Description

Technical Field

The flexible servo motor cable is provided with a flexible buffer inner liner as a filling structure between the cable sheath and the cable core mechanism, and a flexible buffer energy absorption channel hole and a flexible bending deformation outer ring groove are respectively provided inside and on the surface of the flexible buffer inner liner. When the entire cable line encounters bending, it can collapse and absorb energy through the flexible buffer energy absorption channel hole, and through the folding of the flexible bending deformation outer ring groove, it can realize the process of deformation to adapt to the bending condition, thereby achieving the effect of facilitating the response to bending conditions with a large number and intensity, and achieving the effect of improving the overall fatigue resistance of the cable.

[0004] However, the existing servo power cables have poor anti-shielding performance when in use, and are not convenient for shielding external signals and the electromagnetic generated by adjacent cores inside the cable. In the servo motor system, due to the large torque required for rapid start and stop, a high-power transmission power supply is often required to provide support. High-power current transmission will also generate large electromagnetic effects. Mutual interference between electromagnetics will directly affect the normal operation of the power cable signal transmission operation. Utility Model Content
