Totally 2 groups of the trimming structure, on the profile side opposite set on two, and every straight line of trimming structure is equal
It is connected with positioning arc.The vertical range that the trimming Yu the stator inner hole center of circle can effectively be reduced, reduces the usage amount of material.
The gradient of the bevel edge is 45 degree；Equal circular arc mistake is equipped between the bevel edge and straight line and profile side
Cross angle.45 degree of bevel edges and equal arc transition angle, convenient for carrying out the optimization arrangement of punching, technique arrangement effect by trimming structure
Fruit is more preferable, and stock utilization is higher.
The size range of the width d of the positioning arc is 0≤d≤20mm.Reasonable width dimensions can be effectively real
Now position.
A kind of stator core, including the stator punching that multiple axis directions along stator inner hole laminate, the stator punching
Piece is using stator punching described in any of the above item.Transport Safety is high, it is not easy to deformation of colliding with, stator core outer dimension
Appropriate to reduce, materials'use amount is small, improves the safety of bulk transport, and quality is more stable.
A kind of motor, including shell, rotor and stator core, the stator core are using according to any one of claims 8
Stator core.The overall weight that can reduce motor reduces batch electricity since the stator core quality of use is more stable and reliable
The level of noise of machine installation, effectively improves motor quality.
The utility model has the advantages that the one-step shaping of excircle orientation and inner hole punching may be implemented by " L " type opening slot structure, improve
Components precision reduces motor noise；Side is positioned by the positioning arc and straight line of circular arc, the circle of motor or more end cap may be implemented
Zhou Dingwei improves assembly efficiency；By the trimming structure of stator punching appearance profile, overall size is not only reduced, and can
To realize cross arrangement of the stator punching in punch die, lifting process is arranged effect, and stock utilization is improved, reduce motor at
This.
