Kollmorgen B-102-A-29-021
-
Product Name: Kollmorgen B-series (Goldline) legacy brushless permanent-magnet servo motor, frame B-102, stack A, winding 29, variant 021
-
Product Introduction: Obsolete low-to-medium inertia brushless servo motor from the Kollmorgen Goldline B-family, designed for rapid acceleration/deceleration. Predecessor of the AKM4 family. Retrofit-compatible to AKD® drives using resolver feedback and manual commutation tuning.
Detailed content
-
Technical Specifications (B-102-A class from Kollmorgen Goldline catalog):
-
Frame: B-102 (approx NEMA 34, ~90 mm flange heritage size)
-
Stack: A (short)
-
Winding: 29 (mid-speed, mid-torque)
-
Stall torque: 2.41 Nm (21.3 lb-in)
-
Continuous torque @ rated speed: 1.15 Nm
-
Peak torque: 7.2 Nm
-
Rotor inertia: 0.0000309 kg·m² (30.9 kg·cm²)
-
Max speed: 7500 rpm
-
Max bus voltage: 320 VDC / 230 VAC class
-
Feedback: Resolver (built-in thermostat for thermal cutout)
-
Insulation: Class H (180 °C)
-
Protection: IP65
-
Brake: Not in -021 variant (shaft/connector config only)
-
-
Functional Features: High torque-to-volume ratio, resolver survives EMI/shock/vibration, Class H windup for sustained overload, low rotor inertia for fast settle.
-
Application Scenarios: Legacy machine tools, older packaging machinery, paper converting retrofits, spindle aux axes built before AKM introduction.
-
Material & Structure: Laminated steel stator, samarium-cobalt or ferrite magnets (depending on manufacture year), cast aluminum endbells, stainless shaft, resolver mounted on rear.
-
Working Principle: Three-phase brushless PM synchronous machine; commutation derived from resolver position through drive or external converter.
-
Mounting Requirements: Flange mount matching original Goldline dimensions; shaft coupling must respect legacy keyway/flat spec; resolver cable shielded separately.
-
Usage Notes: Not plug-and-play with AKD; must manually enter pole count, resolver offset, motor constants in WorkBench. No UL/cURus on very old units; verify nameplate before CE recertification. Replace with Kollmorgen AKM42G-ANC2R or AKM41E for new designs.
