Electric Bike E Scooter Motor Connector Cable Waterproof 9 Pin Motor Cable
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.
- Single cable solution for power, feedback, and brake functions
- High-flex rating for drag chain applications with 5-8 million bend cycles
- EMI-safe shielded options for noise reduction in servo positioning
- Size-matched configurations for various motor power requirements
- Wide voltage range from 300/500V to 600/1000V
- Extended temperature ranges for diverse operating environments
- Color-coded cores for error-free installation
- Reduced BOM compared to multiple cable solutions

- Conductor: Class 5 / Class 6 stranded bare or tinned copper, 0.14-6 mm² per core
- Common builds: 9*0.5 / 9*0.75 / 9*1.0 / 9*1.5 mm² (metric), 9*16 AWG (imperial high-temp)
- Insulation: PVC / PE / PP / FEP; Jacket: PVC (fixed) / PUR (flex) / silicone (high temp)
- Shielding: unshielded (power only) / tinned braid / braid+Al-foil (double, for encoder pairs)
- Ground: 1 core yellow-green PE, or separate bare drain wire under shield
- Standards: IEC 60228, IEC 61076 (if plugged), EN 50525, VDE 0285, UL AWM, RoHS/REACH
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
