Kollmorgen AKM53G-SSCNR-02
-
-
Product Name: AKM5x Series synchronous brushless servo motor (400 V class)
-
Product Introduction: Compact high-torque-density permanent-magnet AC servo motor from the AKM family, designed for direct coupling to machine loads without transmission backlash.
-
Technical Specifications:
-
Frame size: 53 (approx. 108 mm flange)
-
-
Detailed content
-
-
Continuous stall torque: 11.37 Nm
-
Peak torque: up to 101 Nm (max rating depending on winding)
-
Maximum mechanical speed: 2520 rpm
-
Rotor inertia: 0.00091 kg·m²
-
Shaft diameter: 24 mm
-
Feedback: SSCNR code = single-turn absolute encoder, standard connector, no brake, keyway shaft
-
Voltage class: 400 V AC (DC bus up to 320 V typical for AKM5x)
-
-
Functional Features: Low cogging through optimized magnet geometry; silicon-steel laminations; high peak acceleration; maintenance-free bearings; IP65 housing standard.
-
Application Scenarios: CNC feed axes, packaging machinery, printing presses, robotics, material handling.
-
Material & Structure: Aluminium housing, electrical steel laminations, rare-earth permanent magnets, sealed ball bearings, standard metric shaft with key.
-
Working Principle: Three-phase stator windings excited by servo drive create rotating field; rotor permanent magnets follow field position reported by encoder for closed-loop commutation.
-
Installation Requirements: Flange or foot mounting with concentric shaft alignment; avoid radial shaft loads beyond catalogue limits; use flexible coupling.
-
Usage Notes: Do not disconnect motor power under load without drive disable; verify encoder cable shielding; observe maximum ambient temperature 40 °C (IP65 version).
