Axial-flux motor core device with water cooling structure

Abstract

The invention discloses an axial-flux motor core device with a water cooling structure. The device comprises a stator core machined in a segmental manner, a core fixing block, an S-shaped spring, a cooling water pipe pressing plate, and a cooling water pipe. The front end of the core is provided with a groove, and the open side of the groove is clamped to the core fixing block. The cooling water pipe passes through the groove, and closely fits the other side of the groove. One side of the cooling water pipe pressing plate closely fits the outer wall of the cooling water pipe, and the other side is a plane and contacts the S-shaped spring. The S-shaped spring is fixed between the cooling water pipe pressing plate and the core fixing block, and is always in a compressed state. The spring presses the cooling water pipe pressing plate. According to the invention, the problems in the existing axial-flux motor stator core such as high cooling difficulty, complex structure, high processing difficulty and high cost are solved, and the structure has very good installation extension performance and can satisfy the requirements of high-power axial-flux motor installing and cooling.

Description

technical field [0001] The invention belongs to the field of axial flux motors, and more specifically relates to an axial flux motor iron core device with a water cooling structure. Background technique [0002] The existing axial flux motor iron core is processed by "punching" and "rolling" methods, using servo equipment to control the groove pitch, punching grooves on silicon steel sheets, and then rolling them into a disc structure. For example, the patent document whose patent application number is CN200810041184.0 discloses a manufacturing method for the stator core of a disc motor. On the tape release reel, the tape reel will send the electrical steel coil to the feeding table at regular intervals, and the electrical steel coil will be sent into the stamping die by the feeding table to punch out the groove shape, and the electrical steel coil tape after the groove shape is rewound The coil is wound into an iron core disc. The above processing method is to punch a sing...

Problems solved by technology

However, the punching and rolling equipment involved in the above has a complex structure, slow processing speed, and when the diameter of the axial magnetic flux core increases, different winding tooling needs to be processed. If the diameter is more than 2 meters, the feeding mechanism and The precision of the winding mechanism is difficult to control, and the smoothness of the processing plane is poor, which is not conducive to the integration of cooling pipes, thus hindering the promotion of axial flux motors
