Frequently Asked Questions

How does the plain shaft design of the MDD115D-N-020-N2M-130GA0 affect coupling choices?

The plain shaft requires external coupling elements such as keyless clamping hubs. This allows for flexible integration with driven machine components but demands precise alignment during installation.

What is the role of the multiturn absolute encoder in this motor?

It records shaft position over multiple revolutions without external batteries. This eliminates homing runs, improving start-up efficiency in automation systems.

What installation precautions are necessary with the 130 mm centering diameter?

Accurate centering ensures minimal vibration and balanced rotation. Misalignment at installation can increase bearing stress and reduce accuracy.

How does continuous torque at standstill impact machine performance?

It defines the motor’s ability to provide constant force without rotation. This is crucial for presses, clamps, or index tables requiring holding torque under load.

For the MDD115D-N-020-N2M-130GA0, what does motor length code “D” imply during selection?

The “D” length code corresponds to a higher torque capacity compared to shorter variants. Designers must allocate sufficient mounting space to accommodate its extended housing.
