In general, surface mounted PM synchronous motors (SPMSMs) are mainly adopted as a driving motor for high-speed applications, because they have high efficiency and high power density. However, the SPMSMs have some weak points such as the increase of magnetic reluctance and additional losses as a consequence of using a non-magnetic sleeve. Especially, the magneto-motive force (MMF) in the air-gap of the SPMSMs is weakened due to the magnetically increased resistance. For that reason, a large amount of PM is consumed to meet the required MMF. Nevertheless, it cannot help using the sleeve in order to maintain the mechanical integrity of a rotor assembly in high-speed rotation. Thus, in this paper, a multi-layer interior PM synchronous motor (IPMSM) not using the sleeve is presented and designed as an alternative of a SPMSM. Both motors are evaluated by test results based on a variety of characteristics required for an air blower system of a fuel cell electric vehicle.

“…This could improve the system efficiency, lower the noise, and reduce the volume of the entire system. The generator could also be used in mobile power stations and ensure the power supply in hospitals, commerce, and transportation as the emergency power [4]- [6]. Thus, the research on the SHSPMG is of significance.…”

In this paper, a superhigh-speed permanent-magnet generator (SHSPMG) which has an alloy sleeve on the rotor outer surface is investigated. The purpose of the sleeve is to fix the permanent magnets and protect them from being destroyed by the large centrifugal force. However, the sleeve material characteristics have much influence on the superhigh-speed machine, and therewith, most of rotor eddy-current losses are generated in the alloy rotor sleeve, which could increase the device temperature. Taking a 117-kW 60 000-r/min SHSPMG as an example, the influence of the sleeve on the generator output performance is analyzed when the generator sleeve is made of stainless steel, carbon fiber, copper-iron alloy, and copper. In addition, the eddycurrent loss distributions could be gotten, and therewith, the variations of the eddy-current losses in different kinds of sleeves are analyzed. Based on the 3-D coupling field between the fluid and temperature, the temperature distributions were obtained when the sleeve adopts different materials. Moreover, the temperature variations of the permanent magnets are further analyzed. The obtained conclusions may provide some references for the design and analyses of the SHSPMG.Index Terms-Eddy-current losses, electromagnetic field, rotor sleeve, superhigh-speed permanent-magnet generator (SHSPMG), temperature field.

Vibration signature has been proposed for fault diagnosis in electrical machines but its efficacy is hinged on proper determination of vibrating frequencies. Thus, this paper explores the applicability and performance of using vibration analysis on axial flux permanent magnet (AFPM) machine with asymmetric windings under static eccentricity (SE). The test rig developed to accurately replicate the faults is described and the vibration induced by electromagnetic forces associated with SE is investigated. The more dominant frequency component affected by the fault is the 2 nd harmonic of the magnetic force. The amplitude of the harmonic increased considerably with worsening SE. Along with other frequency components identified, it is proposed as an index for SE fault detection in AFPM machine.
