MDD093D-N-040-N2L-110GR2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2L-110GR2 motor from the MDD Synchronous Motors series is engineered for precise, high-speed applications and meets strict industrial requirements. This product type: Motor for digital drive controllers features a robust motor size 093 frame and a motor length code D to balance torque density with spatial constraints. Integrated digital servo feedback (DSF) ensures accurate position and speed control, while standard balancing minimizes vibration across the operating range. The combination of a plain shaft and a with shaft seal design delivers reliable torque transfer and long-term durability.
With a continuous torque at standstill of 24.0 Nm and a holding brake torque of 22 Nm, this motor maintains position securely under load, supported by an integrated blocking brake. The centering diameter of 110 mm and standard housing provide compatibility with a wide range of mounting interfaces, simplifying installation. Designed for a nominal speed of 4000 min⁻¹, the motor sustains high-performance operation throughout demanding duty cycles. A right-handed connector style connection direction streamlines cabling and reduces setup time in cabinet layouts.
Built to integrate seamlessly with Bosch Rexroth’s digital drive controllers, the MDD093D-N-040-N2L-110GR2 is ideal for precision motion systems in packaging, textiles, and robotics. Its standard (without side B shaft end) configuration minimizes ancillary components while preserving flexibility for custom attachments. The combination of proven servo feedback, secure braking, and compact dimensions makes this synchronous motor a dependable choice for automated processes requiring both speed and accuracy.

Frequently Asked Questions
With the blocking brake rated at 22 Nm, how should I size it relative to external loads?
The brake must exceed the external load’s holding torque (plus a safety margin) to reliably hold position. In high-dynamics systems, assume friction, wear, or shock loads and size the brake 20–30 % above nominal load.
What are the implications of the plain shaft + shaft seal design in industrial environments?
The plain shaft (no keyway) reduces stress concentrations and eases coupling design, while the shaft seal protects internal bearings and winding insulation from contaminants. In dusty or wet settings, the seal helps maintain longevity but must be compatible with the fluid/particle types in the environment.
Why is standard balancing important for this motor in high-speed systems?
Standard balancing reduces rotor eccentricity and lowers vibration, which is essential at 4000 rpm to avoid bearing fatigue and resonance excitation. In ultra-precision systems, you may request higher-grade (class R) balancing for even lower vibration.
In a robotics or packaging line scenario, how does this motor improve throughput or precision?
It supports high-speed, rapid directional changes with tight positioning, thus shortening cycle times and improving repeatability. The strong holding torque and brake allow the robot or conveyor to hold position reliably during transitions or power disruptions.
What are the failure modes or maintenance considerations for the Bosch Rexroth Indramat MDD093D-N-040-N2L-110GR2 motor?
Wear of bearings, degradation of the internal feedback encoder, or brake wear are primary failure points; scheduled vibration checks and encoder calibration mitigate surprises. Also, exposure to overcurrent, overheating, or misalignment are common causes of insulation or rotor damage.
