Description
Technical field
The utility model relates to magnetic-suspension linear motor field, the stator core knot of specially a kind of magnetic-suspension linear motor
Structure.
Background technique
Magnetic-suspension linear motor armature winding is installed on compartment bottom, secondary windings is layed in rail surface, wherein
For the notch of the stator core of armature winding towards rail, secondary windings is to extend and splice to be layed in rail surface along its length
Several segments aluminium sheet, spliced after train longtime running by the aluminium sheet (i.e. secondary windings) that the factors such as external force are influenced rail surface
Place is often inevitably generated tiltings, and magnetic suspension train in the process of running by relief, rail flatness, arrange
The factors such as vehicle load variation will cause the clearance distance between train and rail and change, so as to cause stator core with stick up
The aluminium sheet risen occurs directly to scratch, and aluminium sheet can be lifted off rail surface by stator core when serious, destroy track, and influence railway
Safe operation；In addition, the notch both ends angle of the stator slot of existing stator core is mostly right angle or pointed shape, when winding coil is embedding
Square or pointed shape end angle often scratch winding coil surface when entering into stator slot, to influence motor performance.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of stator core construction of magnetic-suspension linear motor, can solve
Certainly existing magnetic suspension train in the process of running magnetic suspension linear electronics stator core easily with the aluminium sheet on rail surface tilt send out
The problem of life collides and influences train operating safety.
Its technical solution is a kind of stator core construction of magnetic-suspension linear motor comprising core body, the iron core
The bottom surface of ontology is towards rail, and the bottom surface of the core body uniformly offers even number item for being embedded in winding along its length
The stator slot of coil, even number stator slot is between the elongated extension of the width direction of core body, the adjacent stator slot
Core body part forms stator teeth, it is characterised in that: the company of the two sides of the bottom surface and length direction of the core body
Connecing end is fillet or oblique angle connection.
Further, the connecting end surface in the increment face of the two sides cell wall and stator teeth of every stator slot is circular arc
Transition connection.
Further, the two sides cell wall of the stator slot is symmetrically equipped with cone tank on the position of notch.
The utility model has the beneficial effects that: the connecting pin of the two sides due to the bottom surface and length direction of core body
Portion is fillet or oblique angle connection, thus magnetic suspension train is in the process of running when the bottom end of core body encounters rail table
When the aluminium sheet in face tilts end, fillet connection, which can be slipped over gently, to tilt end and can play one to end is tilted in the process
A suppressing action, so that aluminium sheet effectively be avoided to be started by core body scratch, it is ensured that railway operation safety.

Specific embodiment
Embodiment one:
See Fig. 1, Fig. 2 and Fig. 3, a kind of stator core construction of magnetic-suspension linear motor of the utility model comprising iron core
Ontology 1, the bottom surface of core body 1 is towards rail, and L uniformly offers even number item use along its length for the bottom surface of core body 1
In the stator slot 2 for being embedded in winding coil, along the elongated extension of width direction D of core body, adjacent determines even number stator slot 2
Core body part between pilot trench 2 forms stator teeth 3, the connection of the two sides of the bottom surface and length direction of core body 1
End is that fillet 4 connects；Magnetic suspension train is in the process of running when the fillet 4 of the bottom end of core body 1 encounters rail table
When the aluminium sheet 5 in face tilts end, Fig. 4 is seen, the connection of fillet 4 can gently slip over tilting end and in the process can be to tilting end
A suppressing action is played, so that aluminium sheet effectively be avoided to be started by core body scratch, it is ensured that railway operation safety.
See that Fig. 2 and Fig. 3, the connecting end surface in the increment face 31 of the two sides cell wall 21 and stator teeth 3 of every stator slot 2 are
6 transition of circular arc connection；The two sides cell wall 21 of stator slot 2 is symmetrically equipped with cone tank 22 on the position of notch.Work as winding wire
When circle is embedded into stator slot 2 from notch, the circular arc 6 of two sides can effectively avoid scratch of the notch end to winding long loop,
Effective guiding role can be played to the insertion of winding coil again, greatly improve lower linear velocity.
Embodiment two and embodiment one the difference is that, the two sides of the bottom surface and length direction of core body 1
Connecting pin is that bevelling 7 connects.See Fig. 5, is down in the connecting pin of the two sides of the bottom surface and length direction of core body 1
Under 7 connection of oblique angle, magnetic suspension train is in the process of running when the fillet 4 of the bottom end of core body 1 encounters rail table
When the aluminium sheet 5 in face tilts end, oblique angle 7, which also can be slipped over gently, to tilt end and can play one to end is tilted in the process
Suppressing action, so that aluminium sheet effectively be avoided to be started by core body scratch, it is ensured that railway operation safety.
The specific implementation of the utility model is described in detail above, but content be only the utility model create compared with
Good embodiment should not be construed as limiting the practical range of the utility model creation.All create according to the utility model is applied
All the changes and improvements made by range etc., should still belong within the patent covering scope of the utility model.
