摘要:The design of a control system of the stator and rotor height difference detection device for air conditioning compressor motor based on PLC control, including hardware system, control system. XTG105 grating micrometer sensor is used to detect the difference between stator and rotor height. MITSUBISHI FX3U PLC controller is adopted as the system control core. The system parameter setting and operation monitoring are carried out through the WEINVIEW TK6070ip color display touch screen to ensure the normal operation of the system. The system controls the height difference detection device to automatically complete the detection, determination, marking and other processes. The working state is stable and the detection precision is high.
