Abstract: A segment core and an axial flux motor. The segment core is formed by covering an SMC core (100, 100?) over an outer peripheral surface of a laminated core (200, 200?). An outer surface of the segment core, which can not be processed easily, is shaped by processing the easily shapeable SMC core (100, 100?). The entire structure of the laminated core (200, 200?) is relatively simple, and thus a mold for processing the laminated core (200, 200?) requires simpler specifications. Moreover, the mold can be used to perform processing easily, to reduce difficulties of processing the segment core. The segment core has better electromagnetic performance than a segment core solely using an SMC material, and has a higher core utilization rate than a segment core solely using a laminated core (200, 200?).

Abstract: A winding die is disclosed, including: a gear baffle, where a middle portion of the gear baffle is provided with a first opening for placing an iron core post, and the gear baffle is provided with a first surface; and a cylinder, where the cylinder is arranged on the first surface of the gear baffle and connected with the gear baffle. The middle portion of the gear baffle is provided with the first opening for placing the iron core post, the gear baffle is fixedly connected with the cylinder, an external device is connected with a gear, and the cylinder on the gear baffle is driven to rotate around the iron core post by pulling the gear, so that a foil or an insulating material on the cylinder can be wound on the iron core post, finally realizing a foil winding.

Abstract: A winding cylinder of a stereoscopic wound iron core transformer is disclosed, including an outer cylinder, an inner cylinder and a tension assembly. The outer cylinder is movably connected with the inner cylinder through a bearing assembly, and the outer cylinder rotatable around an axis of the inner cylinder. The tension assembly includes a screw, a spring and a connecting assembly. The connecting assembly includes a fixing portion, a friction portion and a transmission portion, the friction portion and the transmission portion are both arranged around the inner cylinder, and the transmission portion is fixedly connected with the outer cylinder. A side face of the inner cylinder is provided with a through hole, and the fixing portion penetrates through the through hole and is fixedly connected with the friction portion.

Abstract: A cooling structure for a disk electric motor, and a disk electric motor are provided. The cooling structure includes: a stator core, a stator housing, multiple first baffles and multiple second baffles. Multiple coils are arranged on the stator core, and there is a gap between adjacent ones of the coils; a stator housing enclosing two end faces of the stator core, where a first cavity is defined by the stator housing and an outer side of the stator core, a second cavity is defined by the stator housing and an inner side of the stator core, where the first cavity and the second cavity are in communication with each other through the gap, and a liquid inlet and a liquid outlet which are in communication with the first cavity are arranged on the stator housing.

Abstract: A cooling structure for a disc electric motor is provided, including a stator core, a stator housing, a first baffle, a second baffle, a first coil, a second coil, and a partitioner. The first coil and the second coil are arranged on each of stator units. First coils on adjacent stator units are in a close fit with each other, and second coils on the adjacent stator units are in a close fit with each other. The partition plate is interposed between the first coil and the second coil. A third cooling channel, through which a first cavity and a second cavity are communicated, is formed between the adjacent stator units.
