Abstract :
The high speed permanent magnet (PM) machine has been widely investigated since it has small size, high efficiency and power density. However, due to the high rotor speed and high frequency of the stator flux variation, the design of a high speed machine is quite different from designing a conventional machine. This paper will pay attention to the design of stator core and stator winding for a high speed PM machine. A comparative study on the influence of different stator structures on machine performance for a same PM rotor is carried out based on the magnetic field analysis
