Variable flux motor energy storage

What are variable flux memory Motors (vfmms)?

Abstract: Variable flux memory motors (VFMMs) are a relatively new class of machine that affords one the ability to actively change a motor from a high torque/low speed device into a low torque/high speed device through the online control. With regard to the method of controlling flux, VFMMs are categorized in this paper.

What is a variable-flux flux intensifying machine (VFM)?

The Variable-Flux Flux Intensifying machines are found to be the state-of-the-art VFM technology available to-date. The paper also reviews the magnetization process in VFMs and relates this with the B-H curve of the magnetic material. The conventional PM machine mathematical model is adapted to represent the operation of VFMs.

Does a VFM have a flux adjusting mechanism?

Therefore, novel topologies and flux-adjusting mechanisms of the VFM have been proposed in recent years, and the VFM not only has the advantages of the traditional permanent magnet (PM) motor but also can effectively adjust its internal magnetic field [6, 7].

Do variable-flux machines offer new opportunities for improved machine design?

Modern applications demand challenging operation requirements from electrical machines. Variable-flux machine (VFM) concepts are found to offer new opportunities for improved machine design. This paper reviews the VFM technology.

What are mechanical-variable-flux PM machines?

Compared with electrical variable flux techniques, the mechanical-variable-flux PM machines (MVF-PMMs), which can adjust flux effectively and conveniently, are presented and studied.

Does MVF-IPM machine have a higher flux-weakening capability?

It can be seen that the MVF-IPM machine has a higher flux-weakening capability than the conventional machine regardless of states. Table 4. Comparison of flux-weakening capabilities in the conventional and MVF-IPM machines The corresponding efficiency maps are shown in Fig. 13, where the maximum torque per ampere (MTPA) control strategy is adopted.
