Why would you choose a sealed plain shaft instead of a keyed or splined one?

A sealed plain shaft minimizes contamination risk and wear in environments with dust or coolant. It's ideal where smooth coupling and maintenance simplicity are priorities.

Does the MHD090B-047-PG1-UN require an external encoder for position tracking?

No, it has an integrated encoder with absolute position detection. This simplifies setup and avoids encoder alignment or external wiring.

How does the integrated feedback system improve motion control precision?

It provides high-resolution, multi-turn absolute feedback directly from the motor. This ensures accurate positioning and smooth interpolation, especially in complex motion profiles.

What does a continuous standstill torque of 12 Nm imply in a real-world application?

It means the motor can hold or resist mechanical loads of up to 12 Nm indefinitely without overheating. This is critical for applications like vertical axes or static clamping systems.

Can the MHD090B-047-PG1-UN be used in space-constrained control cabinets?

Yes, its compact motor length and integrated connectors reduce footprint. This makes it suitable for tightly packed or modular machines.
