The R911270311 (MDD115D-N-020-N2M-130PA2) is a digital AC servo motor from the Bosch Rexroth MDD series, designed for integration with digital drive controllers. It features a nominal speed of 2000 min⁻¹, a 130 mm centering diameter, and achieves a continuous torque at standstill of 57.0 Nm. The rotor design employs rare-earth or iron oxide magnets, and the motor includes a shaft with a keyway and shaft seal. It is equipped with an integrated multiturn absolute encoder for position feedback and uses digital servo feedback (DSF). The motor is built with a standard sealed housing and is balanced to class N (DIN VDE 0530). The holding brake provides 60.0 Nm of torque. Connection is via a side A connector; the shaft end is standard with no side B extension.

Frequently Asked Questions

What installation considerations apply to the MDD115D-N-020-N2M-130PA2 motor’s 130 mm centering diameter?

The larger centering diameter provides mechanical stability for high-torque applications. Installers must ensure compatible mounting surfaces to maintain alignment and reduce vibration.

Why is digital servo feedback (DSF) important in synchronous motor control?

DSF improves closed-loop precision by delivering high-resolution position and speed data. This ensures smoother motion profiles and better responsiveness in demanding tasks.

What torque stability benefits does 57 Nm continuous torque at standstill provide?

It allows the motor to maintain force without rotation, supporting heavy loads in static positions. This is particularly valuable in clamping, pressing, or holding operations.

Can the MDD115D-N-020-N2M-130PA2 be used in packaging lines?

Yes, its precise control and nominal 2000 min⁻¹ speed are suitable for synchronized conveyor and sealing operations. It supports continuous, repeatable movements required in packaging cycles.

How does the MDD115D-N-020-N2M-130PA2 support robotics applications?

Its precise feedback and torque control enable accurate joint movement and repeatable positioning. This makes it suitable for robotic arms requiring high accuracy and endurance.
