Electromagnetic Design and Modeling of a Two-Phase Axial-Flux Printed Circuit Board Motor

WAVED: A Coreless Axial Flux PM Motor for Drive Systems with Constant Power Operation

“…Each of the two stators has a two-phase winding. and reduction in dimensions and mass can be achieved by employing printed circuit board stator structure as shown for example in [11], [12].…”

“…The rated torque is selected based on acceleration requirements. The wave winding can also be implemented using printed circuit board technology [12].…”

Multiphysics analysis of printed circuit board winding for high‐speed axial flux permanent magnet motor

“…A coreless stator has been used to eliminate cogging torque, reduce axial magnetic force, eliminate stator core losses, and to make the assembly simple. A printed circuit board (PCB) winding can provide compact and reliable stator winding [5][6][7][8]. By eliminating the use of an iron core and copper wires for stator windings, the motor with high power density can be achieved [9,10].…”

Comparative analysis of wave winding topologies and performance characteristics in ultra‐thin printed circuit board axial‐flux permanent magnet machine

“…The selection of coreless structures is attractive because it not only reduces the overall weight of the whole system but also eliminates unwanted characteristics such as the cogging torque and the losses. Among different coreless topologies, an attractive candidate is the AF-PMSMs with printed circuit board (PCB) windings [14][15][16][17][18][19][20][21][22][23][24][25][26]. The narrow and the planer structure of the PCB winding AF-PMSMs make them an appropriate candidate for applications which require thinner designs such as home appliances with planer geometries, spindle motors for hard disk drive and digital video disks [18][19][20][21].…”
