Product Introduction
Rexroth MSK076C-0450-NN-M1-UG1-NNNN is a compact, high-torque-density synchronous servo motor from the IndraDyn S MSK family. It uses a Hiperface multiturn absolute encoder to deliver accurate position feedback at power-up without homing routines. The integrated holding brake secures the load when power is removed, ideal for vertical axes and gravity-loaded mechanisms. The keyed shaft supports standard coupling installation, and IP65 construction protects the motor from dust and splash in factory environments. Natural convection cooling simplifies wiring and reduces maintenance points compared to fan-cooled variants.

Application Scenarios & Field Experience
This MSK servo motor is widely deployed in high-precision motion axes across discrete manufacturing.
- Machine tools: Feed axes, spindle auxiliary positioning, turret indexing
- Packaging machinery: Forming, sealing, cutting, and label positioning stations
- Robotics and handling systems: Gantry axes, pick-and-place actuators
- Plastic injection molding: Ejector, core pull, and mold transfer control
- Woodworking and printing equipment: High-speed register and cutting controls
A packaging machine had intermittent vertical axis drift after emergency stops. The original motor brake showed degraded holding torque. After replacement with the MSK076C-0450-NN-M1-UG1-NNNN and proper brake wiring, the vertical load stayed locked reliably during power loss, eliminating position shift and scrap parts.
Standard Operating Procedure (SOP) for Quality Control
- Visual Inspection: Check housing, shaft surface, keyway, connectors, and nameplate; verify no scratches, shaft damage, or corrosion.
- Nameplate & Code Decoding: Confirm full part number matches; validate brake, shaft, encoder and speed configuration.
- Shaft & Brake Test: Apply 24 VDC to brake coil; confirm shaft locks when de-energized and releases when powered.
- Encoder Communication Test: Connect to compatible Rexroth drive, verify Hiperface position reading and multiturn count.
- Insulation Resistance Test: Check winding insulation against ground to rule out winding damage.
- Run-in Test: No-load rotation test, monitor vibration and noise, confirm smooth rotation.
- ESD & Protective Packaging: Fit shaft protective cap, pack in foam lined carton with ESD precautions for encoder electronics.
Frequently Asked Questions (FAQ)
Q1: What drive models are compatible with this MSK motor? A: It is designed for Rexroth IndraDrive servo drives. Confirm firmware and encoder parameter matching before commissioning. It is not plug-and-play with other drive brands.
Q2: What is the difference between UG1 and UG0 shaft options? A: UG1 is keyed shaft; UG0 is smooth plain shaft. They are not interchangeable for coupling and pulley mounting.
Q3: Does the holding brake act as a dynamic stop brake? A: No. The integrated brake is only a holding brake for static load retention. It cannot stop a moving axis. Use drive-controlled braking for deceleration.
Q4: What warranty applies to this servo motor? A: 12 months warranty from shipment date. Warranty excludes bearing damage, shaft overload, brake burnout from incorrect voltage, or liquid ingress that breaches IP65 seals.
Q5: Can I replace this motor without re-homing the machine? A: Yes, because it uses a multiturn absolute Hiperface encoder. After replacement, verify offset calibration in the drive to avoid position deviation.
