Abstract
- The dual-memory machine utilizes two kinds of permanent magnets (PMs), namely the aluminum-nickel-cobalt (Al-Ni-Co) and neodymium-iron-boron (Nd-Fe-B) materials, to provide effective flux-mnemonic feature. Namely, the Al-Ni-Co PM can be forward or backward magnetized in such a way that it can coordinate with the Nd-Fe-B PM to online tune the air-gap flux density. Based on the proposed DC-excited memory machine structure, the magnet proportioning between the Al-Ni-Co PM and the Nd-Fe-B PM is analysed. Both simulation and experimentation are carried out to verify the validity of the proposed dual-memory machine design. [ABSTRACT FROM PUBLISHER]
