Analytical Prediction of Magnetic Field in Parallel Double Excitation and Spoke-Type Permanent-Magnet Machines Accounting for Tooth-Tips and Shape of Polar Pieces

“…3, the ith slot subdomain (region III) where i vary from 1 to Q s (Q s is the number of stator slots) is associated with boundary conditions at the bottom and at each sides of the slot as The boundary condition (9), leads to the eigenvalues and eigenfunctions of the partial differential equation (8) as shown in details in [26]. The eigenfunctions are called spatial frequencies of the considered region [23].…”

“…In reference [5], exact analytical calculation of magnetic field distribution is developed for a slotted stator series double excitation machine, where coils current excitation are situated in the slotted rotor with radial surface mounted permanent magnets. There are other structures of double excitation permanent magnet machines with complicated geometry [6]- [8], where the study is done by finite element method only.…”

Design Improvement of Three Phase 12Slot-14Pole Outer Rotor Field Excitation Flux Switching Motor

“…Generally, the flux switching motor (FSM) can be categorized into three groups that are permanent magnet flux switching motor (PMFSM), field excitation flux switching motor (FEFSM), and hybrid excitation flux switching motor (HEFSM). Figure 1 illustrates the classification of FSM [7]. Their rotors are salient and robust without windings or permanent magnet (PM)), and are matching to that of switched reluctance machines.…”

Electromagnetic flux analysis on a new outer-rotor hybrid excitation flux switching machine

“…Furthermore, all magnetic flux sources such as PM, DC field excitation coil (FEC) and armature coil are located on the stator body makes the temperature rise is easily managed. Hence, the proposed machine is expected can provide much higher torque and power density when compared with the IPMSM that conventionally employed in EV/HEV [7].…”
