Kollmorgen AKM22E-ANC2R-00
Product Type: Brushless DC (BLDC) Servo Motor with Integrated Encoder
Product Overview:
The AKM22E-ANC2R-00 is a compact, high-torque-density servo motor from Kollmorgen’s AKM product line. The “22E” denotes a 22 mm frame size (approximate outer diameter), “ANC” indicates an Absolute Single-Turn EnDat 2.2 encoder, “2R” denotes a shaft with keyway and O-ring seal, and “00” is the standard winding variant.

Functional Features:
- Ironless rotor design — zero cogging torque, ultra-smooth motion
- High torque-to-inertia ratio — rapid acceleration/deceleration
- Integrated absolute encoder — no homing required after power loss
- Preloaded bearings — high axial and radial load capacity
- Hall sensors for commutation (3-phase)
- Kollmorgen AKM Workbench for motor identification and tuning
Applicable Industries:
Surgical robots, semiconductor wafer handlers, optical alignment systems, drone gimbals, precision valve actuators, laboratory automation, aerospace actuators
Installation Requirements:
- Align motor shaft to load using flexible coupling; max misalignment: ≤0.05 mm angular, ≤0.1 mm radial
- Apply torque-controlled fasteners: M4 × 8 mm, 1.5 Nm max
- Ensure connector is fully seated and locked before powering
- Use torque-limiting coupling to protect shaft from shock loads
Usage Notes:
- Do not operate above rated voltage; overvoltage causes irreversible demagnetization
- Maximum continuous duty at rated torque; derate linearly above +50°C ambient
- Encoder cable must be shielded twisted pair; max length 10 m
