“…Parameters such as winding pattern, track thickness, number of turns etc. can be easily modified; however, certain constraints appear during the PCB manufacturing process [13, 22, 54]. (iv) Accuracy: since the software can do the work accurately, the required design specifications can be met easily [13, 22].…”

“…PCB motors have been used in a variety of industrial and domestic applications, where characteristics like compact size [6, 9–12], high efficiency [9, 10, 13, 14], high power density [14, 15], reduced acoustic noise [6, 16], high current density [17, 18], low‐cost [1, 10, 11, 19], dynamic stability and reliability [11, 22], design flexibility [11, 20], and easy integration with the power electronic circuit and control [21] for electrical motors are desired. Moreover, PCB winding minimises the harmonic component in the back EMF of the motor [5, 13, 22]. A comprehensive list of PCB motors from the literature is shown in Table 4, and the critical motor performance indices are thoroughly presented.…”

Printed circuit board (PCB) motors are witnessing increased interests and applications in the scientific communities and industry thanks to the advantages of compact size, high power density and efficiency, design flexibility, and low manufacturing cost. PCB has become a feasible and appropriate alternative to conventional round‐wire winding. It is applicable to any kind of electrical machines, such as axial‐flux machines and radial‐flux ones, in many applications. Moreover, it improves electromagnetic and thermal performances, which is affected by some design choices and winding arrangements. This study provides a comprehensive review of the PCB motors including the various aspects of initial electromagnetic design, performance analysis, winding arrangements, PCB coil design, and applications of PCB motors. Key references on the abovementioned aspects pertaining to the motor are discussed. Thus, offering researchers and engineers the most up‐to‐date information on the developments and progresses with the PCB motor design and technology.

“…In order to achieve concentrated fields in the air gap, the rotor magnets are arranged to form a Halbach ring [14]. The Halbach ring is buried inside the rotor core in order to protect the magnets from corrosion and to secure them against the centrifugal forces [13]. The winding is distributed uniformly around the stator disc, and hence, the flux enclosed by all the coils in a plane is the same.…”

Gearless and compact motors rotating at speeds above 10,000 rpm are finding many applications nowadays. This study presents the multiphysics modelling and analysis of a multilayer printed circuit board (PCB) stator for high-speed, lowpower axial flux permanent magnet motor. The possibility of circulating current in the multilayer PCB is studied. The two major effects of eddy currents at high frequencies: skin effect and proximity effect are investigated for the PCB winding. The losses in the PCB stator are estimated, and thermal analysis is performed to ensure reliable operation of the motor. MagNet 3-D and COMSOL Multiphysics are used, respectively for the finite element analysis and optimisation of the motor; and the simulation results are presented. A prototype of the motor is fabricated and tested to validate the simulation results.

“…However, axial flux structures have been discarded for several years because of high price of permanent magnet materials, difficulty of balancing, difficult axial lamination of slotted stator core, and assembly problems. With the development of permanent magnet materials and power electronic devices, the axial flux permanent magnet (AFPM) machine has attracted more attention due to its high torque density, high efficiency, high diameterto-length ratio (compactness), and low noise level [2][3][4][5][6][7][8]. The torque density of small size axial flux motors is twice as high as its radial flux counterpart [9].…”

Axial flux permanent magnet (AFPM) motors are usually controlled by drive; therefore, in the design of these machines the feeding voltage and frequency are completely independent parameters. Undoubtedly, the values of these parameters have significant effects on the performance characteristics of the machine. The main objective of this paper is to investigate the effects of these parameters on the efficiency of a double-sided TORUS-type nonslotted (TORUS NS) AFPM motor and propose a formula for selecting the optimal values of the feeding voltage and frequency at the beginning of the design process. To fulfill this goal, different machines with various speeds, powers, and feeding voltages are designed based on a proposed design algorithm. Then a formula for calculating machine efficiency is presented based on the frequency, number of pole pairs, output power, and feeding voltage of the machine. In order to confirm the validity of the proposed formula, several fabricated machines with different powers and speeds are selected as case studies. The efficiency of these machines is calculated using the proposed formula and is measured in the laboratory. Comparing the results confirms the excellent accuracy of the proposed formula.
