Abstract

Canned Permanent Magnet Synchronous Motors (CPMSMs) are essential components in vacuum pump systems. The stator can of CPMSMs is susceptible to deformation due to thermal stress and high-frequency harmonic electromagnetic force, leading to potential failure. When the CPMSMs are powered by an inverter power supply, it introduces time harmonic current, exacerbating the thermal stress and harmonic electromagnetic force of the system. Thus, this paper analyzes the effects of low-order current harmonics on the electromagnetic force and forced vibration of the stator can. The analytical formulation for the radial electromagnetic force of the CPMSM is obtained, taking into account the influence of harmonic current. Afterwards, the finite element model was established to investigate the space and time harmonic characteristics of the magnetic field and electromagnetic force of the stator can, and its validity was confirmed through testing on a motor test platform. Finally, modal analysis of the stator can under rated conditions and investigation of mechanical deformation induced by electromagnetic force are carried out through harmonic response analysis. This establishes a theoretical basis for improving the reliability and sealing performance of CPMSMs used in pumps.

Abstract

Unmanned Aerial Vehicle (UAV) frequently encounter various external disturbances during flight. After experiencing such disturbances, the UAV’s power supply must quickly respond and maintain stable output. To address this problem, this paper proposes an improved active disturbance rejection control (IADRC) scheme combined with peak current mode control (PCMC) based on a six-phase interleaved parallel synchronous buck converter. Modal analysis was conducted on the synchronous buck converter, and small-signal modeling was performed under current control mode to analyze closed-loop stability. The dynamic response speed was improved by utilizing a peak current inner loop, enabling precise current sharing. The system’s disturbance rejection capability was enhanced by employing an improved extended state observer for real-time estimation of disturbances. This approach offers advantages such as high dynamics, strong disturbance rejection, and good current sharing. Finally, an experimental prototype with a rated power of 1000 W, maximum efficiency of 96.9%, and power density of 12.9 W/cm2 was constructed. Comparing three different control schemes, the response waveforms of the prototype verify the feasibility and advancement of the scheme in this paper.

Abstract

The real-time management of the Production-Transport-Consumption system reveals the need for information on the state of the network and the means of action on it at all times. This need is met through the use of telecontrol systems. These operate mainly on substations, complex installations that ensure the interconnection of lines and the transformation of voltage levels. In this work, we are interested in the propagation of Power Line Carrier (PLC) communication technology in power cables, both on a single cable and on a Y topology. We will analyze respectively the effect and the influence of several factors on the transfer function such as: effect of the end loads, the length of cable, the junction between two sections of cables in order to deduce the frequency channel of most favorable transmission. The results of the transfer function predictions obtained by the analytical formulation are compared and validated with full-field simulations using the CST software.

Abstract

Brushless DC motors (BLDC) present several technical advantages with respect to conventional permanent magnets synchronous motors. These advantages include higher rotational speeds, reduced construction complexity and simpler control strategies. This paper discusses a cost-effective control strategy for BLDC motors characterized by low stator inductance. The proposed technique is based on an LC filter inserted between the inverter output and the motor. The filter capacitors are controlled such that three DC voltages are applied to the stator terminals. An active damping approach is used to control stator currents and prevents voltage oscillations. Compared with existing solutions, this technique simplifies the hardware implementation of such a drive system and offers a notable reduction in the switching frequency with minimal values of the magnetic elements. In addition, high frequency torque ripples are significantly reduced. The design procedure of this controller is presented in this paper and the performances are compared with the conventional control technique.

Abstract

This paper proposes a novel improved hybrid permanent magnet Vernier machine (IHPMVM), which is characterized by less-rare-earth (LRE) and high torque-density. The proposed machine features a hybrid magnet arrangement, which adopts both rare earth (RE) and LRE magnets in one magnetic pole simultaneously. The proposed improved design can reduce the consumptions of RE materials by employing low-cost LRE magnets in place of RE magnets. Besides, the hybrid magnet arrangement design has a good magnetic flux-concentrated effect, resulting in high torque density. Particularly, dummy slots are introduced to achieve a flux modulation effect. This unique design effectively reduces the inevitable leakage flux, thereby further improving the utilization of PMs and torque density. Firstly, the machine configuration and its improved design are introduced and investigated. Then, a multi-objective optimization is carried out to obtain the optimal design of the proposed machine considering comprehensive performance. Furthermore, the preliminary electromagnetic characteristics of the proposed machine are compared and analyzed using finite element (FE) methods, which verifies the effectiveness of the optimization. Finally, the demagnetization risk of the LRE magnets is evaluated. This paper is expected to provide a technical reference for designing LRE machines.

The pages must be numbered consecutively. Articles should be divided into numbered sections, and if necessary subsections, preferably: Introduction, Material, Methods, Results, Conclusion and References. Any special characters (e.g. Greek, script, etc.) should be named in the margin where the character first occurs in the text. Names of species are to be accentuated with wavy underlining (italics). Equations should be numbered serially (1), (2), ... on the right side of the page. Footnotes should be avoided, if required, they should be used only for brief notes which do not fit well into the text. Figures and tables have to be included into the text. If table is typed on a separate page its position in the text should be marked. Abbreviations should be explained when they first appear in the text.

Math:

Please use the MathML editor as well as MathType editor to build an equation in your manuscript.

Equations:

Equations should be typed within the text, centred, and should be numbered consecutively throughout the text. Their numbers should be typed in parentheses, flush right. Equations should be referred to in text, e.g. (1), except at the beginning of a sentence: "Equation (1) is ...". All symbols appearing in equations have to be defined in the text, before or just after the equation.

If the symbols are written in Times New Roman use italic fonts. Symbols of vectors and matrices should be written in bold fonts. Do not italicize Greek fonts and mathematical symbols like e.g.: the derivative symbol d, max, min, etc. The indices of symbols that are indices themselves should be written in a clear manner.

Note that the equation is centered using a center tab stop. Please keep the same font in the formulas and text.

Unit Symbols, Abbreviations:

Define abbreviations and acronyms the first time they are used in the text, even after they have been defined in the abstract. Abbreviations such as IEEE, SI, MKS, CGS, sc, dc, and rms do not have to be defined. Do not use abbreviations in the title or heads unless they are unavoidable.

Si units are recommended for use in formulas, drawings and tables., for example the SI unit for magnetic field strength H is A/m. Apply the center dot to separate compound units.

Do not mix complete spellings and abbreviations of units: "Wb/m2" or "webers per square meter," not "webers/m2." Spell units when they appear in text: "...a few henries…", not "...a few H…".

Use a zero before decimal points: "0.25," not ".25." Use "cm3," not "cc."
