MDD090C-N-030-N2L-110PR2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090C-N-030-N2L-110PR2 from the MDD Synchronous Motors series is a high-performance Motor for digital drive controllers engineered for precision motion applications. This unit features a compact Motor Size 090 frame with a Motor Length Code C and a robust Centering Diameter of 110 mm to ensure accurate alignment and rigidity. Equipped with a Digital servo feedback (DSF) system, it provides real-time commutation, rotor position, and speed control at a Nominal Speed of 3000 min⁻¹. An integrated blocking brake delivers a Holding Brake Torque of 11.0 Nm, holding loads safely when de-energized.
Reliability and durability are built in, starting with a Standard balancing procedure that minimizes vibration and noise. The Housing Standard enclosure supports a Shaft Seal to protect internal components from contamination and extends service life. A precision-cut shaft keyway per DIN 6885 sh.1, 8-68 Edition ensures secure coupling, while the Connection Type Connector and Connection Direction Right configuration simplify field wiring. At standstill, the motor maintains a Continuous Torque at Standstill of 10.4 Nm and delivers consistent performance under dynamic loads.
This permanent-magnet servo motor incorporates an encoder for seamless digital feedback and is supplied as a turn-key solution for Rexroth Indramat drive systems. Its Shaft End Standard (without side B shaft end) design and plug-and-play connectivity accelerate installation, reduce commissioning time, and support a wide range of automation tasks. Ideal for packaging machines, gantry robots, and NC tools, the MDD090C-N-030-N2L-110PR2 sets a benchmark for precision in modern automated processes.

Frequently Asked Questions
How does the continuous torque at standstill of 10.4 Nm influence gear selection or load holding for automation equipment?
Standstill torque means the motor can hold a static load without motion under that torque; if your load produces more torque (moment) at stall, you’ll need gearing or mechanical advantage. For example, without gearbox, any external torque above ≈10.4 Nm will cause drift or require the holding brake.
How does the standard shaft seal improve motor longevity in industrial environments?
A shaft seal helps protect internal parts (bearings, windings) from ingress of dust, coolant, or oils, which are common in packaging or CNC environments. That means fewer maintenance intervals and lower risk of premature failures due to contamination.
What considerations arise from the nominal speed of 3000 min⁻¹ when driving high-inertia loads?
At high speeds, torque drops due to limitations in current and cooling; high inertia loads may require higher torque during acceleration and deceleration phases. Also, resonance and dynamic stiffness become more critical; mounts, damping, and control loop bandwidth need to be designed accordingly.
What are the benefits and constraints of the product’s standard housing in terms of cooling and thermal management?
Standard housing typically relies on natural convection or surface cooling; ambient temperature rises and duty cycle must be limited to avoid overheating. If continuous high load at high speed is expected, auxiliary cooling or derating may be necessary.
In B2B applications, how might this motor reduce system complexity compared to using separate motor + brake + encoder assemblies?
By integrating servo feedback and an internal brake, it reduces the number of components, connectors, and alignment steps, cutting cable routing and mechanical assembly. This translates into lower installation cost, fewer failure points, and easier maintenance or replacements in industrial setups.
