Each switch can detect an open-circuit condition and is protected against over-current, over-voltage from demagnetization (inductive kick or flyback voltage) and over-temperature conditions.
Using a smart phone key eliminates problems in the event of key loss or demagnetization of the plastic key card.
The works have approached mainly the detection of open phase fault [1, 7]; stator winding inter-turn short circuit [3, 8, 9]; rotor demagnetization [2, 10]; mechanical misalignment; mechanical unbalance [11]; airgap eccentricity [12, 13]; bearing fault [14]; and motor drive faults [15].
The major concern of losses during IC is the influence of temperature rise on magnet demagnetization.
In the well-known works, for the calculation of the magnetostatic field of the cores the methods of demagnetization coefficients [2, 3] and integral equations [1, 4, 5] are developed.
Electromagnets, superconductor materials more specifically, as well as permanent magnets can be used to achieve the magnetization and demagnetization processes in the magnetic refrigeration cycle.
where [DELTA][H.sub.pp] is the width of the EPR line of the spectrum, [K.sub.1] is the anisotropy, p is the porosity, [H.sub.e] is the noneddy currents, and Hid is the inhomogeneous demagnetization.
RT-SIRM cycles including a thermal demagnetization stage according to [42] allowed us to determine goethite content in the samples and confirmed the goethite content increase between ~0.8 and 2 wt.% (Table 2).
[H.sub.eff] is the total effective field, including Heisenberg exchange, demagnetization, magnetic anisotropy, DMI, and external applied magnetic fields.
On the contrary, the Co phase with a soft magnetism will be first reverse magnetized, ultimately making the adjacent 2:17R more easily demagnetized during demagnetization process, and thus the low [H.sub.c] is inevitable.
Interestingly, artists often deploy analog demagnetization and the artifacts of digital compression as metonymies for the struggle to regain effaced histories and distorted historical knowledge (Marks, 2015, chapter 8).
1 and described as following; (a) magnetization: the magnetic field strength is increased causing magnetic entropy to decrease which further increases MCM's temperature; (b) cold blow: some heat transfer fluid is employed to absorb MCM heat to cool it down to ambient temperature; (c) demagnetization: the magnetic field intensity is decreased causing magnetic entropy to increase which further lowers MCM's temperature; (d) hot blow: again a heat transfer fluid is used to reject the heat to MCM increasing its temperature and thus the cycle goes on.
