MSK075C

Product Overview

▔▔
The Rexroth MSK075C is a high-performance synchronous servo motor and drive unit widely integrated into precision variable-speed hydraulic pump systems (such as Rexroth Sytronix systems). Positioned as a medium-frame size industrial drive component, its primary control functions include high-dynamic speed regulation, precise closed-loop torque control, and synchronized flow-pressure ($p/Q$) output management. It is specifically engineered for precision hydraulic control scenarios requiring high repeatability, low noise, and strict energy efficiency, such as injection molding machinery, metal forming presses, and high-precision bending equipment. Key Highlights: Series MSK + Frame Size 075C + High-Dynamic Servo-Hydraulic Drive Integration, delivering exceptional energy savings and precise fluid control.

FAQ

Q1: How do I confirm the exact replacement model for my application?

A: Check the nameplate on your existing motor to verify the complete type code, including the winding code, feedback version, and holding brake specification. You can also send the nameplate photo to our team for instant cross-referencing.

Q2: Does this servo motor require specific filtration or oil compatibility?

A: As an electric synchronous servo motor, it does not use hydraulic oil for internal operation. However, when mounted in close proximity to hydraulic gearboxes or fluid actuators, ensure proper external sealing to prevent oil contamination on the shaft seal.

Q3: Can I replace an older Indramat motor directly with the MSK075C?

A: Direct replacement depends on the mechanical flange dimensions, shaft dimensions, and drive firmware compatibility. Our technical support team can assist you with proper cross-matching and parameter conversion.
