6 FAQs about [Mechanical energy storage magnetic levitation]

What is a magnetic levitation system?

Modelling of magnetic levitation system The magnetic levitation system, including an axial suspension unit and a radial suspension unit, is the core part of suspending the FW rotor to avoid friction at high rotating speed, and then the storage efficiency of the MS-FESS is further improved by reducing the maintenance loss.

How can magnetic levitation improve the rotational speed and reduce maintenance loss?

To improve the rotational speed and reduce maintenance loss, magnetic levitation technology is utilized to actively regulate the displacements of the FW rotor in the FESS, considering the benefits of zero contact [23, 24] and active controllability [25, 26].

Can magnetic forces stably levitate a flywheel rotor?

Moreover, the force modeling of the magnetic levitation system, including the axial thrust-force permanent magnet bearing (PMB) and the active magnetic bearing (AMB), is conducted, and results indicate that the magnetic forces could stably levitate the flywheel (FW) rotor.

Can a magnetic levitation system levitate a Fw rotor?

Moreover, the magnetic levitation system, including an axial thrust-force PMB, an axial AMB, and two radial AMB units, could levitate the FW rotor to avoid friction, so the maintenance loss and the vibration displacement of the FW rotor are both mitigated.

What if FF is regarded as zero after applying magnetic levitation?

After applying magnetic levitation in axial direction, the friction is very small and Ff can hence be ignored. There is no applied mechanical load for the FESS, Tm is thus regarded to be zero. In this case, (28) can be rewritten as (30) d ϖ r dt = 1 J T e = K T J i cq When the machine is in generation mode, Te is negative.

Can a compact magnetic bearing eliminate friction loss during high-speed operation?

A novel compact magnetic bearing is proposed to eliminate the friction loss during high-speed operation. First, the structure and working principle of the flywheel energy storage system are described in detail. Then, the topology of the magnetic bearing is introduced, and its magnetic circuit model is built and analyzed.
