High-temperature superconducting (HTS) materials, including bulks and tape stacks, have shown high current-carrying and field-trapping capacity in previous studies, which makes them employed in the synchronous motors (SMs) as a substitute of permanent magnets (PMs). When used as rotor magnets, hybrid magnets (HMs) made of HTS tape stacks and PMs show remarkable advantages compared with bulks...
Superconducting magnetic levitation (maglev) is developing rapidly in recent decades for its incomparable features like ultrahigh cruising speed. To develop the second generation high tempera-ture superconducting (2G HTS) maglev, a serious of work has been done by us including design of propulsive system, optimiza-tion of 2G HTS magnet system, energizing tests and over-current duration tests....
Linear oscillating machines (LOMs) can control linear reciprocating motions through stroke cycles at specific frequencies. A single-phase, short stroke LOM has been developed for use in refrigeration compressors and other similar devices, because of their high transmission efficiency and simple structure. Generally, conventional LOMs are designed as cylindrical structures. However, such...
Permanent magnet synchronous machines (PMSM) are becoming an essential technology for applications such as home appliances, industrial tools, and electrical vehicles. Todays, consumer demands for noise and vibration of products are increasing, and studies on the noise and vibration characteristics of motors that generate power are actively being conducted. One of the factors contributing to...
In recent years, flux-modulated principle is investigated extensively in diverse permanent magnet (PM) motors due to the prominent advantages of low-speed and large torque capability. And then, a new electrical machine family, nominated as flux-modulated PM (FMPM) motor, is formed gradually. Interestingly, the FMPM motors break through the traditional motor design rule that the pole-pairs of...
This paper presents the research work for a novel dual-stator composite-rotor synchronous machine (DSCRSM). Ferrite permanent magnets (PMs) are used for the composite rotor with flux barriers, while the axis of each PM pole is located as 45 degree (electrical) with respect of the axis of the corresponding flux barrier. Compared with the conventional permanent magnet-assisted synchronous...
Recently, permanent magnet synchronous motors (PMSMs) have been widely used in the industry owing to their various advantages, such as high-speed operation, high efficiency, and compact design. However, PMSMs have the drawback of noise and vibration, which is caused by local force generated by the interaction between the stator and rotor magnets having high magnetic energy, significantly...
Dual mechanical port flux-switching permanent magnet (DMP-FSPM) machine with high power density, high torque density, and wide operation range has potential application prospect in electric vehicles (EVs). The DMP-FSPM machine is consist of inner rotor, outer rotor and middle stator which can be regarded as the combination of two conventional flux-switching permanent magnet (FSPM) machines....
Tubular flux-switching permanent magnet motor (TFSPMM) is a special kind of permanent magnet machine with the permanent magnet (PM) installed on the stator side and there is no winding or PMs on the mover side. Among various kind of linear machines, TFSPMM draws a great interest from researchers for its robust structure, high drive force density and low material cost required. Compared with...
Compared with Linear Induction Motor (LIM) which is widely applied in urban railway transit system, Linear Flux-Switching Motor (LFSM) has the merits of high power density, high efficiency, while the secondary of LFSM is robust and simple. Hence, LFSM is claimed to be promising for urban railway transit system.
Generally, LFSPM can be classified as Linear Wound Field Flux-Switching (LWFFS)...
This paper describes a study on the shape design of Magnetic-geared synchronous Motor for improvement of performance and securing rigidity. The Magnetic-Geared synchronous Motor(MGM) is an all-in-one structure of a magnetic gear and a permanent magnet synchronous motor, and is an electric machinery capable of operating both functions. In this study, the existing surface-mounted type is set as...
