Abstract: High linearity was required to submersible motor’s stator,and this paper developed a suit of non-contact detection device about linearity.It was introduced to the methods of data receiving and disposal in brief,and it was placed emphasis on specifying the structure of device,inspecting step and principium,identification of stator’s non-gap position.The device looked for the position of adjusting linearity rapidly and exactly,and the process of adjusting linearity could be observed real time,meanwhile,the device also possesses features of high accuracy,high stability,convenient operation,etc.
Key Words: Submersible motor;Adjust linearity;Eddy current sensor;USB-CAN communication
