Problems solved by technology

[0004] The splicing between multiple iron core blocks and the installation of the iron core blocks on the casing will affect the stability of the formed stator core. The formed stator core has poor stability, which will not only deform due to vibration and other factors, but also affect the operating performance of the motor

Description

technical field [0001] The invention relates to the field of axial field motors, in particular to a stator core fixing structure of an axial field motor. Background technique [0002] Axial field motors have the advantages of small axial size, compact structure, high torque density and high efficiency. The axial field motor includes a stator, a rotor and a casing, the stator includes a stator core and coils arranged on the stator core, and the stator core is fixed on the casing by bolts. [0003] At present, the stator core structure mainly adopts SMC (Soft Magnetic Composite) iron core. The SMC iron core is made of high-purity iron powder as the main raw material. . The use of SMC iron core can reduce the size of the motor and reduce the loss. As the torque of the axial magnetic field motor increases, the volume of the iron core also needs to increase accordingly, but limited by the tonnage of the press, the iron core with too large volume cannot be pressed and manufactu...
