2. Core Advantages & Key Features ✅

1. Short Compact Stack Lightweight Design
   
   
   Short stator stack structure reduces overall motor weight and installation length, ideal for compact machinery with limited mounting space, lower rotor inertia for ultra-fast dynamic response.
2. One Cable Technology (OCT) Absolute Encoder
   
   
   Single hybrid cable integrates power circuit, temperature sensor and high-resolution multi-turn position feedback; eliminates separate encoder wiring, cuts wiring cost and reduces potential circuit fault points.
3. Smooth Low-Torque-Ripple Rotation
   
   
   Optimized stator winding and magnetic circuit design minimize torque fluctuation, ensuring consistent precision for printing, labeling and film tension control with positioning repeatability up to ±0.001°.
4. Full IP65 Industrial Protection Grade
   
   
   Entire motor housing, flange and quick connector reach IP65 dustproof & splash-proof standard, resistant to workshop dust, cooling cutting fluid and cleaning water splashes.
5. Modular Gearbox Compatibility
   
   
   Standardized 140mm IEC output flange supports direct assembly with Lenze G500/G720/G750/G800 planetary reducers for flexible torque amplification.
6. Integrated Dual Thermal Protection
   
   
   Built-in KTY temperature sensor + PTC thermistor dual overheat monitoring, real-time winding temperature feedback to servo drive for automatic overheat protection to avoid coil burnout.
7. Wide Compatibility with Lenze Servo Ecosystem
   
   
   Fully matched with Lenze i700 cabinet servo inverters and i950 high-performance drives, supporting electronic cam, print mark registration and multi-axis synchronous motion functions.
8. Maintenance-Free Bearing System
   
   
   High-temperature long-life sealed grease bearings, no periodic lubrication required for 20,000+ hours continuous operation.
