The 9-Core Motor Wire is a multi-conductor flexible cable designed to carry combined motor power, feedback/control, brake, and PE ground between a drive/controller and servo, stepper, BLDC, or small AC motor in a single jacket. This 9-core layout serves as the industry-standard solution for 3-phase windings, encoder connections, power/ground, brake, and shield drain - eliminating the need for multiple separate cables in cable carriers. Available as raw cable by the meter or as pre-cut motor lead wire with ferrules and plugs.

Compared to 3-core power + separate encoder cable: 40% less drag-chain cross-section, no tangling
Compared to single 9-core unshielded: Prevents servo drift and EMI trips on long runs
Compared to PVC RVV 9-core generic: PUR Class-6 servo grade lasts 10* longer in moving installations
Raw 9-core by the meter allows exact length cutting and custom plug fitting with no MOQ penalty
