Motor Connection, Feedback and Transmission Cables
Find servo motor power, encoder and feedback cables for connections between drives and motors. Compare shielded PUR motor cables, symmetrical motor cable constructions and low-capacitance feedback options. Where the equipment supports a combined connection, explore hybrid cables that carry power and signals in one jacket.

Variable Frequency Drive Tray Cables (VFD)
Browse VFD tray cables for inverter-to-AC-motor connections. Compare XLPE-insulated designs with double shielding, symmetrical grounding or an additional screened pair, depending on the construction. Check the voltage rating, conductor size and grounding configuration against the drive specification and the cable route.
How to Specify Servo Motor Cables
Start with the Circuit and Interface
List each connection between the drive and motor. For motor power, note the required voltage, conductor size and protective ground arrangement. For feedback, identify the encoder and the drive’s feedback interface, then record the required core or pair layout and any capacitance limit in the equipment documentation.
Include the drive and motor model numbers. For a hybrid connection, share the connector drawing and pinout so the power and signal elements can be checked together.
Match the Cable to the Installation
Mark the fixed, occasionally moving and continuously bending parts of the route. For a moving CNC axis or cable carrier, record the available bend radius, travel and expected duty cycle. Check the specified moving bend radius and cable diameter against the clearances inside the carrier and at entry points.
Include the operating temperature and any oils, coolants or cleaning agents the jacket will encounter. Confirm that the selected construction suits those conditions.
Confirm Shielding and Installation Ratings
Use the drive and motor documentation to check the shielding and grounding arrangement, permitted cable length and any routing requirements. If a connector or gland determines how the shield is attached, include that detail when comparing cables.
For a VFD tray installation, list the required cable markings. If the project specifies TC-ER or another installation rating, verify that the selected model’s markings and supporting documents cover the intended route.
Servo Motor Cable FAQs
When Should I Choose a Hybrid Servo Motor Cable?
Consider a hybrid cable when the drive and motor support a single connection for power and feedback. Check the connector pinout at both ends, the feedback interface and the permitted cable length before selecting the cable.
Can I Use a VFD Tray Cable in a Moving Cable Carrier?
Check the datasheet for a continuous-flex or cable-carrier rating for the exact cable model. For a moving axis, compare the documented moving bend radius and any travel or cycle limits with the planned installation.
Need a Custom Servo or Motor Cable?
If a standard cable cannot fit your routing space or circuit layout, send the wiring drawing and the drive and motor model numbers. Hulk can review conductor layout, shielding, feedback requirements and jacket materials for a custom motor power, encoder or hybrid cable.
