Disk-type iron core and disk-type motor

Abstract

The invention discloses a disk-type iron core and a disk-type motor. The disk-type iron core comprises an iron core pedestal which is in a disk-shaped structure, a plurality of first iron core tooth portions and a plurality of second iron core tooth portions, wherein the plurality of the first iron core tooth portions are arranged on an end surface of the iron core pedestal along a circumferentialdirection, and a first groove is arranged between the adjacent first iron core tooth portions; each second iron core tooth portion and the corresponding first iron core tooth portion are spliced together to form an iron core tooth for installing a coil, a second groove is arranged between the adjacent second iron core tooth portions, and each second groove and the corresponding first groove forma coil groove. By using the disk-type iron core, each second iron core tooth portion and the corresponding first iron core tooth portion are spliced together to form the iron core tooth for installingthe coil, and therefore, the coil can be embedded in a coil groove between the independent first iron core tooth portion and the independent second iron core tooth portion so that winding inserting is convenient, assembling difficulty of the coil is reduced, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of iron cores, and more specifically, to a disc-type iron core and a disc-type motor. Background technique [0002] Disc motors are also called axial field motors. The direction of the magnetic field inside the motor is along the axial direction, and axial field motors are generally flat. The iron core of the disc motor is divided into an integral iron core and a segmented iron core. The integral iron core is generally realized by winding silicon steel sheets. The stator core has a yoke. This iron core is generally wound by silicon steel sheets. To achieve better electromagnetic performance, it is generally designed as a semi-closed slot structure, which adds many difficulties to the coil off-line. [0003] Therefore, how to reduce the difficulty of assembling the coil and improve the assembling efficiency is an urgent problem to be solved by those skilled in the art.
