Permanent magnet synchronous machines (PMSMs) are particularly energy efficient solutions in the modern chemical, mining and automobile industries. The properties of speed-controlled electrical drive systems enable PMSMs to save maximum energy. If electric machines are operated in an explosive atmosphere, it must be ensured that the maximum surface temperature remains below the ignition temperature...
The permanent magnet synchronous machine with an external rotor is the most important device for high performance electrical drive systems in particular for hybrid electric vehicles. The paper presents finite element analyses of a such a machine in terms of a comparison of both Y- and Δ-connected stator windings. The influence on the most important design parameters such as electromagnetic torque...
