MDD093B-N-020-N2M-130GL1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093B-N-020-N2M-130GL1 from the MDD Synchronous Motors series is a precision-engineered product type Motor for digital drive controllers designed for demanding industrial applications. This motor combines a motor size 093 frame with a motor length code B profile to deliver reliable performance at a nominal speed of 2000 min⁻¹. Its rotor design sustains a continuous torque at standstill of 14.5 Nm, ensuring stable operation under load. Compact yet powerful, this unit meets rigorous standards for automated drive systems.
Engineered for accuracy, the motor features an integrated multiturn absolute encoder paired with digital servo feedback (DSF) for precise position and speed control. A built-in holding brake with blocking brake provides a holding brake torque of 11 Nm to secure loads during power interruptions. The standard balancing and standard housing construction minimize vibration and ensure a long service life. Sealed against contamination, the shaft seal protects internal components, while the plain shaft and standard (without side B shaft end) configuration enable straightforward coupling to gearboxes.
Installation is simplified with a connector-style interface oriented to the left connection direction, reducing wiring time and errors. The motor’s 130 mm centering diameter aligns precisely with standard machine mounts for repeatable assembly. Robust and low-maintenance, this synchronous motor integrates seamlessly into Bosch Rexroth drive ecosystems. Whether used in robotics, packaging, or material handling, the MDD093B-N-020-N2M-130GL1 provides the torque density, accuracy, and reliability essential for modern automation.

Frequently Asked Questions
What limits should be defined in motion controllers using the MDD093B-N-020-N2M-130GL1 during aggressive acceleration profiles?
It supports a theoretical maximum torque of 45.1 Nm, which defines peak mechanical stress. Controllers must cap torque commands accordingly to protect both drive and mechanics.
How does the peak current capacity affect drive selection in servo tuning environments?
This motor draws up to 76.0 A under peak load. Drive amplifiers must support transient currents without exceeding thermal protection thresholds or triggering foldback.
What influence does rotor inertia have on system responsiveness in interpolated motion axes?
It has a rotor moment of inertia of 29 x 10⁻⁴ kg·m², offering a balance between damping and acceleration. It’s suitable for mid-inertia loads with fast cycle requirements.
How does the torque constant impact precision when driving low-speed load profiles?
With a torque constant of 0.86 Nm/A, the MDD093B-N-020-N2M-130GL1 ensures stable low-speed torque control. This allows smooth operation in high-resolution positioning systems.
What thermal considerations apply due to resistive losses in this model under continuous duty?
The winding resistance is 0.77 Ohm at 20 °C, which contributes to I²R losses. Accurate thermal calculations are needed for continuous applications in sealed or warm enclosures.
