“…The electromagnetic modeling of AFPM motors is the next step of motor analysis after the sizing equation is determined, and the electromagnetic modeling is the basis of AFPM motor optimization design and performance evaluation. The electromagnetic model establishment and electromagnetic performance analysis methods of AFPM motors mainly include two mainstream methods: finite element analysis (FEA) [61] and magnetic equivalent circuit (MEC) [62]. Due to the inherent three-dimensional (3-D) structure and magnetic flux path, the magnetic flux density distributions along the radial and axial directions of AFPM motors show curvature effects and edge effects independently [63].…”

Axial-flux permanent-magnet (AFPM) motors are a kind of important motor with compact structure, high power density and high torque density. In this review, the progress of AFPM motors and their key technologies are analyzed and described, with emphasis on the topological structures, design and optimization methods and control techniques. Based on these analyses, the main findings of the review are the following: (1) the yokeless and segment armature (YASA)-type motors have great potential for development; (2) the multi-objective optimization design theories can be integrated and applied to optimize the design of AFPM motors; and (3) optimal control and sensorless control have important value in improving system reliability and reducing cost. Finally, highlights and prospects are provided for further advancing AFPM motors.

“…The operating principle of basic model linear motion [16] is the same as that in a conventional voice coil motor [24][25][26][27][28][29][30][31], as represented in 2D in Figure 9. Based on Figure 9, an MEC is presented in Figure 10(a), where Λσ is the permeance of the leakage flux, Λ0 is the permeance of the PM, ΛL1 and ΛL2 are the left parts of the stator and rotor axial steel sheet permeance values, respectively, ΛR1 and ΛR2 are the right parts of the stator and rotor axial steel sheet permeance values, respectively, and Λδ1 and Λδ2 are the permeance values of the linear air gaps.…”

This paper proposes a rotary-linear surface-mounted permanent magnet (PM) voice coil motor (RL-SVCM) with PM flux bridges in place of the iron flux bridges in a traditional RL-SVCM for enhancing average torque and force ripple but slight damage of torque ripple and average linear force. The iron flux bridges in a basic RL-SVCM cannot participate in the generation of rotary torque. In contrast, the PM flux bridges in the proposed RL-SVCM can participate in the generation of rotary torque. The magnetic equivalent circuit (MEC) is used to analyze the magnetic circuits of the basic and proposed models. The results explain the reasons for the performance improvements achieved by the proposed motor. The finite element method (FEM) is used to derive the precise output performance of the basic and proposed motors. Additionally, a prototype of the proposed RL-SVCM with PM flux bridges was manufactured for experimental verification. Close agreement between the experimental results and FEM results validates the feasibility of the proposed RL-SVCM.

“…The working principle of the rotary motion is mainly based on a traditional SPM motor, which has been analyzed in detail using MEC in numerous studies [20][21][22][23]. Differing from an RL-SVCM, there are two sets of flux bridges at the axial ends of the rotor, which is close to the PM and will generate a flux leakage, as compared with a traditional SPM motor.…”

In this paper, a rotary-linear motor that achieves rotary and linear motions with a simple oneair-gap structure, low rotary ripple, and smooth linear force is proposed. The proposed motor combines a five-phase unipolar surface-mounted permanent-magnet (USPM) and a voice coil structure to simplify the motor structure, which motor can be named as rotary-linear surface-mounted permanent-magnet voice coil motor (RL-SVCM). And because of the characteristics of the rotary five-phase armature circuit and linear voice coil circuit, the proposed motor can provide low rotary ripple and smooth linear force. For designing the motor, the magnetic equivalent circuit (MEC) method is used to study the relationship between the linear force performance and motor structure parameters, and the effect of the flux bridges on the linear force and rotary torque. Due to uncertain variables in MEC, the FEM method is used to analyze the precise output result of rotary torque and linear force, and non-interaction between rotary and linear motions.
