The MPN R911269556 (MDD115A-N-030-N2M-130GA1) is a Bosch Rexroth AC servo motor designed for high-torque applications and precise motion control. It features a brushless construction, integrated multiturn absolute encoder, and digital servo feedback (DSF) for real-time position and speed monitoring. The unit incorporates a built-in temperature sensor, standard housing, and grease-lubricated bearings. Key parameters include a nominal speed of 3000 min⁻¹, maximum torque of 87.1 Nm, continuous standstill torque of 28.0 Nm, and 45.0 Nm holding brake torque. The centering diameter is 130 mm, the motor size is 115, and a plain shaft with shaft seal is fitted. The encoder system ensures high accuracy for digital drive controllers, and the unit conforms to DIN 40500 protection standards against water, foreign objects, and high voltage. Connection is via a connector on Side A, and the design omits a shaft end on side B.

Frequently Asked Questions

How does the multiturn encoder in the MDD115A-N-030-N2M-130GA1 improve system accuracy?

It tracks multiple shaft revolutions, allowing precise absolute positioning without homing. This minimizes downtime during restarts and ensures consistent synchronization in automated processes.

Why is a plain shaft configuration advantageous in automation setups?

A plain shaft design allows flexible coupling with various gear units or machine interfaces. This makes integration easier across multiple machine platforms without custom modifications.

Does the MDD115A-N-030-N2M-130GA1 require external feedback devices?

No, its integrated encoder provides servo feedback directly to the controller. This simplifies wiring and reduces the need for additional sensor hardware.

What role does the blocking brake torque of 45 Nm play in safety?

It holds mechanical loads firmly when the motor is not energized. This prevents axis drift in vertical or suspended applications like lifts or gantries.

How does the standard balancing procedure affect performance over time?

It keeps shaft rotation consistent and reduces wear on bearings. This ensures stable motion even in continuous duty cycles.
