3. Product Specifications & Features
3.1 Core Specifications
The 65WKS-M310/22 is optimized for medium-power motion control, with 3.1 kW rated power and 19.8 N·m rated torque fitting mid-sized automation tasks (e.g., CNC lathe axis drives). Its 1500 rpm rated speed and 59.4 N·m peak torque (10s) enable short bursts of high power for acceleration/deceleration, critical for dynamic applications like robotic pick-and-place.
The 220 V AC 3-phase design integrates with standard industrial servo drives, while the 2048-line incremental encoder ensures precise position feedback (±0.018° resolution). The IP65 protection class resists dust and water splashes, suitable for factory floor environments, and the IEC 132 flange mounting simplifies installation into existing machinery.
3.2 Key Features
- High Torque Density: Permanent magnet design delivers 19.8 N·m rated torque in a compact form, saving installation space.
- Dynamic Performance: Low inertia (0.085 kg·m²) enables fast acceleration/deceleration, reducing cycle times for automation tasks.
- Reliable Protection: IP65 rating and wide temperature range (-15°C to +40°C) ensure durability in harsh factory conditions.
- Precision Feedback: 2048-line encoder provides accurate position control, meeting tight tolerance requirements (e.g., semiconductor wafer handling).
- Drive Compatibility: Works seamlessly with Kollmorgen AKD/AKM servo drives, eliminating integration issues.
