The benefits of using magnetic bearings are clear to see:
- Oil-free
- Wear-free
- Maintenance-free
The shaft rotates permanently around its centre of gravity, making it vibration-free. As it remains free from any physical contact, no lubrication is required.
Even frequent start-stop processes are completely wear-free. During shutdown, the shaft is brought to a standstill within the magnetic field. In the unlikely event of a failure of the magnetic bearing controller, the safety bearings will bring the shaft gently to a halt.
The drive motor is airtight, so it cannot be contaminated by the ambient air – substantially increasing the turbo blower’s operational reliability, availability and service life.
