IEEE Transactions on Magnetics, 2021
The axial-flux permanent magnet vernier machine (PMVM) is a competitive machine applied in the field of direct-drive which features on low speed and high torque. The rotor of axial-flux PMVM has a tendency to deflect to stator under the effect of the large and unbalanced axial electromagnetic force, which probably results in the collision between rotor

Behaviors of Axial and Radial Electromagnetic Force for Cryogenic Disk Motor
IEEE Transactions on Energy Conversion, 2021There are axial and radial electromagnetic forces between the stator and rotor of axial flux disk motor besides the useful torque. The electromagnetic forces act on the rotor and are crucial to the stable operation in magnetic levitation applications driven by disk motor. This article concerns the behaviors of axial and radial electromagnetic forces of

Reducing Acoustic Noise of Axial‐Gap SRMs by Decreasing Axial Electromagnetic Force Ripple
Electrical Engineering in Japan, 2016SUMMARYSwitched reluctance (SR) motors are motors that utilize the reluctance torque originating in the magnetic saliency between the stator and the rotor, which are made up of an electromagnetic steel sheet and windings without a permanent magnet. Because of their robustness and simple structure, SR motors are suited for use as the in‐wheel motor for ...

Dynamic Response and Critical Velocity of Rails in Electromagnetic Rail Launcher Due to Axial Force
IEEE Transactions on Plasma Science, 2020The dynamic response and the critical velocity of the rails in electromagnetic rail launcher (EMRL) have a direct influence on launch accuracy and contact between the armature and the rail. In order to analyze the influence of the axial force on the dynamic response of the rails in EMRL during the launching process, the vibration control equation of ...

In this paper, a novel electromagnetic negative-stiffness spring (ENSS) is constructed by coaxial permanent annular magnets and coils with rectangular cross section. The stiffness of the ENSS is negative when the coils carry exciting current. In the stiffness characterization study, the analytical model of the ENSS based on filament method is ...
