specific Embodiment approach 3
[0052] Embodiment 3: This embodiment further describes Embodiment 1 or 2. It also includes an isolation transformer 7 , and the isolation transformer 7 is arranged between the output end of the power supply line and the input end of the servo amplifier 5 .
[0053] Isolation transformer 7: When the servo amplifier 5 and the servo motor 6 are working, a large amount of high-frequency electromagnetic interference will be generated. Since the servo system and the detection system are at the same grid point, the high-frequency interference of the servo system may flow back to the power supply and ground wire of the grid, causing interference to the detection equipment. The 380V power supply line is used to supply power to the servo system separately after passing through the three-phase isolation transformer, so that the servo system and the detection system do not have electrical contact, thereby effectively isolating.
