Abstract
The invention discloses a brushless drive motor rotor, which comprises a plurality of steel sheets which are overlapped with each other, wherein dovetail grooves are uniformly distributed at the periphery of the steel sheets along the peripheral direction; the dovetail grooves of the plurality of steel sheets are in alignment along the axial direction; the dovetail grooves of the plurality of steel sheets are overlapped to form a relatively long dovetail-shaped through slot; a magnetic shoe is embedded into the dovetail-shaped through slot; by replacing a magnetic shoe adhesive structure with the dovetail groove fixed magnetic shoe structure, the magnetic shoe is detachable and is easy for assembly; in addition, through reasonably selecting the material of the steel sheet, the magnetic conductivity of the rotor can also be increased, and the work efficiency of a motor is improved; and by means of holes and keys arranged at the central part of the steel sheets, an output shaft can be conveniently mounted at the central part of the rotor, thus facilitating power output.
Description
Technical field
The present invention relates to motor component, particularly a kind of motor rotor part.
Background technology
Realize in mechanical energy and the mutual transfer process of electric energy at motor; The parts that play crucial and pivotal role are referred to as armature; The armature of existing motorcycle DC drive motors is a rotor, and existing rotor is formed by coil winding usually, and coil needs the external cord energising; Will guarantee under the situation that rotor continues to rotate that the reliability of energising has caused rotor structure complicated, manufacturing is had relatively high expectations.Moreover existing magnetic shoe normally is bonded in the rotor periphery, and bonding way causes magnetic shoe on-dismountable, and firmly degree is not enough.
To above-mentioned deficiency, need to improve to existing rotor, make its no coil, be convenient to manufacturing, in addition, also make magnetic shoe more easy fixation in rotor periphery and fixation.
Summary of the invention
In view of this, the present invention provides a kind of no brush drive motor rotor, and this rotor does not have coil, has the special fixedly structure of magnetic shoe, solves existing rotor structure complicacy and is not easy to make and the non-removable technical problem of magnetic shoe.
The present invention solves the problems of the technologies described above through following technological means:
No brush drive motor rotor of the present invention comprises a plurality of overlapped steel discs, and said steel disc periphery is along circumferentially being evenly equipped with dovetail groove, and the dovetail groove of said a plurality of steel discs aligns vertically, and said dovetail groove is embedded with magnetic shoe.
Further, the zone between adjacent dovetail groove is provided with expansion hatch on the said steel disc.
Further, said steel disc is that steel below No. 10 or No. 10 is processed by the trade mark.
Further, said steel disc middle part is provided for the through hole that machine shaft passes, and through hole is provided with radially to projecting inward key, and the key of said a plurality of steel discs aligns vertically.
Further, said steel disc is provided with lightening hole.
Beneficial effect of the present invention: no brush drive motor rotor of the present invention, comprise a plurality of overlapped steel discs, said steel disc periphery is along circumferentially being evenly equipped with dovetail groove; The dovetail groove of said a plurality of steel discs aligns vertically, and the dovetail groove of a plurality of steel discs overlaps to form long swallow-tail form groove, and said swallow-tail form groove is embedded with magnetic shoe; With dovetail groove fixedly the structure of magnetic shoe replace the bonding structure of magnetic shoe, make magnetic shoe detachable, be convenient to assembling; In addition, the material of choose reasonable steel disc also can increase the permeability of rotor, improves the operating efficiency of motor; Through being arranged on the hole and the key at steel disc middle part, can easily output shaft be installed in the rotor middle part, be convenient to output power.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below will combine accompanying drawing that the present invention is elaborated, as shown in the figure: the no brush drive motor rotor of present embodiment comprises a plurality of overlapped steel discs 1; Said steel disc 1 periphery is along circumferentially being evenly equipped with dovetail groove 2, and the dovetail groove 2 of said a plurality of steel discs 1 aligns vertically, the dovetail groove 2 common dovetail grooves that form than length of a plurality of steel discs; Magnetic shoe 3 is embedded in this long dovetail groove; Compare with bonding way, be easy to assembling and dismounting, and more solid and reliable.
Further improvement as technique scheme; Zone on the said steel disc 1 between adjacent dovetail groove 2 is provided with expansion hatch 7, through in expansion hatch, inserting the column nail, can make expansion hatch produce a certain amount of distortion; Thereby tighten up dovetail groove, to firmly fix magnetic shoe more.
As the further improvement of technique scheme, said steel disc 1 is that steel below No. 10 or No. 10 is processed by the trade mark, can increase the permeability of rotor, improves magnetic field, improves motor working efficiency.
Further improvement as technique scheme; Said steel disc 1 middle part is provided for the through hole 4 that machine shaft passes; Through hole 4 is provided with radially to projecting inward key 5; The key 5 of said a plurality of steel disc 1 aligns vertically, can the output shaft that have keyway be installed in the through hole to export, and is simple and reasonable.
As the further improvement of technique scheme, said steel disc 1 is provided with lightening hole 6, alleviating the weight of rotor, thereby alleviates motor weight.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
