The R911263266 (MDD115A-N-030-N2M-130PB1) is a Bosch Rexroth digital AC motor designed for use with digital drive controllers. It features a continuous standstill torque of 28.0 Nm, nominal speed of 3000 min⁻¹, and housing with a centering diameter of 130 mm. The unit integrates a multiturn absolute encoder with digital servo feedback (DSF) for precise position detection. Its blocked brake provides 45.0 Nm holding torque, with 18 ms clamping and 55 ms release delays. The shaft features a keyway and is sealed, with connections on Side B via connector. Standard balancing and bearings permit both radial and axial load support. Housing and shaft end conform to standard specifications.

Frequently Asked Questions

How does the 90-minute thermal time constant affect operation?

It means the motor can withstand extended periods of high load before reaching thermal limits. This allows for predictable performance in duty cycles with variable torque demands.

What role does the integrated multiturn absolute encoder play?

It retains position data across power cycles, eliminating the need for homing. This improves startup times and reduces system downtime.

What torque stability is achieved with 28 Nm at standstill?

It ensures reliable holding and positioning without overheating under continuous stall load. This supports precision machining or clamping functions.

Why does the MDD115A-N-030-N2M-130PB1 use digital servo feedback instead of analog?

Digital feedback provides higher resolution and reduced signal noise. This translates to smoother motion and tighter control loops.

What is the advantage of using a keyway shaft design?

It provides a secure, slip-free connection between the motor and coupling elements. This is critical for transmitting torque under dynamic loads.
