The synchronous motor R911285980 (MKD112B-048-GP0-LN) is part of the MKD series by Rexroth Bosch Indramat and features a 112 mm frame size with flange size of 192 mm and motor length B. It delivers a continuous standstill torque of 28.0 Nm and supports a rated current of 22.4 A, with maximum current up to 60.8 A. The unit operates in ambient temperatures from 0 to 40°C and employs standard cooling (LN). It includes a keyed shaft (DIN 6885-1) with shaft seal, left-side connection direction, three-phase operation, and IP65 enclosure. Relative position detection is handled by resolver feedback (RSF); the motor is supplied without a holding brake.

How does MKD112B-048-GP0-LN resist unexpected motion during heavy clamping?

It supports 74 Nm max standstill torque. That reserve handles short-duration overloads at zero speed, maintaining fixture position during press cycles, adhesive cures, or tool changes where slip would compromise process accuracy.

What does the current requirement imply for drive sizing on MKD112B-048-GP0-LN?

It draws 22.4 A rated current. This figure guides inverter continuous rating and cable gauge, ensuring thermal limits are respected while preserving dynamic response and keeping voltage drop within acceptable margins across the run.

How do brief accelerations affect electrical provisioning for MKD112B-048-GP0-LN?

It can pull 60.8 A max current. That peak demand informs short-term overload capability in the drive, fuse coordination, and DC bus energy reserves so transient acceleration does not trigger nuisance trips during rapid indexing.

Why does the pilot geometry matter when coupling MKD112B-048-GP0-LN?

It provides a 130 mm centering diameter. The concentric pilot aligns gearheads and pulleys, reducing eccentric load, minimizing vibration at speed, and extending coupling and bearing life in continuous-duty applications.

How does MKD112B-048-GP0-LN simplify cabinet work and service swaps?

It features a power connector. The detachable interface accelerates installation, enables fast replacement, and supports repeatable strain-relief routing, reducing wiring errors and downtime during preventive maintenance or unplanned changeouts.
