Frequently Asked Questions

Why is a 70 Nm holding brake essential for load safety?

The holding brake locks the shaft during power loss preventing unwanted motion. The feature secures vertical or suspended loads safely.

How does continuous torque at standstill influence precision tasks?

The constant torque output keeps position fixed without drift under load. The stability benefits machining and pick-and-place applications.

What role does a keyed and sealed shaft play in motor reliability?

The keyed design ensures firm coupling between motor and load under torque stress. The sealing prevents dust and fluid contamination of internal parts.

How does a 180 mm centering diameter enhance motor alignment?

The centering diameter provides strong support for balanced mounting. The alignment reduces vibration and mechanical wear during rotation.

Why is a side B power connector layout beneficial in machinery design?

The side connector simplifies wiring inside control cabinets. The layout saves space and improves accessibility during installation.
