Frequently Asked Questions

How does the holding brake of the MDD115A-F-015-R2L-180GA2 affect machine safety?

The brake ensures the motor shaft remains fixed when power is off, preventing load drift. This is critical in vertical or suspended axis applications.

Why is digital servo feedback (DSF) important in this motor?

DSF provides high-resolution positional data, enabling precise control in closed-loop systems. This minimizes errors in applications requiring repeatability.

What installation factor should be considered with a 180 mm centering diameter?

The centering diameter must match the machine’s mounting interface to ensure alignment. Improper fit can cause vibration and reduce bearing life.

Does the plain shaft design limit coupling options?

A plain shaft requires external keying or clamping devices for torque transfer. This provides flexibility but demands proper coupling alignment.

How does continuous torque at standstill impact performance?

It allows the motor to hold heavy loads without overheating. This is useful in applications like presses or clamping systems.
