Model Number: AKM54K-CCANDBD
Model Series: AKM Series — Kollmorgen Frameless-Ready Servo Motors
Detailed content
Product Introduction:
The AKM54K-CCANDBD is a compact servo motor from Kollmorgen’s AKM product line, featuring a 54 mm frame size with multi-turn absolute feedback, no holding brake, and a keyed shaft. The model code breaks down as: 54 = frame size, K = length, CC = multi-turn absolute encoder, A = shaft type, N = no brake, D = connector, B = shaft key, D = additional config.
Technical Specifications:
| Parameter | Value |
|---|---|
| Frame Size / Flange | 54 mm (2.13 in) — AKM54 designation |
| Length Code | K = Extended stack length (highest torque in AKM54 family) |
| Encoder Type | CC = Multi-turn absolute optical — 128 turns, 4,096 counts/rev × 128 = 524,288 counts/rev |
| Encoder Technology | Optical glass scale, battery-backed (CR2032) |
| Configuration Code Breakdown | C = Multi-turn absolute, C = Standard winding, A = Keyed shaft, N = No brake, D = Connector type D, B = Keyed shaft confirmed, D = Shaft seal type D |
| Continuous Torque | 1.8 Nm (15.9 lb-in) |
| Peak Torque | 5.4 Nm (47.8 lb-in) |
| Max Speed (Continuous) | 4,000 RPM |
| Peak Speed | 6,000 RPM |
| Rated Power (Continuous) | 0.75 kW (1.01 HP) |
| Peak Power | 2.26 kW (3.03 HP) |
| Voltage Rating | 200–480 VAC (3-Phase) |
| Holding Brake | No (N) |
| Shaft Type | Keyed — DIN 6885, 14 mm diameter, 4 mm keyway |
| IP Rating | IP65 (with optional shaft seal) |
| Insulation Class | Class F (155°C) |
| Weight | Approx. 1.1 kg (2.43 lbs) |
| Ambient Temperature Range | 0°C to +40°C |
| Bearing Type | Sealed deep-groove ball bearings — L10 life 20,000 hours at rated speed |
Structural Features:
- 54 mm aluminum alloy housing — Smallest frame in AKM series; ultra-compact.
- Multi-turn absolute encoder (CC) — 524,288 positions per revolution; 128-turn memory; CR2032 battery-backed.
- Keyed shaft (14 mm, DIN 6885) — 4 mm wide × 2.5 mm deep keyway.
- No holding brake — Lightest configuration in AKM54K family.
- Connector type D — M23 12-pin circular connector (standard Kollmorgen motor connector).
- Shaft seal type D — Lip seal; suitable for clean indoor environments.
Working Principle:
Three-phase AC current in stator windings drives NdFeB permanent magnet rotor. The multi-turn absolute encoder uses a coded glass disc with battery-backed SRAM to store absolute position across power cycles. On power-up, the drive reads the absolute position immediately — no homing sequence required. The encoder resolution of 524,288 counts/rev provides 0.000686° per count at the motor shaft.
Key Advantages:
- Multi-turn absolute feedback — Position known instantly on power-up; no homing required.
- Ultra-compact 54 mm frame — Smallest servo motor in AKM family; ideal for tight spaces.
- No brake = lowest weight (1.1 kg) — Best torque-to-weight ratio in class.
- Keyed shaft — Simple, zero-backlash coupling.
- 524,288 counts/rev — Highest resolution in AKM54 family.
Applicable Industries:
Small robotics (gripper, wrist), Medical device actuators, Lab automation, Semiconductor inspection, Drone gimbal actuators, Camera pan/tilt systems.
Installation Requirements:
- Mount on 54 mm bolt circle (4× M3 bolts).
- Keyway: 4 mm wide × 2.5 mm deep × 14 mm shaft diameter.
- Encoder connector: M23 12-pin, type D — use Kollmorgen P/N 105102 cable or equivalent.
- Ground housing to chassis: ≤ 0.1 Ω.
- Do not apply axial loads > 20 N — bearings are rated for light thrust only.
Usage Precautions:
- Absolute encoder battery (CR2032): Replace every 3 years or when position is lost after power-off.
- Do not exceed 6,000 RPM — encoder and bearing limits.
- No brake installed — vertical axis requires external brake or counterbalance.
- Ambient temperature: 0°C to +40°C; derate torque 1.5% per °C above 40°C.
- Do not use on shafts with shock loads > 2× rated torque — encoder glass scale is fragile.
