Custom Servo Cable Solutions for Motion Systems
Servo and motor cables play a critical role in modern motion systems because they support power delivery, signal stability, and system accuracy between drives, motors, and control components.
In many applications, servo cables must do more than carry power alone; they also need to support low-voltage feedback transmission, resist electromagnetic interference, and maintain performance under continuous flexing or torsional movement.
At Hulk, we build custom servo & motor cable solutions around the real operating conditions of your equipment. Whether you need a servo power cable for a CNC machine, a feedback cable for precise signal transmission, or a hybrid cable that combines power and signal in one structure, we can tailor the cable design to your mechanical, electrical, and environmental requirements.
Servo & Motor Cable Types We Customize
We support a wide range of custom servo cable designs for industrial motion control systems, helping customers match cable construction to installation method, movement pattern, shielding need, and drive compatibility.
Servo Motor Power Cable
Used to transmit power between the drive and the motor in servo systems and other motion control equipment. These cables are designed for stable current transmission, durability, and long-term operation in machine tools, packaging equipment, and automation lines.
Servo Feedback Cable
Designed to transmit low-voltage feedback signals from the motor back to the drive or controller for position, speed, and motion accuracy. Because feedback performance depends on clean signal transmission, this cable type often requires enhanced insulation and shielding for EMI-sensitive applications.
Encoder Cable
Used in servo and motion systems where encoder signal integrity is essential for monitoring and control. We can customize conductor layout, pair structure, shielding design, and jacket materials based on the motion and environmental demands of your application.
Hybrid Servo Cable
Hybrid servo cables combine power supply and signal transmission in one cable structure, helping simplify installation and reduce cable management complexity in compact equipment designs. This format is often useful where space efficiency, installation speed, and clean routing are important.
Pre-Assembled Servo Cable Assembly
For customers who need ready-to-install solutions, we also support custom servo cable assemblies with specified length, conductor arrangement, and application-based build requirements. This helps reduce installation time and improve consistency in OEM and repeat-order projects.
Built for Demanding Industrial Conditions
Motor and servo cables are often exposed to continuous motion, vibration, EMI, tight bending radius requirements, oils, and other mechanical or environmental stresses, so cable construction must be matched carefully to the working condition.
Shielding & Signal Integrity
Shielding options improve EMI protection and signal integrity in feedback applications, where clean low-voltage transmission is critical for accurate motion control and system reliability.
Conductor Flexibility & Fatigue Resistance
Fine-stranded conductor options enhance flexibility and reduce bending fatigue, supporting stable performance in applications with continuous flex, torsion-rated movement, or repetitive motion cycles.
Stable power and signal transmission for motion control systems.
Jacket material options including PVC, PUR, TPE, and other application-driven compounds.
Designs for static installation, continuous flex, and torsion-rated movement.
Oil-resistant, abrasion-resistant, flame-retardant, halogen-free, and chemical-resistant options based on project needs.
Support for high-cycle industrial automation, robotics, machine tools, and material handling systems.
What We Can Customize
No two servo systems are exactly the same, which is why custom cable design is often necessary for reliable long-term performance. Cable selection is typically influenced by conductor size, voltage demand, shielding level, bending radius, movement pattern, temperature exposure, and the presence of oils, chemicals, or high electrical noise.

Twisted pair design and shield coverage.
Foil shield, braid shield, or combined shielding structure.
Insulation materials for electrical and environmental performance.
Outer jacket materials such as PVC, PUR, or TPE.

Servo Cable Construction Considerations
A reliable servo cable is not defined by one single material; it depends on how the conductor, insulation, shielding, fillers, and jacket work together under real operating stress.
Industry guidance consistently points to fine-stranded copper conductors, stable insulation systems, and suitable shielding structures as key factors in cable performance, especially where feedback accuracy and dynamic motion are involved.
Conductors
Fine-stranded copper conductors are widely used in motor and servo cables because they help improve flexibility and reduce fatigue in repetitive motion applications. Conductor size should be selected according to motor power, voltage drop considerations, and system requirements.
Insulation
Common insulation choices include PVC, PE, PP, and TPE, with the final selection depending on signal stability, flexibility, and environmental resistance needs. For feedback-related applications, insulation quality is particularly important because low-voltage signals are more sensitive to interference and leakage.
Shielding
Shielding helps protect both power and signal conductors from EMI, crosstalk, and electrical noise. Depending on the application, servo cables may use foil shielding, braided copper shielding, or combined structures, and some feedback cable designs may require both pair-level and overall shielding to maintain signal accuracy in high-noise environments.
Jackets
Outer jackets protect the cable against abrasion, oils, chemicals, and mechanical wear. PVC is commonly used as a versatile standard option, while PUR and TPE are often selected for stronger abrasion resistance, flexibility, and demanding motion environments.

Frequently Asked Questions
A servo motor cable is a cable used in motion systems to connect the servo drive and the motor, supporting power transmission and, in many cases, feedback signal transmission required for precise control.
Motor cables mainly deliver power between the drive and the motor, while servo cables typically include power conductors plus low-voltage signal pairs for transmitting feedback to the drive.
A servo feedback cable is used to transmit feedback signals that help the control system monitor motor position, speed, and motion accuracy. Because these signals are sensitive, feedback cables often need stronger shielding and stable insulation design.
A hybrid servo cable combines power supply and signal transmission in one cable structure, which can reduce cable routing complexity and replace separate encoder cable runs in some systems.
Yes. Servo and motor cables used in moving systems may need continuous flex or torsion-rated construction depending on whether the application involves repeated bending, cable chain movement, or multi-axis twisting motion.
Common jacket options include PVC, PUR, and TPE, with the best choice depending on abrasion resistance, flexibility, temperature range, and exposure to oils or chemicals.
To recommend a suitable custom servo cable solution, it is helpful to provide application type, movement condition, conductor size, core count, voltage level, shielding requirements, temperature range, jacket preference, and any connector or assembly requirements.
