In order to solve the problems of complex structure and the difficulty of neutral adjustment of the existing 2D valve electro‐mechanical converter, a kind of claw pole magnetic levitation torque motor (CPMLTM) was proposed, which automatically suspended the rotor in an axially and circumferentially neutral position by using the cogging torque and axial recovery forces between the stator claw pole and the rotor permanent magnet (PM). Compared with the conventional moving iron torque motor, it has positive magnetic stiffness, 1.54 times higher PM utilisation and 33.6% lower mass. A qualitative mathematical model of output torque is derived based on equivalent magnetic circuit model. Then, the response surface method was used to build the second‐order response surface model, and NSGA‐2 was used to optimise the design of five key structural parameters, and the non‐inferior solution sets satisfying the maximisation of the cogging torque, output torque and axial recovery force were obtained. The experimental prototype was developed, and static experiments were carried out on the experimental rigs. The results show that the relationship between the input current and the output angular displacement of the CPMLTM is linearly proportional when the magnetomotive force generated by the coil winding is from −50 to 50 A.

“…In [6], Flux 3‐D software was used to investigate a magnetic field density map to validate the design of a claw pole permanent magnet synchronous machine. A three‐dimensional (3‐D) FEM model was developed in [7] to conduct power network analysis, in which the proximity and skin effects in the stator winding of a six‐phase claw pole alternator were considered. In [8], a 3‐D non‐linear time‐stepping FEM was used to calculate the magnetic field distribution.…”

High power-generation efficiency can be achieved by optimising the shape of the claw pole used as automobile generators. The working process of the stator and rotor in the claw pole generator was simulated using the finite-element method. First, one of the eight typical claw pole types commonly used in industry was selected. Then, orthogonal optimisation was performed based on the simulation results, yielding an optimal claw shape design. To examine the adaptability of the designed claw pole to shape change, the non-destructive test for evaluating the magnetic properties of claw pole (NDTEM) was employed. Finally, a claw pole with an optimal shape was forged, and its magnetic induction intensity was assessed using the NDTEM. The results indicated that compared with the unoptimised claw pole, the magnetic induction intensity of the optimised claw pole increased by a maximum of 8.11% and its weight reduced by 4.86%. This optimisation effectively improved the efficiency of power generation and achieved the lightweight of the claw pole.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.

“…In the literature, a large number of papers focus on the modelling of the claw pole machine, but often due to its complexity, assumptions are made. For example, eddy currents are frequently neglected [1], [2] or the electrical environment is replaced by simple electrical circuits [3]. Indeed, to ensure sufficient accuracy of the solution, the mesh needs to be sufficiently fine to preserve details of the rotor geometry and to take into account the eddy currents in the rotor.…”

3-D Numerical Modeling of Claw-Pole Alternators With its Electrical Environment

This paper describes a methodology for modelling a six-phase claw-pole alternator with its electrical environment. Magnetic nonlinearities, eddy currents and rectifiers are taken into account. To solve magnetodynamic problems, we use the modified magnetic vector potential formulation. The complex structure of the machine requires a 3D finite element analysis. To limit the mesh size, we introduced a refinement strategy based on the calculation of the time derivative of magnetic vector potential, solution of the magnetostatic case. In addition, we propose to reduce the transient state by improving the initial solution from the solution of a magnetostatic problem. These different numerical techniques reduce drastically the computational time and memory resources. To validate the proposed approach, some results are compared with experimental ones.
