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.

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
