What are the performance requirements for highly flexible cables?

Linear motor refers to a kind of driving device that utilizes the principle of electromagnetic action to convert electrical energy directly into kinetic energy for linear motion, and it is a kind of electric motor that can realize reciprocating linear motion. Linear motors are derived from rotary motors both in terms of structure and working principle. Traditional CNC machine tools are rotary motor + ball screw motion system, through the motor rotation drive transmission mechanism, the rotary motion into linear motion. Due to the technical characteristics of the rotary motor is limited, has been unable to meet the needs of high-precision machine tools. The linear motor is a kind of transmission device that directly converts electric energy into linear mechanical energy, so it does not need any intermediate conversion mechanism. From the linear motor operating characteristics can be seen in the linear motor drive can provide higher speed and acceleration, as well as reduce mechanical wear, improve machining accuracy and repeatability, because the linear motor is driven by electromagnetic thrust, so the system noise is very small, improving the working environment. It is because of these advantages of the linear drive, so it is very suitable for the dynamic characteristics and accurate positioning requirements of the occasion is very high.

In the high acceleration and high speed linear motor drive, and linear motor connected to the highly flexible cable will also follow the motor to do high acceleration, high speed and long distance reciprocating motion, which requires the drag chain cable to withstand greater mechanical stress, flexible cable some bad quality drag chain cable easily because it can not withstand the mechanical stress of high-speed movement, making the outer sheath in the movement of the acceleration process is elongated and then decelerated during the movement of the rebound During the process of deceleration, the outer sheath will be elongated during the acceleration and then rebound, which will make the outer sheath and conductor core produce large friction, resulting in serious wear and tear of the drag chain cables, core short-circuiting, insulation/sheath cracking and other abnormalities, thus affecting the normal work of machinery and equipment. Therefore, in the linear motor drive system used in the performance of highly flexible cables can withstand strong mechanical stress, followed by the need for drag chain cables with high flexibility, bending resistance, wear-resistant and other characteristics. Cable flexible cable professional manufacturers, wire harness manufacturers, new energy original automotive wire, terminal harness processing, specializing in the production of special high flexibility cable, drag chain cable and so on.
