The integrated coil assembly comprises a first coil assembly, a second coil assembly, a third coil assembly and a fourth coil assembly; each coil assembly comprises a large-size coil loop, a medium-size coil loop and a small-size coil loop; the first coil assembly, the second coil assembly, the third coil assembly and the fourth coil assembly are mutually arranged in series; the large-size coil loop, the medium-size coil loop and the small-size coil loop of the first coil assembly are respectively and correspondingly connected to the small-size coil loop, the medium-size coil loop and the large-size coil loop of the second coil assembly; the small-size coil loop, the medium-size coil loop and the large-size coil loop of the second coil assembly are respectively and correspondingly connected to the large-size coil loop, the medium-size coil loop and the small-size coil loop of the third coil assembly; and the large-size coil loop, the medium-size coil loop and the small-size coil loop of the third coil assembly are respectively and correspondingly connected to the small-size coil loop, the medium-size coil loop and the large-size coil loop of the fourth coil assembly. By the integrated coil assembly, coils are compact at the two coil ends to save space, reduce the cost and the overall weight of the coil assembly and improve the motor efficiency. Moreover, the heat dispersion performance is improved to facilitate uniform distribution of heat.

Description

technical field [0001] The present invention relates to an improved integral coil used for example in a linear motor, in particular, the present invention relates to an integral coil assembly with multiple three-phase coils and a manufacturing method thereof. Background technique [0002] Current linear motors typically include coils that form a magnetic circuit to conduct current so that the motor generates a linear force. Generally speaking, the generation of linear force is directly proportional to the current passing through the electric coil winding and the magnetic induction intensity of the magnetic circuit. [0003] Due to the resistance of such coils, current passing through the coil windings generates heat. In some cases, overheating may result. This is due to the continuous high current output to obtain a sufficient force for moving heavy loads. So in this case, efficient cooling is necessary. [0004] Another problem associated with existing polyphase linear ...
