I. Overview

REXROTH MSK070C-0150-NN-S1-UG0-NNNN is a synchronous servo motor whose core function is to achieve precise three-loop closed-loop control of position, speed, and torque by cooperating with Rexroth servo drives (such as IndraDrive Cs/Ds series), converting electrical signals into stable and accurate mechanical motion. Adopting a permanent magnet synchronous structure, this motor features high torque density, fast dynamic response, and low inertia. Equipped with a multi-turn absolute encoder and a rotatable connection plug, it has a protection class of IP65 (typical value) and is compatible with industrial buses such as Profinet and EtherCAT. Widely used in scenarios requiring strict motion control accuracy and stability, such as CNC machine tools, industrial robots, precision assembly lines, packaging machinery, and automated conveying systems, it serves as a core power executive component in industrial precision motion control systems.

II. Key Features

Ultra-High Precision Motion Control

Equipped with a multi-turn absolute encoder with Hiperface interface, featuring a resolution of 131,072 steps/revolution (typical value). Combined with the drive's three-loop closed-loop control (position loop, speed loop, current loop), the positioning accuracy can reach ±0.001°, and the repeat positioning accuracy is ±0.0005°, meeting the position control requirements of ultra-precision equipment.
Supports electronic gear ratio and electronic cam functions. Motion curves can be flexibly configured through drive software, adapting to complex trajectory control scenarios (such as robot joint linkage, CNC machine tool circular interpolation).

High Dynamic and Power Performance

Rated stall torque of 8.8N·m, peak torque up to 24N·m, and rated speed of 6000rpm (the "0600" in the model corresponds to the speed code). The high torque density design ensures strong power output in a compact volume, enabling rapid response to acceleration/deceleration commands (acceleration time ≤0.1s from 0 to 6000rpm).
Optimized rotor inertia design (typical value 0.0008kg·m²) with a dynamic response frequency ≥1kHz, supporting high-frequency start/stop and forward/reverse switching. Suitable for equipment with extremely high dynamic performance requirements, such as industrial robots and high-speed sorters.

High Reliability and Stable Operation

Adopts high-performance neodymium-iron-boron permanent magnets and Class F insulated windings, with a heat resistance temperature of 155℃. The temperature rise during continuous operation is ≤60K (surface temperature ≤85℃ at an ambient temperature of 25℃), and the Mean Time Between Failures (MTBF) exceeds 15,000 hours.
Protection class IP65, featuring dustproof and water jet protection capabilities, allowing direct installation outside the equipment. It can adapt to harsh industrial environments such as machine tool cutting fluid splashing and dust. The natural cooling design has no fan wear, reducing maintenance requirements.

Flexible Integration and Adaptability

Equipped with a 240° rotatable connection plug, facilitating cable routing and equipment installation, and adapting to narrow space layouts. Adopts standard flange dimensions (60mm frame size), supporting horizontal/vertical installation with strong replaceability.
Compatible with the full range of Rexroth IndraDrive Cs/Ds servo drives, supporting mainstream industrial buses such as Profinet, EtherCAT, and Modbus. It can achieve real-time communication and synchronous control with PLCs and motion controllers, supporting multi-axis linkage functions.

Comprehensive Protection and Diagnostic Functions

Built-in functions such as over-temperature protection, over-current protection, overload protection, and encoder fault detection. The drive provides real-time feedback of motor operating status (temperature, current, speed, fault codes), facilitating quick troubleshooting.
Supports drive auto-tuning function, which automatically identifies motor parameters such as stator resistance, inductance, and inertia, optimizes control algorithms, ensures matching between the motor and drive, and improves system stability and control accuracy.

IV. Working Principle

As a permanent magnet synchronous servo motor, the core working logic of MSK070C-0150-NN-S1-UG0-NNNN is "Command Signal → Drive Processing → Winding Excitation → Electromagnetic Torque → Precise Motion + Feedback Closed-Loop", with the specific process as follows:

Command Reception and Processing

The controller (PLC/motion control card) sends position, speed, or torque commands to the servo drive via industrial bus or pulse signals. After receiving the commands, the drive generates three-phase sine wave drive signals combined with internal control algorithms.

Winding Excitation and Torque Generation

The drive inputs three-phase alternating current into the motor stator windings to generate a rotating magnetic field. The stator rotating magnetic field interacts with the permanent magnets on the rotor, generating electromagnetic torque based on the principle of electromagnetic induction, driving the rotor to rotate synchronously with the rotating magnetic field.

Three-Loop Closed-Loop Feedback Control

Position Loop: The encoder collects rotor position signals in real time, feeds them back to the drive to compare with the command position, and corrects position deviations through PID adjustment to ensure positioning accuracy.
Speed Loop: Calculates the actual speed based on the differential of the position signal, compares it with the command speed, adjusts the output torque, and stabilizes speed fluctuations (speed fluctuation rate ≤±0.1%).
Current Loop: Detects the three-phase stator current, controls the current amplitude and phase, optimizes torque output, and suppresses overload and current distortion.

Dynamic Optimization and Protection

The drive real-time monitors motor parameters such as temperature, current, and voltage. If abnormalities such as over-temperature, over-current, or overload are detected, it immediately cuts off the output or reduces the torque to protect the motor and equipment. At the same time, it dynamically adjusts control parameters through the auto-tuning algorithm to adapt to load changes and ensure operational stability.
