The R911285621 (MDD115D-N-015-N2L-180PB0) is an industrial synchronous motor from Rexroth Indramat, featuring a permanent magnet design with a high torque-to-mass ratio. The motor has a nominal speed of 1500 min⁻¹, continuous torque at standstill of 57.0 Nm, and is configured with a motor length code 'D' and size '115'. It employs digital servo feedback (DSF) for motor feedback and connects via a side B connector. The unit includes a standard housing with a centering diameter of 180 mm, a shaft equipped with a keyway and seal, and standard grease-lubricated ball bearings for extended operational life. The motor does not include a blocking brake and features a standard shaft end without a side B extension.

What mechanical interface advantages come from the 180 mm centering diameter on MDD115D-N-015-N2L-180PB0?

The 180 mm pilot simplifies concentric alignment with gearheads or machine plates for reducing radial runout and coupling stress. It speeds repeatable mounting and helps preserve bearing life under cyclic loads.

Why specify a keyway shaft (with shaft seal) on product code MDD115D-N-015-N2L-180PB0?

Its keyed shaft offers positive mechanical drive without relying solely on friction that is useful for high start/stop duty. Its seal limits ingress of contaminants and helps retain lubrication for protecting front bearings during indexing cycles.

How does “continuous torque at standstill: 57.0 Nm” translate to real applications for MDD115D-N-015-N2L-180PB0?

It indicates the motor can hold or crawl at low speed while delivering 57 Nm continuously within thermal limits. It supports tension control, vertical axes with holding force and precise forming/pressing moves.

What’s the impact of the 1500 min⁻¹ nominal speed on servo sizing for MDD115D-N-015-N2L-180PB0?

The 1500 min⁻¹ base speed balances torque density and usable speed range for easing gear ratio selection. It’s advantageous for medium-speed linearizing actuators, rotary indexers and spindle-like auxiliary motions.

How does the Side-B connector orientation on code MDD115D-N-015-N2L-180PB0 influence cabinet and cable routing?

Its side-B power/feedback exits allow routing away from moving hazards and toward cable chains on many right-hand machine layouts. It can reduce bend-stress, connector strain and electromagnetic coupling with adjacent wiring.
