Kollmorgen B-606-A-B1
Product Overview:
The B-606-A-B1 is a brushless DC servo motor from Kollmorgen’s B-series lineup. The “606” denotes a larger frame than the 404 series (approximately 60 mm × 60 mm body cross-section). The “A” indicates short stack length within the 606 frame. The winding code “B1” specifies the electrical characteristics. This motor delivers higher torque than the 404 series while maintaining the compact B-series form factor.

Advantages:
- 60 mm frame delivers 0.95 Nm continuous — 3.4× the torque of B-404 in similar envelope
- 48 VDC, 10 A continuous — high power density for compact size
- 1000-line encoder — 2× resolution of 404 series, better low-speed velocity control
- Short stack (A) — lower axial length, fits into slim profiles
Applicable Industries:
- Robotics — medium-torque joint actuators, gripper drives
- Medical — hospital bed drives, imaging table motion
- Packaging — servo-driven cutting, sealing, labeling axes
- AGV/AMR — wheel drive motors
- Collaborative Robots — arm joint actuators
Installation Requirements:
- Mount using 4-hole flange per B-606 dimensional drawing (M4 mounting holes)
- Shaft coupling: flexible coupling rated for minimum 5 Nm, max misalignment 0.15 mm radial
- Wiring: 6 motor leads + 3 encoder leads (1000-line incremental)
- Thermal: rated for natural convection at continuous torque; forced air required for peak operation
Usage Notes:
- Winding B1 is 48 VDC specific — do not apply 24 VDC (will not reach rated speed/torque)
- Encoder is 1000 lines/rev — configure drive for 4000 counts/rev (×4 decoding) for best resolution
- 12 mm shaft with 1.0 mm keyway — use matching coupling hub
- Continuous operation above 40°C ambient requires 10% torque derating per 10°C above 40°C
