“…As a typical topology of PM motors, the interior permanent magnet (IPM) motors with a V-shape provide a more superior performance of the flux-weakening capability and wider constant-power speed range [7][8][9][10], achieving considerable attention. Along with these excellent advantages, IPM motors offer a great alternative opportunity to contribute for a more rational use of energy, which makes EVs have the potential to provide a perfect solution to energy security and environmental impacts in the future [11,12].…”

Abstract:Interior permanent magnet (IPM) motors are widely used in electric vehicles (EVs), benefiting from the excellent advantages of a more rational use of energy. For further improvement of energy utilization, this paper presents an analytical method of d-and q-axis inductance calculation for IPM motors with V-shaped rotor in no-load condition. A lumped parameter magnetic circuit model (LPMCM) is adopted to investigate the saturation and nonlinearity of the bridge. Taking into account the influence of magnetic field distribution on inductance, the winding function theory (WFT) is employed to accurately calculate the armature reaction airgap magnetic field and d-and q-axis inductances. The validity of the analytical technique is verified by the finite element method (FEM).

Permanent magnet flux switching machines (FSPMs) have attracted considerable attention in recent years, due to their outstanding characteristics to operate as brushless AC drives. Since they are relatively new, there are particular challenges not only for their design procedure but also for their operating principle comprehension. This study highlights several issues on FSPMs from the basic operation description to their key design points. After a comprehensive description of FSPMs working principles, a detailed discussion is presented on their armature winding design. In addition, this study reviews various methods for their performance modification, including torque profile, electromotive force, and loss characteristics. This study also surveys field regulation technologies, modelling and design optimisation methods applied to FSPMs along with their fabrication and cost issues.

Compact stator structure of flux switching machines (FSMs) encompassing both permanent magnets (PMs) and armature winding slots (AWS) attract research interest whenever high power and density are the basic requirements. However, it also results in temperature rises owing to heat generation by electromagnetic power losses degrading the electromagnetic performance and affecting machine performance. In this study, a segmented permanent magnet (SPM) consequent pole FSM (SPM-CPFSM) is developed, which provides a stator cooling channel (duct) for improved heat dissipation to avoid demagnetization of PM as well as overheating. Furthermore, this study investigates detailed electromagnetic performance analysis and prediction of temperature variation in various machine parts owing to the heat generated by iron, copper, and magnet eddy current losses utilizing coupled electromagnetic-thermal analysis accounting for magnetic flux density variation. In comparison with the 2D analysis, the developed 3D coupled-field analysis more accurately predicts electromagnetic performance and temperature distribution. Analysis reveals that a cooling duct at the stator significantly assists in stator heat dissipation in the axial direction ensuring a safe operating condition of the PMs as well as machine parts to avoid overheating.
