Surface mounted permanent magnet synchronous machines are nowadays used in a wide range of applications and power ratings, thanks to their high efficiency and ease of control. However, when used in high-speed applications, the need of some feature retaining the magnets increases the effective magnetic air gap, thus lowering the performance of the motor. This paper proposes a rather unconventional rotor structure based on the consequent pole arrangement. Different rotor topologies are discussed and compared.

Abstract
Surface mounted permanent magnet synchronous machines are nowadays used in a wide range of applications and power ratings, thanks to their high efficiency and ease of control. However, when used in high-speed applications, the need of some feature retaining the magnets increases the effective magnetic air gap, thus lowering the performance of the motor. This paper proposes a rather unconventional rotor structure based on the consequent pole arrangement. Different rotor topologies are discussed and compared.File in questo prodotto:
