MDD090A-N-020-N2M-130PL2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-020-N2M-130PL2 is a high-performance motor in the MDD Synchronous Motors series, designed for precision motion control in modern automation systems. As a Motor for digital drive controllers, it features an integrated multiturn absolute encoder and digital servo feedback (DSF) for unrivaled positioning accuracy. With a continuous torque at standstill of 3.7 Nm and a robust holding brake torque of 11.0 Nm, this motor ensures stable, secure holding and controlled acceleration under varying load conditions.
This motor’s technical profile underscores its adaptability and mechanical integrity. The motor size (090) and centering diameter of 130 mm provide a compact footprint while guaranteeing rigid mounting and alignment. It operates at a nominal speed of 2000 min⁻¹, delivering rapid response and smooth operation. The standard housing encloses precision-wound windings and bearings, while the shaft type keyway and shaft seal protect against contamination and wear. The motor length code A denotes a balanced design optimized for torque-to-inertia ratio, and the standard (without side B shaft end) configuration simplifies installation.
Additional features highlight the motor’s durability and ease of integration. The inclusion of a blocking brake ensures reliable holding even when powered down, and the left connection direction with a standardized connector interface simplifies cabling and service. Rated for industrial environments, the standard balancing maintains smooth rotation at high speeds, reducing vibration and noise. The MDD090A-N-020-N2M-130PL2 meets stringent reliability standards, offering maintenance-free operation and long service life. In industrial applications, it delivers precise positioning, efficient energy use, and enhanced operational safety, making it an ideal choice for advanced manufacturing and automation systems.

Frequently Asked Questions
What does the "multiturn absolute encoder with digital servo feedback (DSF)" mean for homing and position loss recovery?
Because the encoder retains absolute position over power cycles, the system does not need to recalibrate or find a home-position on restart, reducing downtime and increasing reliability; DSF also gives precise, high-resolution feedback, which improves closed-loop error correction.
How critical is the 3.7 Nm continuous torque at standstill for designing the drive sizing and thermal performance?
This torque rating at zero speed puts demands on current handling and heat dissipation during holding or low-speed conditions; sustained high torque at standstill will raise winding temperature significantly, so cooling and duty cycle must be considered.
How does the holding brake torque of 11.0 Nm interact with safety and mechanical load-holding in industrial setups?
The brake ensures the load remains static when power is removed or during power interruptions, which is essential for vertical axis, safety locks or when emergency stops are triggered; its rated torque must exceed the gravitational or spring forces acting on the load to prevent slippage.
What installation alignment concerns arise from the centering diameter of 130 mm and keyway shaft?
A larger centering diameter gives a stiffer mounting interface reducing run-out and misalignment; the keyway ensures torque transmission but requires correct dimensioning and fit to avoid creating stress concentrations that degrade bearings..
At nominal speed of 2000 min⁻¹, what limits does inertia impose on acceleration and system responsiveness?
Rotor and attached load inertia relative to motor torque determine how quickly the motor can accelerate/decelerate; high inertia loads will slow response, require higher currents, and cause overshoot unless drive tuning (e.g. servo gains) is optimized
