Web1 INTRODUCTION. Permanent magnet synchronous motors (PMSMs) are widely used in the field of electric vehicles (EVs) for their significant advantages, such as high-power density, high-torque density, and high efficiency [1, 2].The vibration and noise problem of the PMSM for EVs has been studied and paid attention to by many scholars, with the … WebAug 22, 2011 · However, electric field noise from the trap electrodes heated up the ions within milliseconds, several orders of magnitude faster than what was expected from Johnson-Nyquist noise [2, 3]. The intensity of this unexpected noise appeared to drop with the ion’s distance d from the metal as 1 / d 4 and the noise appeared to be thermally …
WebThe electric-field noise from the trap depends strongly on the condition of the electrode surfaces. When treated either in situ or ex situ with ion bombardment, significantly lower electric-field noise spectral densities have been reported [18-20]. Moreover, it … WebThat hum we hear is actually a by-product of electricity. It occurs as the alternating current (AC) flows through an appliance or electrical panel, creating varying magnetic fields. …
