Description
Technical field
The invention belongs to low-power machine fields, and in particular to a kind of rotor design of switched reluctance machines.
Background technique
Switch reluctance machine rotor includes shaft, rotor core and dynamic balance weight, and switch reluctance machine rotor iron core is silicon
Steel disc.For the rotor to run at high speed, influence of the amount of unbalance for motor noise, service life is all very big.Due to silicon steel
Piece end face is done dynamic balancing and be can not be achieved, so needing special designing dynamic balancing auxiliary device to realize the dynamic balancing of entire rotor
It is required that present dynamic balance weight generally is annulus made of iron, method when duplicate removal is the side for drilling, and drilling on annulus
Position, size and depth rely on the working experience of worker more；Existing annulus made of iron is simultaneously for the demand that balances now, annulus
Thickness is very thick, to affect the length of motor manufacturing, is not able to satisfy the production of high-precision motor.
Summary of the invention
In order to overcome drawbacks described above, the purpose of the present invention is to provide a kind of switched reluctance machines, by dynamic balancing
The design of block effectively reduces rotor axial distance, shortens motor effective length, while improving the production efficiency of motor
And operational efficiency.
To achieve the goals above, the technical solution of the present invention is as follows:
A kind of switched reluctance machines, are equipped with rotor, and the rotor includes the dynamic of shaft, rotor core and setting rotor core both ends
Balance weight, the rotor core side are formed with the rotor slot and rotor tooth of several bumps, and the dynamic balance weight includes one knot
Ontology, ridge and several claws of structure, several claws are located on the end face that balance block body is docked with rotor core, described
Claw quantity, position are corresponding with the rotor slot number, position that rotor core is formed respectively, the rotor core side and dynamic balance weight
Between realized and connect by the interference fit of claw and rotor slot；The ridge is located at the back of the dynamic balance weight opposite with claw
Face is at least eight reinforcing ribs circumferentially uniformly distributed centered on shaft.
As a further improvement of the present invention: the dynamic balance weight is made of brass material.Due to the density ratio one of brass
As metal want high, the thickness of balance weight can be reduced；Furthermore for duplicate removal method technique, brass is easier to realize, and brass
Production efficiency is relatively high, reduces manufacturing cost.Still further aspect causes rotor moment of inertia to compare since brass density is higher
Greatly, there is facilitation for motor quick response.
As a further improvement of the present invention: the axial width of the claw is the 15-20% of rotor core axial length,
It reduces while reinforcing claw and being connected with rotor core rotor slot on the interference of rotor core and influence.
As a further improvement of the present invention: being coated with glue on the claw and rotor slot connecting end surface, prevent motor
Balance weight falls off in high-speed rotation process.
As a further improvement of the present invention: several loss of weight sections are formed by processing sectional grooves on the reinforcing rib, it is convenient
With specification duplicate removal.
The present invention passes through the cooperation of claw and motor rotor core rotor slot, avoids motor and puts down in high-speed rotation process
The problem of weighing apparatus block falls off.Claw extends towards iron core direction simultaneously, increases balance weight weight, can effectively reduce balance block body
Thickness shorten motor effective length to reduce rotor axial distance.In addition both ends balance weight can play simultaneously tight simultaneously
Rotor punching prevents discrete piece defect axially occur.
The present invention after testing, can effectively improve the stacking factor 3% or so of iron core, improve motor operation efficiency about 2-5%.
The production efficiency of motor can be improved simultaneously.

Specific embodiment
In order to make those skilled in the art be better understood on technical solution of the present invention, with reference to the accompanying drawing 1
It is further described with 2 pairs of technical solution of the present inventions.
Embodiment
The present embodiment is related to small power switch reluctance motor, including stator and rotor.Rotor includes shaft as shown in Figure 1:
1, the dynamic balance weight 2 of rotor core 3 and setting rotor core both ends；Wherein 3 length of rotor core is 28mm, and 1 diameter of shaft is
9mm.There are four concave-convex rotor slot 31 and rotor tooths 32 for the formation of rotor core side.
Ontology 21, ridge and four claws 22 of the dynamic balance weight 2 including integral structure as shown in Figure 1:, four claw 22
In on the end face that balance block body 21 is docked with rotor core 3.When connection, first in both four claws, 22, four rotor slots 31
Interface on glue is respectively coated, then by both interference fit realize that the fixed of rotor core 3 and dynamic balance weight 2 connects
It connects.As shown in Figure 2: ridge design is to have eight on the end face opposite with 22 position of claw at the back side of dynamic balance weight ontology 21
Reinforcing rib 23 forms, and eight reinforcing ribs 23 centered on shaft 1 and are circumferentially uniformly distinguished.
In the present embodiment, the entire dynamic balance weight 2 is made of brass, and wherein the axial width of claw 22 is 5mm.
As shown in Fig. 2, every reinforcing rib 23 has certain thickness and width, processing sectional grooves are divided equally on reinforcing rib 23
231, the consistent loss of weight section of several grammes per square metres is formed, the grammes per square metre of loss of weight section calculates according to the design needs, according to the side of detection when duplicate removal
Position and loss of weight amount, folder removes corresponding loss of weight section, convenient, practical and quick, improves production efficiency.
The present embodiment after testing, can effectively improve the stacking factor 3% of iron core, improve motor operation efficiency about 2.8%.
Basic principles and main features and advantage of the invention have been shown and described above.But the foregoing is merely this hairs
Bright specific embodiment, technical characteristic of the invention are not limited thereto, therefore any those skilled in the art is not departing from this
The other embodiments obtained under the technical solution of invention should all cover within the scope of the patent of the present invention.
