1. A segmented core, wherein the segmented core comprises a laminated core and a soft magnetic composite (SMC) core wound around with a coil, the SMC core is coated on a periphery of the laminated core,
along a laminating direction of the laminated core, a length of the whole SMC core in the direction perpendicular to the laminating direction is gradually increased; and
the SMC core comprises a first SMC core and a second SMC core, the first SMC core comprises an SMC winding bar and an SMC embedded groove arranged on the SMC winding bar, wherein a periphery of the SMC winding bar is configured to set the coil, and the laminated core is installed in the SMC embedded groove, and wherein the SMC winding bar covers the laminated core in a circle,
wherein a first end of the SMC winding bar close to the SMC embedded groove is provided with a first positioning protrusion and/or a first positioning hole that is adapted to the second SMC core;
the first end of the SMC winding bar that is set with the SMC embedded groove is provided with a second positioning protrusion and/or a second positioning hole that is adapted to the second SMC core;
wherein in a case that the first positioning protrusion and the first positioning hole are both provided, the first positioning protrusion and the first positioning hole are arranged symmetrically, and a size of the first positioning protrusion is adapted to a size of the first positioning hole; and
in a case that the second positioning protrusion and the second positioning hole are both provided, the second positioning protrusion and the second positioning hole are arranged symmetrically, and a size of the second positioning protrusion is adapted to a size of the second positioning hole.
