MDD025B-N-100-N2G-040MR1

The Bosch Rexroth Indramat MDD025B-N-100-N2G-040MR1 is part of the MDD Synchronous Motors series designed for high-precision motion control in industrial automation. This digital AC servo motor combines a permanent-magnet rotor with integrated encoder functions for commutation, rotor position, and speed control. Featuring a built-in blocking brake, the unit delivers reliable holding torque under all operating conditions. With a compact motor size 025 and optimized magnetic circuit, the device supports dynamic acceleration profiles while maintaining stable performance. Developed by manufacturer Bosch Rexroth Indramat under the Indramat brand, this motor meets stringent requirements for repeatability and responsiveness.

The servo motor’s technical foundation rests on a nominal speed of 10000 min^-1, achieved through precision winding and rotor balancing certified as standard balancing. The centering diameter of 40 mm ensures backstop-free mounting and precise coupling to gearheads or machine axes. The motor’s overall envelope is defined by motor length code B and housing: standard finish, facilitating installation in OEM equipment. At standstill, the unit provides a continuous torque of 0.60 Nm, while the integrated holding brake torque of 1.0 Nm secures the axis under power-off conditions. The shaft is configured as a keyway per DIN 6885 sh.1, 8-68 Edition, rated for torsional loads and ensuring secure coupling.

Operational features include a resolver feedback system, which delivers reliable commutation signals and high immunity to electrical noise. The shaft type keyway design supports high torque transfer without slippage, and the absence of a shaft seal simplifies maintenance in clean environments. Connection to digital drive controllers is achieved via a connector interface on the right connection direction, enabling a streamlined cable management path. The motor supports closed-loop velocity and position control modes, leveraging the encoder for fine resolution and rapid response. Its resilience under repeated acceleration cycles makes it suitable for high-frequency indexing in assembly lines and pick-and-place robots.

System integration is seamless with standard digital drive controllers from Bosch Rexroth Indramat, allowing automated tuning and diagnostic feedback. As a dedicated motor for digital drive controllers, the MDD025B-N-100-N2G-040MR1 can be deployed in robotics, CNC machine tools, packaging machinery, and general-purpose automation. The compact footprint and centering diameter convention ensure compatibility with existing mounting interfaces across multiple platforms. Target applications include high-speed rotary indexing, precision gantry systems, and synchronous multi-axis arrays where accuracy and repeatability are critical.
