Rexroth MSK030C-0900-NN-M1-UG0-NNNN synchronous servo motor

Overview

The Rexroth MSK030C-0900-NN-M1-UG0-NNNN is a high-performance, low-inertia, permanent magnet synchronous servo motor in the Bosch Rexroth MSK series. This series of motors is renowned for its outstanding power density, excellent dynamic response performance and extremely high quality, making it an ideal choice for building high-precision and high-speed motion control systems. It is specifically optimized for use with the IndraDrive series of servo drives from Rexroth and is widely applied in automation fields that require precise positioning and rapid start-stop.

Core features and advantages

1. Extremely high performance and power density
With powerful permanent magnets and high-quality electromagnetic design, it offers extremely high torque output in a compact body size, achieving excellent power and torque density. This enables equipment designers to obtain greater power within a limited space.

2. Outstanding dynamic response
The low rotor inertia design enables the motor to achieve extremely high acceleration and deceleration, shortening the setting time. It is particularly suitable for high-frequency, short-stroke reciprocating motion, significantly enhancing the production cycle of the equipment.

3. High precision and reliability
◦ Built-in single-turn or multi-turn absolute encoders (defined by the “-NN-” section in the model, commonly EnDat 2.2 or HIPERFACE DSL® protocol). It provides high-resolution position feedback to achieve precise closed-loop control. Absolute position information can be obtained without reference points, ensuring positioning accuracy and reliability.

4. Robust industrial design and compatibility:
The sturdy metal casing and precise manufacturing process ensure the stable operation of the motor in harsh industrial environments. The protection grade is usually IP64 or higher, which can effectively prevent dust and water.

As an important component of the Rexroth drive system, it seamlessly integrates with the IndraDrive driver and enables convenient parameter setting, debugging and diagnosis through the Rexroth IndraWorks software platform.

5. Modularization and Flexibility
The suffixes in the model (such as M1-UG0-NNNN) indicate specific options, for example:

▪ Shaft end type (optical key shaft, keyway, etc.)

▪ Connector type (plug direction, pin definition)

▪ Brake (Optional power-off safety brake)

This modular design enables users to make precise selections based on specific application requirements.
