Multi-domain analytical rotor model with buried permanent magnets in V-arrangement for high-speed applications

“…Therefore, only the V-, T-and Δ-arrangement are analyzed further. These topologies are compared based on state-of-the-art machine designs published in [2] and [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], which are either used in series production or have been studied in a research context on test benches (Fig. 2).…”

“…2. Influence of permanent magnet arrangement on high-speed capability based on machine designs found in [2] and [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Only rectangular shaped permanent magnets are used for the compared V-and Δ-arrangements. The T-arrangement is distinguished between permanent magnets with a rectangular and a concentric shape.…”

“…The technically usable circumferential velocity 𝑣 p,max is the minimum of the bridge related terms, Eq. (10).…”
