design Of Permanent Magnet Synchronous Motor For Elevator

In the 21century ,science and technology develop fast .High technology emerge endlessly and the resource reduce day by day, thus people become more aware of economizing electricity, and protecting our environment , which make the tradition electrical excitation confront great challenge, as well as be supplied with good chance. Compared to the traditional electrical excitation generator ,the permanent magnet synchronize generator has the advantage of high efficiency, high factor, small size, less material, less weight, that can't be replaced. Thus, recently, as the permanent magnet material become more economy, as well as the power electron technology develop, the development of the PMSM is being concerned by all sides.For the complex fabric and interleaved medium boundary, the PMSM design become rather complex ,hard for accurate account, besides, some special problems as magnetic pole fabric dimension optimize, part of magnetic pole lose magnetism are difficulty for design.This article focus on studying PMSM magnetism design, by mastering the fabric and the magnetism loop. Such as analyze the magnetism loop character and process theory of the PMSM .penetrate into discussing PMSM steady capability , influence factor and account ways, analyze PMSM tooth slot torque fabric and restrain method, and also the design process of PMSM and how to improve PMSM design.Focus on studying the character and technique of PMSM design, prepare the course of magnetism design, lucubrating at how to improve the performance of PMSM. This subject study on an example used in elevator drag, adopt finitude data analyze to analyze the PMSM, choose the parameter, make practical scheme for fabric design, Which has been used in project production, proved successfully by model test, match test, and so on.This subject summarizes the design and manufacture of the PMSM , bring a whole of design process and means. Which has also achieve the engineering require by contrast test. The design analyze, manufacture has achieve the previous study aim through the test.This subject also work at magnetism fabric technology, insulate fabric and yawp analyze, which provide helpful consult for the same kind of PMSM design.
