Modification of the synchronous motor model for topological optimization

Abstract

<jats:p>Synchronous motors are increasingly used in industry, and they need to be made more energy efficient. To do this, it is possible to optimize the rotor of the synchronous motor by changing the design, obtaining the best option due to topological optimization. But the standard design of a synchronous motor is quite complicated for calculations by the finite element method, so it is necessary to simplify it as much as possible. To make all elements the simplest from the geometric point of view (rectangles, straight lines as much as possible, etc.), and to make for calculation not the complete model, but the smallest sector for which topological optimization can be adequately calculated. To do this, it is necessary to calculate the magnetic moment for a standard design, for each step of structural change, and compare these values. If there is a slight discrepancy in the data, it will be necessary to choose the sector correctly and confirm the adequacy of the model by comparison. All these calculations should be performed for the predicted model, which should be obtained after topological optimization.</jats:p>

The 5G revolution transforming connectivity and powering innovations

“…Moreover, 5G's use of Massive MIMO and sophisticated antenna technologies enhances signal strength and coverage, while also reducing interference [31,32]. This results in more reliable connections, higher throughput, and a more consistent user experience, even in densely populated areas or during peak usage times.…”

Topological optimization of the design of a permanent magnet synchronous motor using a genetic algorithm

“…This idea is not new, and it has been used in construction and strength calculations for a long time, and effectively. But for optimization of electric machine design, topology change is a relatively fresh area of research, and only in the last 5-10 years it has been actively developed [1][2][3][4].…”

Modeling of the thermal regime of a mobile electric vehicle charge unit

“…While the adoption of electric vehicles is accelerating at an unprecedented rate, the lack of charging infrastructure hampers the development of this market. To compensate for these shortcomings, mobile charging stations capable of providing charging services without restrictions on the location and timing of the charging process could play a prominent role in accelerating the penetration of electric vehicles [1,2].…”
