Material Composition:

  • Stator: Non-oriented silicon steel, epoxy-potted
  • Rotor: NdFeB permanent magnets, NiCuNi plated
  • Housing: Die-cast aluminum, anodized black
  • Shaft: Hardened alloy steel (AISI 4340), keyed
  • Brake: Spring-applied, electromagnetically released

Structural Features:

  • 57mm flange with 4× M4 mounting holes
  • M23 connector (12-pin) carrying power + encoder + brake
  • Keyed shaft (DIN 6885-1, 14×9×40mm)
  • IP65 seal on connector and shaft

Working Principle:
Sinusoidal commutated brushless motor. BiSS-C single-turn absolute encoder provides 14-bit position feedback on every power-up (no homing needed). Drive performs FOC (Field-Oriented Control). Holding brake is spring-loaded; 24VDC energizes coil to release brake for motion.

Key Advantages:

  • BiSS-C encoder — high-speed serial, noise-immune
  • Holding brake included — vertical axis ready out of box
  • 57mm flange — compact footprint
  • Single-cable connection — motor, brake, encoder on one M23
  • Cost-optimized AKM line — full servo performance at lower cost

Applicable Industries:

  • Light industrial automation
  • Medical device actuators
  • Valve automation
  • Small conveyor sections
  • AGV drive wheels

Installation Requirements:

  • Mount with 4× M4 bolts, torque to 2.5 Nm
  • Shaft coupling: ≤ 0.03mm TIR
  • Ambient: -10°C to +45°C
  • Minimum 40mm clearance all sides

Usage Precautions:

  • Brake must be energized before motion starts — running with brake engaged damages motor
  • Do not exceed 5,000 RPM continuously
  • BiSS-C encoder requires termination resistor (120Ω) if cable > 3m
  • Do not use on axes requiring multi-turn position — encoder is single-turn only
