【摘要】：隨著永磁力矩電機(jī)的廣泛應(yīng)用和機(jī)床產(chǎn)業(yè)對(duì)機(jī)電設(shè)備性能要求的提高,其在市場(chǎng)上競(jìng)爭(zhēng)的一個(gè)重要影響因素是永磁力矩電機(jī)的轉(zhuǎn)矩性能。而直接驅(qū)動(dòng)系統(tǒng)的廣泛應(yīng)用,使電機(jī)中的波動(dòng)都會(huì)沒(méi)有緩沖的直接施加在加工平臺(tái)上,導(dǎo)致加工工件無(wú)法滿足平滑度要求。因此,在降低電機(jī)的齒槽轉(zhuǎn)矩的基礎(chǔ)上提高轉(zhuǎn)矩性能是機(jī)床擺頭永磁力矩電機(jī)的一個(gè)重要研究方向,本課題的目的是在保證電機(jī)較高的輸出轉(zhuǎn)矩以及較小的轉(zhuǎn)矩脈動(dòng)的基礎(chǔ)上有效降低A軸電機(jī)的齒槽轉(zhuǎn)矩,本文針對(duì)于雙擺頭A軸永磁力矩電機(jī)主要對(duì)以下內(nèi)容進(jìn)行研究:首先,介紹雙擺頭A軸電機(jī)的結(jié)構(gòu)、特點(diǎn)與原理并介紹其優(yōu)越性。確定雙擺頭A軸永磁力矩電機(jī)的基本電磁方案、定子槽型、轉(zhuǎn)子磁路結(jié)構(gòu)以及永磁體參數(shù)。利用有限元法對(duì)樣機(jī)進(jìn)行電磁場(chǎng)仿真計(jì)算,驗(yàn)證所設(shè)計(jì)電磁方案的合理性,對(duì)樣機(jī)的性能進(jìn)行分析與研究。其次,基于電磁場(chǎng)原理分析了齒槽轉(zhuǎn)矩的產(chǎn)生機(jī)理與其主要影響因素,并從永磁體厚度選擇、極弧系數(shù)選擇、槽口寬度選擇、斜槽等幾種常規(guī)電機(jī)設(shè)計(jì)參數(shù)對(duì)齒槽轉(zhuǎn)矩的影響進(jìn)行進(jìn)一步分析,通過(guò)有限元仿真結(jié)果驗(yàn)證方法的有效性。以上文的驗(yàn)證為基礎(chǔ),從永磁體厚度、槽口寬度和極弧系數(shù)三個(gè)方面的進(jìn)行效結(jié)合,從而對(duì)A軸永磁力矩電機(jī)齒槽轉(zhuǎn)矩的削弱進(jìn)行綜合性優(yōu)化設(shè)計(jì)與仿真分析。通過(guò)分析得出結(jié)論:將永磁體厚度、電樞槽口寬度與極弧系數(shù)進(jìn)行有效綜合優(yōu)化可以降低A軸力矩電機(jī)的齒槽轉(zhuǎn)矩,并提高電機(jī)的輸出轉(zhuǎn)矩。最后,針對(duì)于定子齒頂開(kāi)輔助虛槽法與輔助槽中心線偏移法的有效結(jié)合對(duì)電機(jī)的轉(zhuǎn)矩性能進(jìn)行優(yōu)化與仿真研究。將輔助槽型、槽深、槽個(gè)數(shù)以及槽中心線偏移四種方法進(jìn)行綜合應(yīng)用并對(duì)雙擺頭A軸電機(jī)的轉(zhuǎn)矩性能進(jìn)行優(yōu)化,將四者進(jìn)行有效結(jié)合。同時(shí)以此為基礎(chǔ)分析了電機(jī)的氣隙磁密、反電勢(shì)等其他相關(guān)性能,對(duì)電機(jī)的轉(zhuǎn)矩性能進(jìn)行全面的仿真研究。通過(guò)分析得出結(jié)論:對(duì)于文中的雙擺頭A軸永磁力矩電機(jī)進(jìn)行定子齒頂部開(kāi)輔助虛槽結(jié)構(gòu),同時(shí)合理的結(jié)合槽型、槽深、槽寬、槽個(gè)數(shù)以及槽中心線偏移度會(huì)在保證輸出轉(zhuǎn)矩的前提下有效削弱電機(jī)的齒槽轉(zhuǎn)矩,提高轉(zhuǎn)矩的輸出性能與平穩(wěn)性。
[Abstract]:With the wide application of permanent magnet torque motor (PMSM) and the improvement of mechanical and electrical equipment performance requirements in machine tool industry, the torque performance of PMSM is an important factor affecting the market competition. With the wide application of direct drive system, the fluctuation in the motor will not be directly applied to the machining platform, resulting in the workpiece can not meet the smoothness requirement. Therefore, improving the torque performance on the basis of reducing the torque of the motor is an important research direction of the machine tool swing head permanent magnet torque motor. The purpose of this paper is to reduce the tooth slot torque of A axis motor effectively on the basis of ensuring higher output torque and smaller torque ripple of motor. This paper mainly studies the following contents for double pendulum head A shaft permanent magnet torque motor: first of all, This paper introduces the structure, characteristics and principle of A axis motor with double pendulum head and its superiority. The basic electromagnetic scheme, stator slot type, rotor magnetic circuit structure and permanent magnet parameters of A axis permanent magnet torque motor with double pendulum head are determined. The finite element method is used to simulate the electromagnetic field of the prototype, and the rationality of the designed electromagnetic scheme is verified. The performance of the prototype is analyzed and studied. Secondly, based on the principle of electromagnetic field, the generation mechanism of tooth groove torque and its main influencing factors are analyzed, and the selection of the thickness of permanent magnet, the selection of polar arc coefficient and the selection of slot width are given. The influence of several conventional motor design parameters on the torque of the gear slot is further analyzed and the effectiveness of the method is verified by the finite element simulation results. On the basis of the above verification, this paper combines the thickness of permanent magnet, the width of slot and the coefficient of polar arc, and makes a comprehensive optimization design and simulation analysis on the weakening of tooth torque of A-axis permanent magnet torque motor. It is concluded that the effective optimization of the thickness of permanent magnet, the width of armature slot and the coefficient of polar arc can reduce the tooth groove torque of A axis torque motor and increase the output torque of the motor. Finally, the torque performance of the motor is optimized and simulated based on the effective combination of the stator tooth top open auxiliary virtual slot method and the auxiliary slot centerline offset method. The auxiliary groove type, groove depth, slot number and groove centerline offset are comprehensively applied to optimize the torque performance of double pendulum head A axis motor, and the four are effectively combined. At the same time, based on the analysis of the air gap magnetic density, reverse EMF and other related performance of the motor, the torque performance of the motor is studied comprehensively. It is concluded that the double pendulum A-axis permanent magnet torque motor is constructed with auxiliary virtual slot at the top of the stator tooth, and the groove type, groove depth and slot width are reasonably combined. The number of grooves and the offset of the centerline of the grooves can effectively weaken the torque of the motor and improve the output performance and stability of the motor on the premise of ensuring the output torque.
