This paper investigates the profile of the copper losses in a 5.0-MW high-speed permanent-
magnet machine with form-wound winding. The machine was tested, and the test data were …

New types of heavy litz wires with noninsulated or insulated strands are offered for high-
power low-voltage electrical machines, where skin and proximity effects can cause serious …

The growing trend of high speed, high power density machines for applications such as EVs,
aerospace and machine tools demand these machines to work at higher electrical …

Electrical machines with stranded random windings often suffer from considerable
circulating current losses. These losses have been poorly studied because of the difficulty …

Analytical calculation of circulating and eddy currents in windings has been under research
for almost a century, yet the calculation accuracy has improved slowly. However, over the …

This paper deals with the optimization for performance and cost of the low-power permanent
magnet synchronous machines used in automotive applications with focus on particularities …

AC copper loss from stator winding is one of the main losses of the high-speed permanent
magnet machines (HSPMMs) and directly affects the performance of the machines. AC …

Electrical machines often utilize stranded parallel conductors to reduce the skin-effect
losses. This practice can lead to uneven total current distribution among the strands …

Finite-element (FE) analysis of winding losses in electrical machines can be computationally
uneconomical. Computationally lighter methods often place restrictions on the winding …

In high performance electric machines, the increase of fundamental frequency leads to
additional losses in the winding due to parasitic effects such as the associated skin and …
