Kollmorgen B-606-A-B1-B2E
Product Introduction:
The B-606-A-B1-B2E is a brushless DC servo motor from Kollmorgen’s B-Series product line. The “606” indicates a 60 mm flange size with a 6 mm shaft diameter. The suffix codes specify the winding variant (“A”), commutation type (“B1” = Hall sensor commutation), and feedback configuration (“B2E” = single-turn absolute encoder with EIA-422 output). This motor is designed for precision motion control in compact form-factor applications.

Code Breakdown (B-606-A-B1-B2E):
| Code Segment | Meaning |
|---|---|
| B | B-Series Brushless DC Motor |
| 606 | 60 mm flange, 6 mm shaft |

Structural Features:
- Aluminum alloy housing with black anodized finish
- Precision ball bearings (sealed, grease-lubricated for life)
- Keyed shaft with D-cut for set-screw locking
- M23 connector (12-pin) for power and feedback
- Integrated Hall sensor PCB mounted on stator
Functional Features:
- Hall sensors provide reliable commutation at standstill and low speed
- Absolute encoder retains position after power-off (no homing required for single-turn)
- High torque density in compact 60 mm package
- Low cogging torque for smooth low-speed operation
Applicable Industries:
- AGV (Automated Guided Vehicle) drive wheels
- Conveyor roller drives
- Packaging machine axes
- Medical device actuators
- Laboratory automation
- Textile machine drives
Installation Requirements:
- Mount using M4 screws on 60 mm flange bolt circle (4-hole pattern, 50 mm PCD)
- Use flexible coupling (jaw or bellows type) — max misalignment: 0.15 mm radial, 0.15° angular
- Ground motor housing to drive chassis via dedicated wire
Usage Notes:
- Do not apply axial thrust loads exceeding 50 N
- Hall sensor wires: Red = +5V, Black = GND, Green/Yellow/Blue = H1/H2/H3
- Encoder wires: A+, A-, B+, B-, Z+, Z-, +5V, GND (per RS-422 standard)
- Maximum ambient temperature: 40°C for continuous rated operation
