Detailed content
Product Overview:
The M-605-D-B1-B3 is a high-performance AKM servo motor featuring a hollow shaft with clamping hub — enabling direct drive of rotary tables, encoders, and pulleys without coupling backlash. The D-winding delivers maximum torque in the 60mm frame class, while the integrated brake provides fail-safe load holding.

Structural Features:
- Hollow Shaft 25mm Bore: Direct-mount rotary tables, encoders, or timing pulleys — zero backlash
- Keyless Clamping Hub (B3): 6–18mm clamp range — eliminates keyway stress concentration
- Slotless Stator: Zero cogging torque — enables smooth rotation at 0.001 RPM
- Ironless Rotor: Ultra-low inertia — acceleration to 3000 RPM in <50ms
- Preloaded Angular Contact Bearings: L10 life >20,000 hours at rated load
Working Principle:
Three-phase brushless DC motor. Drive commutates current through stator windings based on encoder feedback, creating a rotating magnetic field that drives the ironless rotor. Hollow shaft transmits torque directly to attached load via clamping hub.
Advantages:
- Hollow shaft + clamping hub = zero-backlash direct drive — eliminates coupling, keyway, and backlash errors
- D-winding delivers highest torque in 60mm frame — 4.5 Nm continuous
- Slotless construction = zero cogging — smoothest motion in class
- 8 Nm brake holds heavy vertical loads on power failure
- IP65 — washdown and coolant-splash proof
Applicable Industries:
Rotary Tables (4th/5th axis CNC), Direct-Drive Gimbals, Semiconductor Wafer Stages, Print Cylinder Drives, Camera Turrets, Large Valve Actuators, Robotic Joint Axes
Installation Requirements:
- Mount with 4× M6 screws on 72mm bolt circle (60mm frame)
- Hollow shaft: insert load, tighten clamping hub to 12 Nm using torque wrench
- Maximum radial load: 400N; maximum axial load: 150N
- Brake requires dedicated 24V DC supply — minimum 1A capacity
- Cable bend radius: minimum 5× cable diameter (~40mm)
Usage Notes:
- Clamping hub torque is critical: Under-tightening causes slippage and position error; over-tightening deforms hollow shaft — use 12 Nm torque wrench exclusively
- Brake must be energized before any rotation — de-energizing under load damages brake friction surfaces
- Recommended drive: AKD-T01207-ICA (7A continuous matches motor current) or AKD-B02407-NBS (24A peak for fast acceleration)
- Do not press-fit onto shaft — use clamping hub only (B3 configuration)
- Hollow shaft bore must remain clean — debris causes clamping hub imbalance
