Experimental evaluation of current carrying capacity of printed circuit stator coils

Design aspects, winding arrangements and applications of printed circuit board motors: a comprehensive review

“…Consequently, the usual temperature rising in round‐wire AFPM motor under the air‐cooling condition is 70–80°C [70–72]. However, as stated in [18], PCB windings have the capability to be driven with very high current density 5 to 10 times higher than conventional round‐wires, while keeping the temperature rise within the allowable ranges. Thus, the stable rise of temperature in the PCB winding is 30°C under the same condition while the current density of the PCB winding is 6 A/mm 2 .…”

“…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].…”

“…Furthermore, it has been demonstrated that this technology is an attractive applicable option to be used in rotating machines construction, which allows the machine structure and the necessary conductors for power conversion to be manufactured simultaneously [8]. PCB motors are relatively small sort of motors that have some unique advantages such as compact size [6, 9–12], high efficiency [9, 10, 13, 14], high power density [14, 15], reduced acoustic noise [6, 16], superior achievable current density [17, 18], and low‐cost [1, 10, 11, 19]. They allow design flexibility [11, 20], have simple construction and maintenance [21], and minimise the harmonic component in the back electro‐motive force (EMF) of the motor [5, 13, 22].…”
