The Bosch Rexroth Indramat MDD025B-N-100-N2G-040FR1 is a high-precision digital AC servo motor in the MDD Synchronous Motors series designed for demanding motion control applications. This permanent-magnet motor integrates an encoder for commutation, rotor position, and speed control, delivering reliable closed-loop performance. It supports a nominal speed of 10000 min⁻¹ and features a standard housing optimized for installation flexibility. Equipped with a blocking brake rated at 1.0 Nm holding torque, the MDD025B-N-100-N2G-040FR1 ensures secure axis locking under power loss. The motor’s plain shaft and resolver feedback system provide robust, maintenance-free operation in industrial environments.
The MDD025B-N-100-N2G-040FR1 builds on a comprehensive set of technical specifications: it utilizes a Standard balancing grade and a Motor Length Code B to achieve an optimal balance between torque density and compact form factor. The Motor Size 025 establishes a centering diameter of 40 mm, while the continuous torque at standstill is rated at 0.60 Nm. Feedback is delivered via a high-resolution Resolver feedback system, eliminating the need for battery-backed encoders. Connection is handled through a right-side Connector interface with a standard (without side B) Shaft End and no additional Shaft Seal. The motor’s overall design conforms to standard mounting dimensions and a plain shaft configuration for compatibility with a broad range of gearboxes and couplings.
Operationally, the MDD025B-N-100-N2G-040FR1 demonstrates consistent performance across varying loads, supported by precise speed control up to its rated 10000 min⁻¹. The integrated blocking brake engages rapidly to secure the rotor when the drive is de-energized, leveraging the 1.0 Nm torque capacity to maintain system position. Continuous torque at standstill of 0.60 Nm ensures the motor can sustain static loads without drift, while resolver feedback provides real-time commutation and fault detection. Standard shaft balancing minimizes vibration at high speeds, enhancing longevity and reducing acoustical noise. The connector-based power and feedback interface enable quick installation and simplified cabling in compact control cabinets.
Integration into digital drive controllers is streamlined by compliance with Bosch Rexroth Indramat communication protocols and firmware interfaces. The motor’s plain shaft and centering diameter of 40 mm facilitate direct coupling to servo amplifiers and gearboxes without custom adaptors. Its robust resolver feedback eliminates homing routines and supports rapid commissioning in automated assembly, packaging, CNC machinery, and robotics. Target applications include precision pick-and-place systems, indexing tables, and any high-speed axis requiring secure holding brakes and accurate position feedback within the MDD Synchronous Motors product family.
