Memory machines (MMs) equipped with hybrid permanent magnets (PMs), i.e., NdFeB and low coercive force (LCF) PMs, combine the merits of acceptable torque capability at low speeds and efficiency improvement at high speeds. Meanwhile, the PM flux linkage can be flexibly adjusted with the aid of current pulses, which is desirable for variable speed applications. To effectively extend the constant power...
A novel switched-flux (SF) surface-mounted permanent magnet (PM) memory machine is proposed by incorporating the flux-memorizable concept into the SF structure. It employs a temporary current pulse to magnetize/demagnetize the aluminum–nickel–cobalt (Al–Ni–Co) PMs so that the air-gap flux can be regulated online for extending its high-speed constant-power region. An analytical hysteresis modeling...
