Collecting parameters such as current and temperature on the motor rotor can effectively prevent rotor side faults and achieve motor vector control better. However, the running rotor rotates at high speed, making it very difficult to provide the signal measured on the rotor side to the controller on the stator side. The electric field coupling wireless signal transmission technology consists of two pairs of axially aligned circular parallel plates forming capacitors, which are installed on both sides of the stator and rotor at the end of the motor. High-frequency and low impedance characteristics of the close-range plate capacitors are utilized to transmit digital signals between the motor stator and rotor, with significantly lower signal delay than other wireless communication technologies. Then modeled the communication circuit, calculated the parameters of each component, analyzed the causes of signal distortion, and the design of a contactless high-frequency signal transmission circuit based on parallel plate coupling capacitors was realized. An experimental platform was built, analog signals from the rotor side were collected and transmitted. By comparing the experimental results, the correctness of communication theory was verified.

采集电机转子侧的电流、温度等参数,可以有效预防电机的转子侧故障,更好地实现电机的矢量控制。但运行中的电机转子是高速旋转的,将转子侧测量得到的信号提供给定子侧的控制器十分困难。所提出的电场耦合式无线信号传输技术将2对轴向正对的圆环形平行板构成电容器,分别安装于电机端部的定、转子两侧,并利用近距离极板电容的高频低阻抗特性将数字信号传递于电机定转子间,且信号延迟明显低于其他无线通信技术。进一步对通信电路进行建模,计算各元件的参数,分析信号畸变的原因,实现了基于平行板耦合电容的无接触式高频信号传输电路的设计。搭建实验平台,采集并传输转子侧的模拟量信号,并通过对比实验结果验证了通信理论的正确性。

采集电机转子侧的电流、温度等参数,可以有效预防电机的转子侧故障,更好地实现电机的矢量控制。但运行中的电机转子是高速旋转的,将转子侧测量得到的信号提供给定子侧的控制器十分困难。所提出的电场耦合式无线信号传输技术将2对轴向正对的圆环形平行板构成电容器,分别安装于电机端部的定、转子两侧,并利用近距离极板电容的高频低阻抗特性将数字信号传递于电机定转子间,且信号延迟明显低于其他无线通信技术。进一步对通信电路进行建模,计算各元件的参数,分析信号畸变的原因,实现了基于平行板耦合电容的无接触式高频信号传输电路的设计。搭建实验平台,采集并传输转子侧的模拟量信号,并通过对比实验结果验证了通信理论的正确性。

Collecting parameters such as current and temperature on the motor rotor can effectively prevent rotor side faults and achieve motor vector control better. However, the running rotor rotates at high speed, making it very difficult to provide the signal measured on the rotor side to the controller on the stator side. The electric field coupling wireless signal transmission technology consists of two pairs of axially aligned circular parallel plates forming capacitors, which are installed on both sides of the stator and rotor at the end of the motor. High-frequency and low impedance characteristics of the close-range plate capacitors are utilized to transmit digital signals between the motor stator and rotor, with significantly lower signal delay than other wireless communication technologies. Then modeled the communication circuit, calculated the parameters of each component, analyzed the causes of signal distortion, and the design of a contactless high-frequency signal transmission circuit based on parallel plate coupling capacitors was realized. An experimental platform was built, analog signals from the rotor side were collected and transmitted. By comparing the experimental results, the correctness of communication theory was verified.
