KUKA 00-186-965 / 00-186-963 AB4582-B Robot Servo Motor Unit | KR C Series Platform
Engineering Background
The KUKA AB4582-B motor family is purpose-engineered for the KR C series robotic arm platform, delivering high-torque, precision-controlled rotational output across demanding industrial cycles. Part numbers 00-186-965 (3.2 kW) and 00-186-963 (2.5 kW) are OEM-designated servo motor units used in axis drives A1–A6, covering the full range of payload classes from 6 kg to 60 kg robots.
Product Positioning
Konmask.com supplies these units to MRO engineers, system integrators, and OEM rebuild shops requiring verified, traceable replacements with minimal lead time. Both variants share the AB4582-B mechanical frame, enabling cross-platform stocking strategies and simplified spare-parts management.

- EMC-compliant wiring harness interface — compatible with KUKA KPP / KSP servo drives
System Architecture & Signal Flow
In the KR C4 architecture, the motor unit interfaces with the KPP 600-20 (power supply) and KSP 600-3×40 (servo drive) via the KCB (KUKA Cabinet Bus). The resolver feedback loop is processed by the DSE-IBS board, which transmits axis position data to the VxWorks real-time kernel at 12 ms interpolation cycles. For KR C2 installations, the motor connects to the KSD 48/10 servo drive module within the controller cabinet.
Signal path: KRC controller → KPP power module → KSP servo drive → Motor power connector (X20) → Resolver feedback (X7) → DSE board → KRC

Technical FAQ
Q: Are 00-186-965 and 00-186-963 interchangeable?
A: No. While they share the AB4582-B mechanical frame, the power ratings and axis assignments differ. Always match the part number to the specific axis and robot model per the KUKA spare parts catalog.
Q: Is re-mastering required after motor replacement?
A: Yes, KUKA standard procedure requires EMD (Electronic Mastering Device) re-mastering after any motor swap, even with absolute encoders, to confirm zero-point calibration.
Q: Can these motors be repaired/rewound?
A: KUKA does not recommend field rewinding. Konmask supplies only complete OEM units to ensure resolver calibration and winding specifications are factory-correct.
Q: What warranty is provided?
A: 12-month warranty against manufacturing defects from date of shipment. Contact support@konmask.com for RMA procedures.
