“…As a consequence of the relative complexity of the stator geometry, the field distribution is highly three-dimensional (3-D), and although 3-D finite element analysis has been employed for such a machine topology [8], this is inappropriate during the initial stages of design. However, the geometry of the stator is too complex to enable a full analytical field model to be derived.…”

Abstract-The paper describes a methodology for optimizing the design and performance of a miniature permanent-magnet generator and its associated energy storage system. It combines an analytical field model, a lumped reluctance equivalent magnetic circuit, and an equivalent electrical circuit. Its utility is demonstrated by means of a case study on a 15-mW, 6000-r/min generator, and the analysis techniques are validated by measurements on a prototype system. Index Terms-Design optimization, energy storage system, miniature permanent-magnet generator.

“…Compared with the EECA, the maximum value is increased by 24.4%. (3) When the excitation current in the range from 0 to 10A, the excitation current of the HEBCA is less than the EECA's. So, the HEBCA has the less excitation loss.…”

Abstract. In consideration of low power density of electric excitation claw-pole synchronous alternator (EECA) and some difficulties in magnetic field regulation of permanent magnet claw-pole synchronous alternator (PMCA), a novel hybrid excitation brushless claw-pole alternator (HEBCA) is proposed in this paper. Its structure and field control principle are described. Three dimensional finite element analysis is used to obtain the no-load magnetic field distributions and field control capability under different field currents. The result shows that the flux of the prototype machine can be adjusted over a wide range with a relatively low field current.

-This paper proposes a method to calculate magnetostrictive forces, displacement, and vibration modes of a large-scale Brushless DC(BLDC) motor by using a magneto-mechanically strong coupling formulation. The force is calculated using the energy method with magnetostrictive stress tensor. The mechanical vibration modes are also analyzed by using the principle of Hamilton and the calculated magneto-elastic forces acting on the surfaces of the stator. To verify the algorithm, 3 MW BLDC motor is simulated, and the forces, displacements, and vibration modes are calculated. The result shows that the mechanically stressed core has more deformation or displacements than those of the normal condition.
