MDD093B-N-020-N2M-130PR2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093B-N-020-N2M-130PR2 servo motor is part of the renowned MDD Synchronous Motors series, offering precision motion control for demanding industrial applications. This digital AC servo motor integrates a permanent-magnet design with an Integrated multiturn absolute encoder to ensure accurate commutation, rotor position, and speed regulation. With a Motor Size of 093 and a Motor Length Code of B, this model achieves a balanced form factor. It features a robust Holding Brake Torque of 22 Nm via a blocking brake, and a Centering Diameter of 130 mm, providing secure mounting and superior mechanical stability. The primary function of this motor is to deliver reliable torque and position feedback for automated systems requiring high dynamic response and repeatability.
In-depth technical parameters highlight the MDD093B-N-020-N2M-130PR2’s capabilities: it operates at a nominal speed of 2000 min⁻¹ and produces a continuous torque at standstill of 14.5 Nm. The motor feedback is handled through a Digital servo feedback (DSF) system, ensuring minimal latency between command input and rotor response. The shaft, designed with a keyway per DIN 6885 sh. 1, 8-68 Edition, provides a dependable mechanical interface for direct drive applications. The integrated encoder not only supports multiturn absolute positioning but also simplifies system calibration and reduces installation complexity.
Additional design features enhance compatibility and durability. The housing is of Standard construction with Standard balancing and includes a shaft seal to protect internal components from contaminants. Connection is facilitated via a right-oriented Connector interface, promoting straightforward integration with digital drive controllers. The standard shaft end design simplifies coupling to gearboxes or load elements without requiring custom adapters. This motor adheres to rigorous industry practices and leverages Bosch Rexroth Indramat’s engineering expertise. Its combination of accurate digital feedback, robust braking, and reliable mechanical interfaces makes it an excellent choice for high-precision, energy-efficient industrial automation systems.

Frequently Asked Questions
What mechanical damping behavior can be expected from the MDD093B-N-020-N2M-130PR2 in interpolated motion profiles?
It has a rotor moment of inertia of 29 x 10⁻⁴ kg·m², offering balanced dynamic response. This supports accurate acceleration without overshoot in mid-inertia systems.
How does this motor perform in applications requiring stable rotational velocity?
Its nominal motor speed is 2000 min⁻¹, suitable for consistent mid-range motion. This benefits servo axes in packaging, positioning, and general automation tasks.
What control loop tuning considerations apply when torque linearity is critical?
With a torque constant of 0.86 Nm/A at 20 °C, current-to-torque behavior is highly predictable. This ensures responsive control in low-speed, torque-sensitive operations.
What overload behavior should be considered when deploying this motor under transient loads?
It can deliver up to 45.1 Nm of theoretical maximum torque. Drive protection must be tuned to allow this peak without triggering shutdown during brief demand spikes.
What structural durability features support long-term reliability in automated machine environments?
The motor is housed in a standard industrial enclosure. It provides consistent mechanical integrity across varied mounting orientations and ambient conditions.
