For a new type of toroidal permanent magnet linear motor(TPMLSM), this paper analyzes the thrust fluctuation in constant acceleration operation motor from Angle cogging force motor. whose structure has been determined and processed, structural parameters cannot be changed, its performance improved perspective body. Therefore, tries to consider influence on normal control. In paper, starting bod...

Aiming at the optimization of cogging torque 12 pole 36 slot embedded permanent magnet motor, analyzing generation principle torque, putting forward design auxiliary based on Taguchi method, using Maxwell finite element simulation tool, and selecting optimized data, through orthogonal experiment data processing, finding final scheme slot. The results show that, method can effectively suppress u...

Permanent magnet (PM) machines with tooth coil windings are designed and analyzed. We study how the slot wedge material affects the behavior of PM losses when using tooth coil windings, which generate a significant air gap flux density harmonic content. The losses and cogging torques of a surface permanent magnet rotor and an interior permanent magnet rotor are compared in no-load and load situ...

To develop a fault tolerant machine with the least redundant phases, the inductance model and a nonlinear radial air gap flux density model of a new four-phase doubly salient electromagnetic generator (DSEG) is presented and verified by the finite element analysis (FEA) and experiments result in this paper. With the proposed formulas, a new four-phase 24-slot 18-pole DSEG without cogging torque...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

This paper presents a novel topology of dual airgap radial flux permanent magnet vernier machine (PMVM) in order to obtain higher torque per volume and similar average compared conventional PMVM machine. The proposed contains two stators sandwiched yokeless rotor. rotor helps reduce the by providing an effective linkage stator windings. improved competitiveness was validated using 2D finite ele...
