Abstract
The utility model relates to a switched reluctance motor slot wedge mounting structure. The utility model discloses the structure of taking does: including motor stator (1), slot wedge (2), groove facade (3), groove plane (4), stator tooth (5). Slot wedge mounting structure is close to air gap department on motor stator tooth (5), have two slot wedge mounting grooves on every motor stator tooth (5), and the bilateral symmetry distribution, the slot wedge mounting groove comprises groove facade (3), groove plane (4), and groove facade (3) of two slot wedge mounting grooves in the same motor stator groove are parallel planes, and same motor stator groove two groove plane (4) are the verticallies with this motor stator groove central line. This structure is when guaranteeing that the motor performance is not influenced, and the motor slot wedge easily takes off the groove problem when effectively having solved the switched reluctance motor operation, is particularly suitable for big notch class motor field.
Description
Technical field
The utility model belongs to a kind of Stators for Switched Reluctance Motors structure-design technique.
Background technology
Switched reluctance machines has that structure is simple, cost is low, fault-tolerance is good, power density advantages of higher, and can conveniently realize starting and generating electricity pair function by changing controling parameters; At present, what switched reluctance machines was got more and more uses in aircraft telex system, and it is at civilian use electric car, and the fields such as coal factories and miness are also widely used.
But traditional switch reluctance motor stator slot wedge installs structure, there is following problem:
1, owing to the Stators for Switched Reluctance Motors number of teeth is less, being generally 6,8,12, due to machine operation mechanism, motor slot is generally wider, compares the boss lacking motor slot wedge with induction motor and installing; Easily come off so traditional Stators for Switched Reluctance Motors slot wedge is installed, if air gap fallen into by slot wedge can damage motor;
2, due to switched reluctance machines self electromagnetism constructional feature, motor torque ripple is relatively big, and motor vibrations are relatively big, and firmly slot wedge installation structure is most important to the steady running of motor.
Practical novel content
The purpose of this utility model is: proposes a kind of switched reluctance machines slot wedge and installs structure, designs slot wedge and install groove, while not affecting motor performance, it is possible to solve the problem that switched reluctance machines slot wedge easily comes off on motor stator.
The technical scheme that the utility model is taked is: structure installed by described slot wedge is close air gap place on motor stator tooth 5, each motor stator tooth 5 has two slot wedges install grooves, and symmetrical distribution, and described slot wedge is installed groove and is made up of groove facade 3, groove plane 4; And same motor stator slot two slot wedges groove facade 3 of installing grooves is parallel plane, same motor stator slot two groove planes 4 are vertical with this motor stator slot medullary ray.
Preferably, the width of groove plane 4 is determined by the width of motor stator tooth;
Preferably, groove installed by the width of slot wedge 2 and the slot wedge of motor stator is transition fit.
The advantage that the utility model has is: structure installed by this slot wedge, solves the installation of Stators for Switched Reluctance Motors slot wedge and easily comes off, and the problem that air gap damages motor fallen into by slot wedge.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model better embodiment;
Wherein, 1: motor stator, 2: slot wedge, 3: groove facade, 4: groove plane, 5: stator tooth
Embodiment
Being elaborated by the utility model below in conjunction with Figure of description, see Fig. 1, structural representation installed by a kind of switched reluctance machines slot wedge of the utility model. Described it is made up of motor stator 1, slot wedge 2, groove facade 3, groove plane 4, motor stator tooth 5. Diagram switched reluctance machines is 12/8 structure, and the motor stator number of teeth is 12, and motor tooth is parallel teeth. Motor stator outer diameter 110mm, motor facewidth 7mm, motor tooth pitch 15mm, near air gap place on motor stator tooth, each motor stator tooth has the slot wedge of two install groove, and symmetrical distribution, and described slot wedge is installed structure and is made up of groove facade 3, groove plane 4; And the groove facade 3 of installing grooves of two slot wedges in same groove is parallel plane, distance 10mm, two groove planes in same groove are vertical with groove center line. Groove plane width 1mm, slot wedge thickness 2mm, slot wedge width 10mm, and be transition fit with slot wedge installation groove.
The utility model achieves switched reluctance machines slot wedge and installs structure, takes and processes the mode that groove installed by slot wedge on the stator teeth, and preventing switched reluctance machines to run is that slot wedge comes off problem; And the width of suitable groove plane does not affect the electromagnetic performance of motor.
