Frequently asked questions

What is the advantage of the holding brake in the Siemens 1FK7040-2AK71-1TH0 motor?

The holding brake on the Siemens 1FK7040-2AK71-1TH0 motor provides a mechanical lock to prevent the shaft from rotating when the motor is de-energized. This is crucial for applications that require the load to be held in position, such as on inclines or during power outages.
