Abstract

The invention provides a stator core and a motor. The stator core comprises a first core part and a second core part, wherein the first core part is formed by overlying a plurality of first laminations along the axial direction of the stator core or by adopting a first magnetic conduction material to be processed; and the second core part is formed by overlying a plurality of second laminations along the direction vertical to the axial direction of the stator core or by adopting a second magnetic conduction material to be processed. Due to the fact that the first core part is formed by overlying a plurality of first laminations along the axial direction of the stator core or by adopting the first magnetic conduction material to be processed and the second core part is formed by overlying aplurality of second laminations along the direction vertical to the axial direction of the stator core or by adopting a second magnetic conduction material to be processed, the magnetic conduction rate of the stator core is effectively improved through the effects of the first laminations and the second laminations which are staggered and laminated.

Description

Technical field [0001] The present invention relates to the technical field of driving devices, in particular to a stator core and a motor. Background technique [0002] Traditional permanent magnet synchronous motor stator core 10’ such as figure 1 Shown. It is characterized in that the tooth yoke 11' and the pole shoe 12' have the same width in the axial direction. For adopting figure 1 In the conventional surface-mounted permanent magnet synchronous motor with the stator core 10' structure shown, the length of the magnet 20' in the axial direction is generally greater than the height of the stator core 10'. figure 2 Shown. [0003] Since the output of the permanent magnet synchronous motor depends on the combined effect of the stator and rotor magnetic fields, in the traditional surface-mount permanent magnet synchronous motor, the magnetic field of the "magnet higher than the core" on both sides of the magnet 20' needs to pass through the air gap and interlink with the stator...
