Qnetic Frictionless Tech
In reality, losses from friction, air resistance, and vibration are inevitable. But they can be engineered down to near-zero. One of Qnetic's core technologies enabling this is the Active Magnetic Bearing (AMB).
“If it’s spinning at high speed… doesn’t it have high friction-losses?”
In reality, losses from friction, air resistance, and vibration are inevitable.
But they can be engineered down to near-zero.
One of Qnetic’s core technologies enabling this is Active Magnetic Bearing (AMB):
- We custom-designed it with a specialist partner
- Its performance was verified through vigorous testing
- The first units have arrived and are ready for integration into our alpha prototype
So what is an Active Magnetic Bearing?
At a high level, it is a frictionless support system for a high-speed rotating shaft with:
- Multiple pairs of electromagnets arranged around the shaft with a micron-scale gap
- Sensors continuously measuring shaft position relative to each magnet
- A digital controller adjusting thousands of times per second
- Power electronics dynamically tuning magnetic forces to keep the shaft perfectly centered
The system actively stabilizes the shaft in real time, without any physical contact.
In short:
- No contact means no mechanical wear over time
- No friction results in minimal energy loss
- Real-time control enables extreme precision and stability
This is not commodity engineering. It is a deep-tech capability.
The same control architecture applies to industries where precision defines value, including:
- Semiconductor manufacturing
- Space and defense systems
- Advanced medical devices
Only a small number of companies globally can design and integrate systems at this level for high-speed, grid-scale applications.
This is what enables Qnetic to deliver long-duration, high-speed energy storage with consistent performance over time.
