Abstract

Permanent magnet synchronous motors (PMSM) are very popular in the industrial market. Recently, robots are installed to compensate for the shortage of labor. Due to the increase in motors, the number of power lines and position sensor cable wiring are increased; this increase in complicated wiring is a problem. As a method to solve these problems, power superimposition technology in the power line of a PMSM is expected to reduce the distribution cables. In this paper, the power superposition technology method, and circuit equations of mounting transformers in power lines are presented and are then verified by experiment, simulation, and linear analysis. The circuit equation is proposed as a three-phase circuit equation, which is transformed into a dq-circuit equation by a transformation matrix. The characteristics of the electric angular frequency versus the dq-axis voltage demonstrated satisfactory results, with errors within 1% in linear analysis and simulation. The linear analysis and experiment are shown to be similar, although there are some errors. The validity of the circuit equations could be demonstrated by the verification results.

在 PMSM 电源线上使用单相变压器的位置传感器功率叠加电路方程

永磁同步电机（PMSM）在工业市场上非常流行。最近，机器人的安装弥补了劳动力的不足。由于电机数量的增加，电源线和位置传感器电缆布线的数量也随之增加；复杂布线的增加是一个问题。作为解决这些问题的一种方法，PMSM 电源线中的功率叠加技术有望减少配电电缆。本文提出了功率叠加技术方法以及在电力线中安装变压器的电路方程，并通过实验、仿真和线性分析进行了验证。提出的电路方程为三相电路方程，通过变换矩阵将其转换为 dq 电路方程。电角频率与 dq 轴电压的特性显示了令人满意的结果，线性分析和模拟的误差均在 1%以内。虽然存在一些误差，但线性分析和实验结果相似。验证结果证明了电路方程的有效性。
