M850 Series Servo Motor
M85AS190 Physical View
1. Product Overview ⚙️
Lenze M85AS190L256SPDLC M850 Long-Stack High-Torque Permanent Magnet Synchronous Servo Motor
This German-manufactured heavy-duty servo motor belongs to Lenze M850 modular servo platform, designed as high-torque motion execution core for large inertia heavy-load automation equipment.
It converts digital motion commands from Lenze i700 / i950 cabinet servo drives into stable high-output torque & low-speed rotation, realizing heavy-load positioning, palletizing lifting, high-tension winding and high-inertia reciprocating cutting control.
Full Model Code Decoding
M85AS190: M850 series, 190mm IEC standard flange synchronous servo motor
L25: Long stator stack, rated speed 2520 rpm
6: Multi-turn digital absolute HIPERFACE DSL encoder
SP: Built-in 24V DC spring-applied holding brake for vertical lifting axes
DLC: One Cable Technology (OCT) single hybrid cable integrated power + brake + position feedback signals
The long L stack design delivers the maximum continuous torque within M85AS190 frame size, equipped with integrated holding brake and OCT single cable interface to simplify cabinet wiring layout. Standard 190mm flange perfectly matches Lenze G700 / G800 heavy-duty planetary gearboxes for wide torque amplification.
2. Core Advantages & Key Features ✅
Long Stack Maximum Continuous Torque Output
Extended long stator stack provides 67 Nm standstill torque, 35 Nm rated torque and 200% short-time overload capacity, ideal for heavy inertia vertical lifting, palletizing and metal cutting loads.
Integrated Spring Holding Brake (SP Version)
Built-in 24V DC electromagnetic fail-safe brake locks output shaft rigidly during power failure, eliminates workpiece falling risk for vertical axes of palletizers, lifting handling robots and vertical machining equipment.
One Cable Technology (OCT) HIPERFACE DSL Encoder
Single unified hybrid cable integrates power circuit, brake control, KTY temperature sensor and high-resolution multi-turn absolute position feedback; cuts wiring quantity, reduces fault points and cabinet wiring cost by over 50%.
Optimized segmented stator winding and rare-earth rotor magnetic circuit minimize torque fluctuation, ensures consistent precision for heavy tension winding and thick material cutting without speed jitter.
Dual Thermal Overheat Protection
Built-in KTY84 temperature sensor + PTC thermistor dual monitoring, real-time winding temperature feedback to servo drive for automatic derating and shutdown protection against coil burnout.
Full IP65 Industrial Protection Grade
Complete motor housing, flange and quick connector reach IP65 dustproof & splash-proof rating, resistant to workshop metal cutting fluid, dust and regular cleaning water splashes.
Modular Heavy-Duty Gearbox Matching
Standardized 190mm IEC B5 flange directly assembles with Lenze G720/G750/G800 heavy planetary reducers to expand output torque up to hundreds of Nm.
Full Compatibility with Lenze Servo Ecosystem
Perfectly matched with Lenze i700 and i950 high-performance servo inverters, supports electronic cam, print mark registration, multi-axis synchronous and heavy-load positioning control functions.
