MDD090C-N-030-N2L-130PR1
MDD Synchronous Motors
MDD090C-N-030-N2L-130PR1, Bosch Rexroth Indramat, MDD Synchronous Motors delivers precise motion control in a compact package designed for digital drive controllers. This Motor for digital drive controllers features a Motor Size of 090 and achieves a Nominal Speed of 3000 min⁻¹ under full load, maintaining high rotary precision. The motor’s Motor Length Code C construction and Housing standard design ensure compatibility with existing Indramat installations. Standard balancing and robust construction yield minimal vibration and high dynamic responsiveness.
Incorporating Digital servo feedback (DSF) for closed-loop accuracy, the MDD090C motor offers a Continuous Torque at Standstill of 10.4 Nm and a Holding Brake Torque of 6.5 Nm courtesy of an integrated With blocking brake system. The Centering Diameter of 130 mm and Standard (without side B shaft end) shaft end geometry simplify mounting and coupling. A keyway Shaft Type and With shaft seal configuration protect internal bearings from contaminants, while the right-oriented connector supports a Connection Type of Connector for streamlined wiring. Standard motor feedback enhances integration with Rexroth drive controllers, optimizing tuning and diagnostics.
Engineered for seamless integration into Indramat environments, this motor’s compact dimensions and industry-standard interfaces cut installation time and reduce cabinet footprint. The robust shaft seal and high-precision balancing underscore its reliability in demanding industrial applications, from packaging machines to robotics. Optimized for Bosch Rexroth drive systems, the MDD090C-N-030-N2L-130PR1 ensures consistent performance, simplified commissioning, and exceptional longevity.

Frequently Asked Questions
How does using “digital servo feedback (DSF)” influence closed-loop accuracy and resonance suppression compared to analog feedback?
DSF feeds back precise digital position and commutation data, enabling tighter loop gains and more accurate trajectory following while letting the drive apply digital filtering to attenuate resonances. It also reduces susceptibility to analog noise and EMI.
What wiring or connector considerations exist for this motor’s connector output and right-side orientation?
Because the connector is on the right when viewed from the shaft end, routing of cables should avoid sharp bends or strain relief near the motor body; shielded multi-core servo cable is mandatory to maintain feedback integrity and prevent interference.
How does the inclusion of a shaft seal and keyway influence the choice of coupling or load interface?
The shaft seal restricts side-loading or misaligned couplings that could wear the seal; use torque couplings or flexible couplings with minimal radial forces and ensure keyway engagement meets DIN depth and clearance tolerances.
What happens during regenerative braking or deceleration: how must the system handle energy returned by this motor?
When slowing or stopping, the motor acts like a generator and pushes energy back to the drive; you must ensure the drive or DC bus can absorb, dissipate, or return this energy (e.g. via braking resistors or regenerative capability).
How should one size the drive’s current and voltage capability for this motor when paired with a digital servo amplifier?
You need a drive whose continuous current rating slightly exceeds what the motor draws at 10.4 Nm, plus headroom for peak current; voltage headroom is also necessary to regenerate during deceleration and maintain control over the full speed range.
