Lenze M85AS120S405SPDLC | M850 Series Synchronous Servo Motor

1. Product Overview 🛠️

Model Code Decoding

2. Core Advantages & Key Features ⭐

1. Compact High Torque Density Design
   
   
   Short-length stator structure with high-performance rare-earth magnets, rated continuous torque 4.8 Nm, standstill torque 6.5 Nm. Small body size reduces cabinet and mechanical frame occupation, low rotor inertia enables fast acceleration/deceleration.
2. Ultra-Smooth Rotation Performance
   
   
   Optimized stator winding layout minimizes detent torque, eliminates running jitter and position deviation, meets high-precision positioning and synchronous speed control demands.
3. One-Cable OCT Digital Encoder Feedback
   
   
   Built-in Hiperface DSL single-cable absolute encoder (suffix P), integrates power and feedback signals in one cable, simplifies wiring, reduces on-site wiring cost and signal interference risk, supports multi-turn absolute position tracking without battery backup.
4. Robust Self-Cooled Mechanical Construction
   
   
   Full encapsulated stator and sealed heavy-duty bearings, natural air cooling for S1 continuous operation; IP54 overall protection resists workshop dust and splashing water, suitable for general industrial workshop environments.
5. Quick Plug Connection System
   
   
   Standard straight M23 SpeedTec quick connectors for power and feedback, fast disassembly and replacement without cutting cables, greatly shortening maintenance downtime.
6. Strong Overload & Wide Compatibility
   
   
   Supports 3x short-time overload torque, adapts to frequent start-stop and impact loads. Perfectly matched with Lenze i700 cabinet, i950 cabinet servo drives; compatible with all Lenze standard planetary gearboxes.
7. Food-Grade Smooth Housing Option
   
   
   Smooth aluminum housing without cooling fins, easy to clean, applicable for food & beverage processing equipment with strict sanitation requirements.

6. Installation & Usage Tips 💡

1. This model has no built-in holding brake; for vertical installation or load holding applications, select brake-equipped variant M85AS120S405SFDLC.
2. Adopt dedicated OCT single cable wiring to avoid signal attenuation over long transmission distance.
3. Keep motor housing surface unobstructed during installation to guarantee natural heat dissipation, avoid closed narrow cabinets without ventilation.
4. Match with Lenze i700/i950 servo drives to activate full encoder closed-loop control performance.
5. Regularly inspect M23 plug tightness and bearing operating noise to extend service life.
