“…Because of its excellent performance and simple process, it has been the focus of research and development of material science since the 1980s. Different from the traditional silicon steel sheet [25,26], the physical characteristics of amorphous alloy material are thin, brittle, and hard, leading to stamping process difficult and die wear fast, increasing process cost, so its production cost is relatively high. Therefore, amorphous alloy often exists in the form of winding process in practice.…”

A bearingless induction motor (BL-IM) is a new type of motor integrating suspension and rotation functions. Higher requirements are put forward for its suspension performance. Due to the material advantages of a new type of amorphous alloy with high magnetic conductivity, low loss, and low coercivity, it is considered to be used in the BL-IM rotor to reduce iron loss and improve the electromagnetic performance of the BL-IM. Finite element analysis software is used to analyze the performance of two different kinds of motors with the rotors made of conventional silicon steel and amorphous alloy, respectively. The magnetic field density distribution, torque, speed, and radial force are compared between the two motors. The results show that the speed of amorphous alloy motor increases faster, and the rotor has better suspension characteristics. Moreover, the amorphous alloy material has a smaller density; the material properties can effectively reduce the weight of the motor; it is beneficial to the operation of the BL-IM in special environments.

“…In addition, the hysteresis loss is also small because it has no crystal structure [6]. So far, there are many researches to apply the amorphous alloy into the core of classic motors such as a permanent magnetic synchronous motor (PMSM) [7][8][9][10][11], an induction motor (IM) [12], and a switched reluctance motor (SRM) [13][14][15]. In particular, Ref.…”

This study reveals the characteristics of switched reluctance motors (SRMs) made by blanking (a) 20HX1300 of high grade lowiron-loss silicon steel (0.20mm thickness) and (b) 2605SA1 of amorphous alloy (0.025mm thickness). The blanking of the amorphous alloy is an innovative technology for the mass production of the high efficiency amorphous-alloy-motor. The impact of the processing methods on the magnetic properties are evaluated using the ring cores processed by the following methods: the wire cutting and the blanking. On the other hand, the experiment with the SRMs processed by the blanking evaluates the characteristics depending on the material. As first prototype, 70W-SRM (40mm thickness) is manufactured by blanking 1600 sheets of the amorphous alloy and adhesively laminating them. In the experiment, the motor efficiency of the amorphous-alloy-SRM is improved by 6.9 p.t. compared with that of silicon-steel-SRM. In addition, the iron loss of amorphous-alloy-SRM is reduced by 78.7% compared with that of silicon-steel-SRM.

“…Four models are used to investigate the lightweight structure applied in stators [13], and the adoption of a high-performance soft magnetic alloy core can improve the power density of a PMSM. In [14], the iron loss of amorphous alloy and silicon steel sheets was compared by the finite element method. Through experimental verification, it was found that although the loss of amorphous alloy increased after manufacturing, it was still lower than that of silicon steel sheets.…”

Accurate prediction of core losses plays an important role in the design and analysis of flux-switching permanent magnet (FSPM) machines, especially during high-speed and high-frequency operation. Firstly, based on the numerical method, a high-frequency core loss prediction method considering a DC-bias magnetization component and local hysteresis loops as well as the harmonic effect is proposed. Secondly, the magnetizing characteristics of the silicon steel sheet and, consequently, the core loss of the electrical steel used as the core lamination are measured. Then, the loss coefficient of each core loss component is obtained by the data fitting tool. Based on the proposed method, the stator and rotor core losses of a three-phase, 12-stator-slot, and 10-rotor-pole (12/10) FSPM machine with different soft iron materials and driving modes are calculated. Finally, the results of the numerical method are verified by conventional finite element analysis.
