Frequently Asked Questions

How does the 57 Nm standstill torque of the MDD115D-N-020-N2L-130PB0 affect machine startup?

It provides high holding capability at zero speed, preventing unwanted motion. This ensures stable positioning during startup and precise control in servo-driven systems.

What installation benefit does the 130 mm centering diameter provide?

The standard diameter allows straightforward alignment with compatible gear units or machine mounts. This reduces installation errors and mechanical stress on couplings.

How does the side B connector orientation influence wiring layout?

A side B connection directs cables away from the drive shaft end, simplifying routing in compact assemblies. It also helps reduce electromagnetic interference by keeping cables clear of moving parts.

How does the 2000 min⁻¹ nominal speed affect its application range?

This speed rating balances torque with dynamic responsiveness, suiting machining, packaging, and automation tasks. It ensures controlled acceleration without excessive overshoot in servo loops.

What advantage does the keyway shaft type provide for torque transfer?

A keyed shaft ensures secure mechanical coupling with hubs or pulleys. This prevents slippage under heavy load conditions common in industrial automation.
