MDD093A-N-020-N2L-110GA1

The Bosch Rexroth Indramat MDD093A-N-020-N2L-110GA1 servo motor in the MDD Synchronous Motors series delivers a high-density digital AC drive solution engineered for precision automation. Featuring a plain output shaft with shaft seal and an integrated blocking brake, this unit is optimized for dynamic tool-changing applications. The maintenance-free design incorporates digital servo feedback to monitor rotor position with high resolution, ensuring consistent contour accuracy and repeatability. Engineered for simple installation and rapid commissioning, the MDD093A-N-020-N2L-110GA1 supports demanding duty cycles without fluid accumulation around the output shaft when mounted per IM V3 specifications. This robust package combines high torque density and reliable brake functionality, making it suitable for modern manufacturing environments.

Detailed technical specifications define the MDD093A-N-020-N2L-110GA1 as a compact, high-performance unit. The motor operates at a Nominal Speed of 2000 min⁻¹ and features a Motor Size of 093 with a Centering Diameter of 110 mm for flange mounting. Its Mass of 13 kg provides an optimal power-to-weight ratio for portable or movable axes. Feedback is handled via Digital servo feedback (DSF) through a standard Connector interface, while the motor’s Standard balancing and Standard housing comply with DIN 40 050. Thermal constraints are defined by a Maximum Transport and Storage Temperature of 80°C, and the cooling system employs Surface Cooling, Natural Convection aided by a Radial blower. Brake dynamics include a Clamping Delay of Blocking Brake at 20 ms and a Release Delay of Blocking Brake at 60 ms, delivering a Holding Brake Torque of 11 Nm under all operating conditions.

Operational features emphasize durability, environmental resistance, and performance stability. The MDD093A-N-020-N2L-110GA1 achieves an IP65 protection rating for both shaft seal and overall housing, preventing ingress of dust and liquids. Its brushless design and lifetime-lubricated bearings support radial and axial load handling with minimal maintenance. Direct attachment of belt pulleys or pinions is facilitated by the plain shaft end, eliminating coupling components and reducing backlash. High contouring accuracy is sustained across temperature ranges up to 55°C, while the integrated radial blower ensures effective surface cooling during extended duty cycles. Permanent magnets of iron oxide or rare-earth composition provide consistent torque delivery under variable load profiles.

System integration is streamlined for compatibility with digital drive controllers and conventional servo amplifiers, supporting real-time feedback loops and advanced motion algorithms. The unit’s mounting flange with a 110 mm centering diameter adheres to standard machine interfaces, enabling plug-and-play replacement and modular machine designs. Typical applications include tool-changing spindles, pick-and-place modules, CNC axes, and robotic end-of-arm tooling where high power density, precision positioning, and reliable braking are critical. The MDD093A-N-020-N2L-110GA1 is ideally suited for packaging machinery, assembly lines, and high-speed automation cells requiring robust, maintenance-free performance.
