This paper presents a flux-switching permanent magnet machine for application of automotive integrated-startergenerator (ISG). Firstly, a typical three-phase flux-switching permanent magnet machine topology and its advantages are introduced. Secondly, optimal design of the machine to maximise torque capability is studied and final design data is given as the global optimisation for the target I...

In this paper, a dual-rotor slotless axial-flux permanent magnet (AFPM) motor with equidirectional toroidal winding (ED-TW) is proposed and compared the AFPM traditional (T-TW) same dimensions, number of coils poles. Different from T-TW, only positive sides ED-TW are left on one side stator core, return all removed to other core. Firstly, structure operation principle two motors introduced anal...

This paper suggests a method to improve the performances of Dual Stator Axial Flux Spoke-type Permanent Magnet (DSAFSPM) machines with phase group concentrated coil (PGCC) windings, by incorporating continuous and discrete step-skewing along special winding connection. The purpose study is mitigate cogging torque ripples while increasing output so it ameliorates machine performance at minimum c...

For aerospace applications, power density is a major driving force in the design of electrified powertrains. At forefront challenging electric motors with high efficiencies, torque, and capabilities. Due to its performance, Axial Flux Permanent Magnet (AFPM) Motor expected be one leading technologies meet demands these industries. Finding balance between cooling system’s effectiveness subsequen...

This paper presented an improved analytical method for calculating the open-circuit magnetic field in the surface-mounted permanent magnet machines accounting for slots and eccentric magnet pole. Magnetic field produced by radial and parallel permanent magnet is equivalent to that produced by surface current according to equivalent surface-current method of permanent magnet. The model is divide...

Recently the new topologies of permanent magnet (PM) motor attract a lot attention. These newly introduced PM motors are not mature in design aspects and suffer from different perspectives. Therefore, it is necessary to develop common procedure overcome these drawbacks. One problems with phenomenon irreversible demagnetisation (ID) at high temperatures. So, solution this problem will be present...

Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...
