Frequently Asked Questions

Why is the 130 mm centering diameter relevant to mounting precision and shaft alignment?

The pilot (centering) diameter references the motor to the machine face for minimizing radial runout before coupling engagement. It reduces bearing loads and improves dynamic accuracy at the coupling interface.

How does the 1500 min⁻¹ nominal speed of MDD115D-F-015-N2M-130GB0 affect mechanism selection?

This base speed pairs well with moderate gear reductions for balancing torque multiplication and servo bandwidth for pick-and-place, feeders and roll-drives. It simplifies matching to standard digital drive controllers in multi-axis systems.

What practical implications arise from the motor’s 57.0 Nm continuous torque at standstill (MDD115D-F-015-N2M-130GB0)?

It enables sustained low-speed force for tensioning, indexing or holding loads during process pauses without thermal overload. Its integrators can size gear ratios for constant torque regions for improving process stability in packaging and printing lines.

How does “plain shaft with shaft seal” on MDD115D-F-015-N2M-130GB0 influence coupling and contamination control?

It supports backlash-free collet/clamp couplings and easy removal for service. Its shaft seal limits ingress at the bearing zone for protecting lubrication and extending service intervals in dusty converting or textile cells.

What benefits does Digital Servo Feedback (DSF) provide compared with analog tachometer/Resolver schemes?

It carries high-resolution position and speed digitally for improving noise immunity and parameter observability for modern drives. It streamlines cabling/connectors and supports multi-turn absolute data for deterministic restarts.

Internal Product Review

Bosch designs the servo motor MDD115D-F-015-N2M-130GB0 with side B connector and a plain sealed shaft to attain IP65 protective rating. It integrated DSF and a multiturn absolute encoder. This unit is built to deliver 57 Nm torque at standstill and it comes in standard housing with 130-mm centering. It omits blocking brake and fits into industrial machines such as textiles and tooling.
