Product Overview
▔▔
The Rexroth MSK series (IndraDyn S) represents Bosch Rexroth's flagship line of compact, high-dynamic synchronous AC servo motors designed for modern industrial automation. Engineered for extreme precision, continuous high torque density, and fast dynamic response, the MSK motor series integrates seamless motion control across heavy-duty and high-accuracy applications.
Key Advantages
▔▔
- High Torque Density & Wide Power Range: Delivers maximum continuous torque up to 240 Nm and peak torque up to 495 Nm across frame sizes MSK030 through MSK133, providing high power output in a compact housing.
- High-Precision Optical & Capacitive Encoders: Supports single-turn and multi-turn absolute encoder systems (up to 24-bit resolution) with EnDat, Hiperface, and Drive-CLiQ interfaces for fine positioning accuracy.
- Flexible Thermal Management: Configurable with natural convection (standard), forced surface fan cooling, or liquid cooling for extended continuous duty cycles and extreme load conditions.
- Integrated Electronic Nameplate: Automatically transmits motor configuration parameters to connected Bosch Rexroth IndraDrive units for fast plug-and-play setup.
- Robust Environmental & Mechanical Protection: Standard IP65 rating (optional IP67), Class 155 (F) winding insulation, and durable FKM (Viton) shaft seals resistant to hydraulic oils and aggressive industrial fluids.
- Versatile Electrical & Shaft Options: Features 240-degree rotatable plug connectors (M23 to M58), optional electrically released holding brakes, plain or keyway shafts, and reinforced bearing arrangements.

Applications
▔▔
- Servo-Hydraulic Power Units (e.g., Plastic Injection Molding Machines): The MSK motor directly drives variable or fixed-displacement internal gear pumps, executing precise speed-regulated pressure and flow control during clamping, injection, and holding cycles.
- Hydraulic Metal Pressing & Stamping Machinery: Serves as the primary drive unit for modern hybrid-servo press systems, managing rapid acceleration, precise pressure hold-times, and rapid stroke retraction.
- CNC Machine Tool Axis Feeds: Drives ball screw assemblies and rotary indexing tables where high positioning resolution, low heat generation, and dynamic braking are critical.
- Automated Material Handling & Robotics: Applied in heavy-payload gantries, transfer arms, and dynamic packaging lines requiring fast start-stop duty cycles.
