MDD Synchronous Motors
The Bosch Rexroth Indramat MDD021A-N-100-N2G-032MA0 is a precision-engineered member of the MDD Synchronous Motors lineup, designed to meet rigorous industrial requirements. This Motor for digital drive controllers features a compact Motor Length Code A configuration and a precise Centering Diameter of 32 mm to ensure seamless integration into automated systems. As a digital AC servo motor with a permanent-magnet rotor, it delivers consistent performance while offering a lightweight footprint. Manufactured by Bosch Rexroth Indramat, this model is supplied Without blocking brake, simplifying maintenance and reducing system complexity.
Rugged construction and advanced electrical characteristics define the technical capabilities of this servo motor. It achieves a Nominal Speed of 10000 min⁻¹ and sustains a Continuous Torque at Standstill of 0.15 Nm for steady operation in low-speed, high-torque applications. The unit’s Resolver feedback system provides high-resolution rotor position sensing, while the integrated encoder supports precise commutation and speed control loops. A Standard Balancing configuration minimizes vibration, and the Standard Housing ensures durability in harsh environments. The motor’s Motor Size 021 designation reflects a balance between compact dimensions and torque density, accommodating space-constrained designs without sacrificing performance.
Operational reliability is further enhanced by thoughtfully engineered mechanical features and connection options. The Shaft Type keyway adheres to DIN 6885 standards, offering secure torque transmission with robust axial retention. A Standard (without side B shaft end) Shaft End simplifies coupling arrangements, while the Without shaft seal design eases cleaning procedures and prevents seal wear in high-cycle operations. Electrical interfacing is streamlined via a Connector on Side A, enabling rapid installation and straightforward field wiring. The resolver-basedMotor Feedback supports closed-loop commutation and real-time speed adjustment, ensuring stable control and optimized energy efficiency under variable load conditions.
Integration of the MDD021A-N-100-N2G-032MA0 into digital drive architectures is seamless, thanks to its compatibility with Bosch Rexroth Indramat controllers and industry-standard interface protocols. Its Connector-type power input and standardized footprint facilitate drop-in replacement or new system designs, reducing engineering overhead. Ideal for CNC machinery, pick-and-place systems, packaging lines, and robotics applications, this servo motor delivers reliable performance in demanding automation environments. By combining precision feedback, compact mechanical design, and versatile connectivity, the MDD series motor provides engineers with a robust solution for enhancing motion control applications.

Frequently Asked Questions
What are the implications of the 0.15 Nm continuous torque at standstill for positioning accuracy?
With 0.15 Nm standstill torque the motor can hold small loads securely without motion when powered, which helps maintain position under disturbances but may require gearing or leverage reduction if load torque approaches that value. For dynamic motion, designing so that peak torques never drive the motor into its standstill limit avoids losing steps or creeping.
How does the nominal speed of 10,000 min⁻¹ affect cooling and thermal management?
At high speed, windage losses and air friction generate heat, so cooling must be sufficient (through ambient airflow or forced cooling) to avoid overheating; thermal time constant becomes critical in duty cycles. If the motor is enclosed or mounted in tight cabinets, plan extra ventilation or de-rating under continuous high-speed operation.
How would the absence of a shaft seal affect the motor’s use in dusty or moist environments?
Without a shaft seal, contaminants like dust, moisture, or coolant can enter around the shaft, potentially damaging bearings or degrading the keyway and lubrication. For such environments, external sealing or protective enclosures are advisable to maintain long-term reliability.
How does the manufacturer Bosch Rexroth’s part MDD021A-N-100-N2G-032MA0 perform in terms of rotor inertia and how does that impact motion control?
The rotor inertia is relatively low (given its compact design and “A” length) which allows quicker acceleration and deceleration with less overshoot; however, low inertia also means less smoothing effect against disturbances. In feedback-loop tuning, expect sharper response but you’ll need to manage vibration and ensure drive electronics are capable of crisp current control.
What are some B2B applications where this motor’s characteristics (speed, torque, size) offer real advantages?
High-speed pick-and-place robotics, packaging machines, and small CNC tools benefit because this motor offers high RPM in a compact form, enabling fast cycles with modest torque while saving space. Also in semiconductor equipment or lab automation where precision, low inertia, and clean mechanical coupling are critical, its resolver feedback and keyway shaft are assets.
