Fully superconducting synchronous motors have great potential to achieve a high-power density (kW/kg), which is very attractive technology for future electric propulsion systems for aircraft applications. This system is expected to be operated with low voltage (several kV) and large current (several hundred A or more). Hence, the armature coil is required to have a large current capacity. In...
High-temperature superconducting (HTS) synchronous condensers have demonstrated exceptional potential in enhancing grid stability and providing rotational inertia, particularly in power systems with a high proportion of renewable energy. By incorporating HTS magnets into rotor systems, these devices improve dynamic support performance, reactive power regulation, and grid inertia, addressing...
The regular partitioned stator flux-switching permanent magnet (PS-FSPM) machine integrates both permanent magnets (PMs) and armature windings within a single stator, providing significant space utilization for both the inner and outer stators. However, the PMs on the inner stator limits torque enhancement to adjustments in the pole arc coefficient. To overcome this limitation, a PS-FSPM...
Permanent magnet motors use rare earth permanent magnets that are sintered light rare earth elements (Nd, etc.), heavy rare earth elements (Dy, Tb, etc.), and iron. Currently, since heavy rare earth element imports depend entirely on specific countries, high-performance permanent magnets that exclude heavy rare earth elements have been developed in order to stabilize the domestic supply chain....
The motor with magnetic bearings has a structure in which the shaft is magnetically levitated outside the rotor, which can reduce friction loss, but increases the size of the motor system. Since the size of the motor system increases, it is not appropriate because it goes against the industrial demand for weight reduction and miniaturization. In order to reduce the overall size of the motor...
In this paper, methods to reduce iron loss through same direction skew and halbach array by utilizing the shape freedom of 3D printing are proposed. Axial flux motors have a higher power density than radial flux motors and are advantageous in a multi-pole structure. However, in the case of an axial flux motor, it is difficult to manufacture through electrical steel sheet lamination for iron...
Magnetic gears have the advantages of overload protection, no lubrication, fixed transmission ratio, and have broad application prospects in the field of low-speed and high-torque transmission. They can be used for motors, hydro-wind power generation, space gravity-free transmission, etc. Magnetic gears not only have research value for electrical disciplines, but also open up new ideas in...
The rotors of conventional rotor flux switching permanent magnet (R-FSPM) motor are all fractured and require non-magnetic materials for support to avoid the permanent magnetic field being closed in the rotor, which will reduce the mechanical robustness of the rotor. In order to overcome the above limitations, a V-shaped combination of magnetic poles rotor permanent magnet flux-switching...
