Shaft TypeCylindrical with keyway, DIN 6885-1

Shaft Diameter8 mm

Shaft Length18 mm (keyway)

Weight: Approximately 0.35 kg

Insulation Class: Class F (155°C)

BearingsMiniature ball bearings, sealed

Winding CodeANC = Specific winding for high-speed, low-torque application

Electrical Connection: M8 connector, 8-pin

Voltage Rating48 VDC bus (internal drive)

Key Features:

  • Smallest AKM frame — ultra-compact integrated servo
  • High speed capability (6000 RPM) for small-diameter applications
  • No encoder — Hall commutation only, suitable for velocity/torque control
  • No brake — minimal weight configuration

Applicable Industries: Medical devices, semiconductor equipment, small robotics, optical systems, laboratory automation, drone actuators

Installation Requirements:

  • Mount via B5 flange (2× M3 holes) or adhesive mount
  • Bolt torque: 1.5 Nm (M3)
  • Coupling: Flexible coupling only — rigid coupling damages bearings at high speed
  • Cable: M8 connector, 3 m standard

Usage Notes:

  • Do not exceed 6000 RPM — catastrophic magnet failure above this speed
  • NR (no encoder) — positioning accuracy limited to open-loop or Hall-based commutation
  • Operating temperature: 0°C to +40°C
  • Not suitable for applications requiring holding torque without power
  • For position control, select encoder variant: AKM31C-ANENR-0
