MDD025B-N-100-N2G-040MD1

The Bosch Rexroth Indramat MDD025B-N-100-N2G-040MD1 is a high-speed digital AC servo motor from the MDD Synchronous Motors series, designed for precision control in advanced automation systems. This permanent-magnet motor incorporates an encoder for commutation and rotor position feedback, delivering reliable speed and torque regulation. With a nominal speed of 10000 min⁻¹ and integrated resolver feedback, the motor ensures accurate motion profiling under dynamic loads. The unit features a 1.0 Nm blocking brake that provides secure holding capability during power-off conditions and emergency stops. Rugged construction and compact dimensions make this servo motor suitable for space-constrained installations without compromising performance.

Technical specifications for the MDD025B-N-100-N2G-040MD1 are comprehensive and optimized for digital drive compatibility. The motor is designated as Motor Size 025 with a Motor Length Code B and a Centering Diameter of 40 mm, ensuring standardized mounting interfaces. It delivers a continuous torque at standstill of 0.60 Nm and is balanced to Standard grade for smooth operation across its speed range. The housing is constructed to Standard specification, and it is supplied without a Shaft Seal for applications where ingress protection is managed externally. Feedback is provided via a Resolver feedback system, enabling high-resolution commutation. The motor includes a Holding Brake mechanism with Holding Brake Torque of 1.0 Nm for immediate torque lock when required.

Operational features emphasize seamless integration with Bosch Rexroth digital drive controllers and robust mechanical interfacing. The motor’s Shaft Type keyway follows DIN 6885 sheet 1, Edition 8, ensuring secure coupling and torque transmission. A Standard (without side B shaft end) configuration maintains a straightforward mechanical profile on the drive side. Connection is handled via a side B entry, using a connecting cable with coupling unit that supports rapid installation and straightforward maintenance. Rated for continuous operation at Nominal Speed of 10000 min⁻¹, the motor sustains precise torque output under varying load conditions, with minimal cogging and smooth acceleration profiles.

System integration is facilitated through the motor’s status as a Product Type: Motor for digital drive controllers, enabling direct interfacing with Indramat and Bosch Rexroth servo amplifiers. Its compact size and standardized centering diameter streamline retrofits into existing machinery or new machine designs. Target applications include robotics, packaging machinery, CNC equipment, and precision assembly lines where high-speed response and reliable holding torque are critical. The MDD025B-N-100-N2G-040MD1 delivers a balanced solution for automated systems demanding accurate motion control and dependable performance.
