MDD115D-N-020-N2L-130GA0

The Bosch Rexroth Indramat MDD115D-N-020-N2L-130GA0 servo motor in the MDD Synchronous Motors series offers a compact, high-performance solution for precision motion control. Featuring Digital servo feedback (DSF) and a robust plain shaft design, this unit delivers a continuous torque at standstill of 57.0 Nm at a nominal speed of 2000 min⁻¹. Manufactured by Bosch Rexroth Indramat, it incorporates low-inertia permanent-magnet technology to ensure rapid acceleration and deceleration. The motor is built without a blocking brake, reducing mechanical complexity while maintaining stable hold. Standard housing and balancing minimize vibration and noise in demanding industrial environments.

The MDD115D-N-020-N2L-130GA0 motor’s critical dimensions and interfaces are precisely defined: it uses a centering diameter of 130 mm, a motor size 115 package, and carries a motor length code D. A shaft seal protects internal bearings from contaminants, and the unit employs a side A connection direction via a robust connector system. The product type is specifically a motor for digital drive controllers, ensuring seamless integration with matching Rexroth Indramat drives. Standardized electrical connections and standard housing balance thermal management with protection against light ingress. The lack of a blocking brake reduces inertia and eliminates brake–control circuitry when static holds are infrequent.

Operational characteristics of the MDD115D-N-020-N2L-130GA0 include a standard balancing rating that limits vibration to acceptable levels at peak speeds, while the shaft type supports direct coupling or non-positive shaft-hub connections. Continuous thermal load is managed through natural convection; the motor withstands repeated duty cycles without active cooling, provided ambient conditions remain within specified limits. A relative encoder embedded within the DSF feedback system eliminates homing routines at startup and ensures reliable position readback. The unit’s laminated core, populated with high-energy magnets, maintains magnetic flux density under thermal stress. During storage and transport, the motor must be secured against tipping and loading to preserve bearing integrity.

System integration is simplified through compliance with Bosch Rexroth Indramat control protocols and digital drive interfaces. The MDD115D-N-020-N2L-130GA0 is ideal for CNC machining centers, robotic actuation, and automated assembly lines requiring precise motion profiles. Its design supports environments with moderate dust and moisture exposure, thanks to its sealed shaft and robust housing. Packaged with durable materials and a one-year warranty, this series motor offers reliable long-term service in industrial automation applications.
