The R911257394 (MDD112D-N-030-N2M-130GB0) is a digital AC servomotor engineered for applications that demand precise synchronization, such as grinding machinery. It incorporates an integrated temperature sensor for overheating protection and utilizes a floating bearing on side A with a fixed bearing on side B to control radial and axial forces. The motor is equipped with a plain shaft, standard housing, and a shaft seal. Electrical connection is achieved through a side B connector, and the feedback system includes a digital servo feedback (DSF) mechanism with an integrated multiturn absolute encoder, providing a system accuracy of ±0.5 angular minutes. The motor supports a continuous torque at standstill of 38.0 Nm, a nominal speed of 3000 min⁻¹, a continuous current of 60.6A, a torque constant of 0.63 Nm/A, and a maximum torque of 130.2 Nm. The centering diameter measures 130 mm and the motor length code is D. It does not feature a holding brake or a shaft end on side B. The recommended storage and transport temperature range is -20°C to +80°C.

Frequently Asked Questions

How is balancing standard defined in the Bosch Rexroth Indramat MDD112D-N-030-N2M-130GB0 motor design?

The balancing standard refers to rotor alignment reducing vibration during high-speed rotation, protecting bearings and improving mechanical stability across the service life.

How does the motor length code D affect the Bosch Rexroth Indramat MDD112D-N-030-N2M-130GB0 motor characteristics?

The length code determines winding configuration and torque density, balancing size with output power, influencing installation envelope and application suitability.

What implications does the nominal speed of 3000 min⁻¹ have on the Bosch Rexroth Indramat MDD112D-N-030-N2M-130GB0 motor?

The nominal speed defines continuous operational velocity at rated load, offering compatibility with high-speed automation tasks requiring smooth torque delivery.

Does the Bosch Rexroth Indramat MDD112D-N-030-N2M-130GB0 motor require lubrication service for the shaft seal?

Yes, periodic lubrication around the shaft seal enhances seal life and prevents frictional wear during long operational cycles in industrial conditions.

What mounting precision is achieved with the Bosch Rexroth Indramat MDD112D-N-030-N2M-130GB0 motor’s centering diameter?

The 130 mm centering guarantees less than micrometer-level runout, ensuring coupling balance with precision machine shafts under high torque loads.
