Frequently Asked Questions
How does the cooling method influence system design in MKD041B-058-GG1-KN?
The unit employs natural convection cooling, eliminating fans and associated failure points. This approach ensures predictable winding temperatures and simplifies enclosure design in continuous-duty operations.
Which current value determines drive and protection requirements in MKD041B-058-GG1-KN?
The motor offers a 5.2 A nominal current specification serves as the basis for sizing drives and cables, ensuring electrical safety margins remain within design limits during sustained operation.
What is the maximum permissible speed in MKD041B-058-GG1-KN?
The motor achieves up to 4500 RPM, providing agility for rapid motion cycles while maintaining acceptable thermal performance.
How are loads retained during power-off events in MKD041B-058-GG1-KN?
An integrated 2.2 Nm holding brake secures the shaft in a fixed position during shutdowns, enhancing safety for vertical axes and during servicing.
Which stall torque rating supports static phases in MKD041B-058-GG1-KN?
Absolute detection exceeds >4096 revs, preserving multi-turn reference. This continuity reduces homing time.
