Kollmorgen Goldline B & M Series Permanent Magnet Servo Motors
The Kollmorgen Goldline Servo Motor Series (featured model: B-202-A-11 2.5 Nm 4000 RPM) is Kollmorgen's classic permanent magnet AC servo motor platform, widely recognized for its rugged thermal construction, high peak acceleration torque, and industrial reliability. Divided into the **Goldline B-Series** (low-inertia rotor for rapid start/stop indexing) and **Goldline M-Series** (medium/high-inertia rotor designed for high load inertia matching), these motors incorporate high-coercivity permanent magnets, Class H winding insulation, MS style military connectors, and heavy-duty IP65 housing seals. Covering continuous stall torque ratings from 0.84 Nm up to 120 Nm across 6 primary frame sizes, Goldline motors utilize factory-aligned 2-pole resolvers for robust feedback in harsh vibration environments. WE DRIVE HONGKONG LIMITED provides technical sourcing, exact part number decoding, factory repair-replacement units, and 100% compliant mechanical/electrical upgrade paths mapping legacy Goldline motors to modern **Kollmorgen AKM and AKM2G series servo motors**.

Expert Technical Sourcing & Legacy Motion System Integration Notes
When servicing older Kollmorgen SERVOSTAR 600 or BDS5 drives operating Goldline motors, upgrading to modern AKM servo motors paired with AKD digital amplifiers delivers immediate performance benefits: 30% reduction in motor footprint, elimination of feedback drift, automated WorkBench autotuning, integrated Safe Torque Off (STO SIL2/SIL3), and complete physical interchangeability via standard mounting flanges. Simply supply us with your existing Goldline nameplate part number (e.g., B-202-A-11 or M-403-B-21), and our technical engineering team will deliver a 100% compliant replacement specification and proposal.
