嵌入式力矩电机的设计方法研究

Design Approach and Examination of Embedded Torque Motor

介绍一种用于机床直驱部件的嵌入式力矩电机的设计和电磁结构优化方法。为了使嵌入式力矩电机满足机床内部结构紧凑的要求,必须具有较高的磁密。通过计算分析,得到不同长径比、不同磁极对数、不同槽极比与力矩的关系曲线,然后提出适合于机床部件嵌入式力矩电机的力矩设计经验参考公式。通过有限元软件对电机模型的分析和对样机输出力矩的测试,验证了设计的合理性。

This paper introduces a method for designing of the embedded torque motor as a direct drive assembly for machine tools and for optimization of the electromagnetic structure. In order to let the embedded torque motor satisfy compact structure in the machine higher flux density should be presented. Through computational analysis it is available to obtain varied length-diameter ratio, various numbers of pole pairs, different slot-to-pole ratio and torque curve relationship and set forth the reference formulas for empirical design of embedded torque motor that is adaptive to the machine assemblies. By analyses of the motor model with finite element software and test of the output torque of the prototype, the rationality of the design has been verified.
