1. Product Overview ⚙️
Lenze M85AS140S406S0DLC M850 Short Stack Permanent Magnet Synchronous Servo Motor
This German-manufactured servo motor belongs to Lenze M850 modular medium-dynamic servo platform, designed as precision motion execution unit for light-to-medium load automation positioning, conveying and packaging equipment.
It converts digital motion commands output by Lenze i700 / i950 servo drives into high-stability rotary torque and speed, supporting closed-loop positioning, multi-axis electronic synchronization, constant tension control and rapid acceleration/deceleration.
The model features short stator stack (S code), no integrated holding brake (S0 code), built-in OCT (One Cable Technology) digital absolute encoder, single hybrid cable integrating power and feedback signals to simplify cabinet wiring layout. Standard IEC 140mm flange perfectly matches Lenze G500/G700/G800 planetary gearboxes to expand output torque range for light inertia industrial loads.
Model Code Decoding
M85AS140: M850 series, 140mm flange synchronous servo motor
S40: Short stator stack, rated speed 3240 rpm
6: Digital absolute multi-turn encoder
S0: Without built-in holding brake
DLC: One Cable Technology (OCT) single cable interface
2. Core Advantages & Key Features ✅
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.
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.
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°.
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.
Modular Gearbox Compatibility
Standardized 140mm IEC output flange supports direct assembly with Lenze G500/G720/G750/G800 planetary reducers for flexible torque amplification.
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.
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.
Maintenance-Free Bearing System
High-temperature long-life sealed grease bearings, no periodic lubrication required for 20,000+ hours continuous operation.
