Kollmorgen BR-4500-3017-B
Product Name: BR-Series Brushless Servo Motor (legacy ID-frame line)
Product Introduction: High-performance 3-phase brushless DC servo motor from the discontinued Kollmorgen BR/ID family, intended for demanding industrial motion axes where mid-power torque and resolver feedback are acceptable.
Detailed content
Technical Specifications:
-
Frame size: 3.0 in (76 mm) OD, flange-mounted
-
Rated power: ~60 W (some listings show 6.9 hp / 210 V variant confusion; verified BR-4500-3017-B is a low-voltage 24 VDC unit at 60 W, while the 210 V / 6.9 hp listing refers to a different BR-4500 winding)
-
Rated voltage: 24 VDC (alternative AC windings existed)
-
Rated current: 2.5 A
-
Rated speed: 4500 RPM
-
Rated torque: 0.16 Nm (continuous); stall torque 3.0 Nm; peak 7.8 Nm depending on winding
-
Feedback: 2-pole resolver (standard), optional 2048 CPR incremental encoder on some variants
-
Protection: IP65 (sealed housing, shaft seal)
-
Weight: ~1.2 kg (low-voltage version)Functional Features:
-
Brushless commutation → low maintenance, long bearing life
-
Ribbed aluminum housing for natural convection cooling
-
Neodymium magnet rotor for high dynamic response
-
Standard NEMA/metric hybrid mounting flangeApplication Scenarios: Packaging machinery, semiconductor handlers, robotic joints, lab automation, legacy machine retrofit.Installation Requirements: Flange or foot mount on rigid metal; shield feedback cable; avoid solvent-based cleaners on matte-black paint.Usage Notes: Not plug-and-play with AKD drives without resolver-to-digital tuning; verify winding label before applying bus voltage.
