“…The approximation of the synchronization region by a trigonometrical function that strictly depend on δ s is often used in literature [11][12][13][14][15]. Although this approximation can simplify the synchronization calculation, it also compromises the accuracy of the synchronization model.…”

“…As an alternative, the use of an analytical synchronization model has been proposed by researchers such as Honsinger [10], Miller [11], Rahman et al [12][13][14], and Soulard and Nee [15]. These analytical models are very efficient and can be readily implemented into a design optimization routine to minimize the use of costly transient time-step FE simulations [16,17].…”

Abstract-A main challenge in designing line-start permanent magnet synchronous motors is synchronization analysis and determination. The transient time-step finite element simulations are often required in the design process, which is computationally expensive. An attractive alternative is to use an analytical synchronization model, which is time efficient and thus viable to be included in an optimization procedure. In this paper, two variants of the energy-based analytical synchronization model are proposed. Their viability and performance are compared with those of the existing analytical method and validated by transient finite element simulations. It is shown that the proposed methods have a better resolution and accuracy in determining the synchronization status of line-start permanent magnet motors.

Abstract-This paper presents two design-and-analysis cases of a linestart axial-flux permanent-magnet motor: with solid rotor and with composite rotor. For a novel structure of the motor, two concentric unilevel spaced raised rings are added to the inner and outer radii of its rotors to enable auto-start capability. The composite rotor was coated by a thin (0.05 mm) layer of copper. The basic equations for the solid rotor ring were extracted. The motor's lack of symmetry necessitated 3D time-stepping finite element analysis, conducted via Vector Field Opera 14.0, which evaluated the design parameters and predicted the motor's transient performance. Results of the FEA show the composite rotor significantly improving both starting torque and synchronization capability over solid rotor.
