Research On Poly-magnet Line-start Permanent Synchronous Motor With Disk-shaped Mangnet

Line-start permanent magnet synchronous motor has a small, line-starting, highefficiency, energy saving significant. In general, line-starting permanent magnetsynchronous motor magnets are embedded in the motor rotor. After a rotor diameter sizeand design space reserved starter cage has been designed, the magnet will be limited to thespecific space. In order to solve the contradiction between the existing line-start permanentmagnet synchronous motor starting performance and power index compete for the limitedspace of the rotor. This paper presents the new structure of poly-magnet line-startpermanent synchronous motor with disk-shaped magnetAt first, this paper introduces the new structure of poly-magnet line-start permanentsynchronous motor with disk-shaped magnet. This kind of poly magnet rotor structure inthe rotor yoke department Settings have gathered magnet by magnetic yoke and permanentmagnet ring and composition. Yoke cylindrical on interval setting guide magnetic pass tothe pole shoe. After starting winding the rest of the limited rotor, the part space can achievehigher air gap magnetic tight.Secondly,Using Ansoft software analysis to permanentmagnet piece of different quantity, thickness and width of different pole shoe when motorair gap magnetic close. Summarizes the assembled magnetic rotor structure design rule andgiven the rotor structure design scheme. Finally, the motor of3d simulation model hasbeen established. Through the finite element software analysis of electromagnetic field, thegather magnet line-starting permanent magnet synchronous motor3d magnetic field hasbeen calculated and analyzed. And contrast to other common built-in structure ofpermanent magnet synchronous motor line-starting simulation. In addition. Also separatelyto starting cage for casting aluminum and copper casting when the motor startingperformance simulation has analysed.Validation in ensure better since the starting abilitypremise to improve motor force to the purpose of the indicators. The results of the studyshow that the new structure of poly-magnet line-start permanent synchronous motor withdisk-shaped magnet solve the existing line-starting permanent magnet synchronous motorstarting performance and force between index for the contradiction of space.
