Abstract
Built -in rotor subassembly of fan blade belongs to motor technical field, and including pivot, rotor core, commutator that the cooperation is connected, rotor core, commutator cup joint in proper order in the pivot, and the cooperation sets up the fan blade subassembly between its characterized in that rotor core and the commutator, and the connection of fan blade subassembly sets up on rotor core, built -in rotor subassembly of fan blade, and novel in design, and reasonable in structure, make full use of the technology hole installation fan blade subassembly between rotor core and the commutator, can obviously shorten the axial length of motor, save motor installation space and make material cost, the use occasion of extension series excited machine, the fan blade subassembly is arranged in between rotor core and the commutator simultaneously, can obviously improve the result of ventilating heat dissipation of motor, obviously reduce the motor temperature rise under the equal operation condition, the efficiency of the use of motor is improved, and the service life of the motors can be prolonged.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of fan blade built-in rotor assembly being mainly applicable to series excited machine.
Background technology
The rotor assembly of series excited machine substantially comprises rotor and is serially connected in epitrochanterian rotor core, commutator, fan blade part successively, fan blade part needs certain installing space, increase the axial length of motor, limit the use occasion of motor, and fan blade part is mounted in the outer end of commutator, with rotor core apart from distant, the ventilating and cooling effect of rotor core and correspondent section rotating shaft can be had influence on, electric machine temperature rise is obvious, affects service efficiency and the life-span of motor.In addition, there is technique space between commutator and rotor core, and any parts are not installed at this position, therefore in traditional rotor component construction, this part space wastes.
Utility model content
The utility model aims to provide a kind of fan blade built-in rotor component technology scheme with fan blade embedding structure, to overcome problems of the prior art.
Described fan blade built-in rotor assembly, comprise be connected rotating shaft, rotor core, commutator, rotor core, commutator are socketed in rotating shaft successively, it is characterized in that being equipped with fan blade assembly between rotor core and commutator, and the connection of fan blade assembly is arranged on rotor core.
Described fan blade built-in rotor assembly, it is characterized in that described fan blade assembly comprises and install pin and air blade, air blade adopts centrifugal structure, installs pin and coordinates with rotor core grafting.
Described fan blade built-in rotor assembly, is characterized in that described fan blade assembly is installed and is connected in the iron core notch of rotor core.
Described fan blade built-in rotor assembly, is characterized in that described installation pin circumference is symmetrical arranged more than three or three.
Above-mentioned fan blade built-in rotor assembly, novel, rational in infrastructure, the technique hole taken full advantage of between rotor core and commutator installs fan blade assembly, obviously can shorten the axial length of motor, save motor mounting space and manufactured materials cost, the use occasion of expansion series excited machine, fan blade assembly is placed between rotor core and commutator simultaneously, obviously can improve the result of ventilating heat dissipation of motor, obviously electric machine temperature rise is reduced under equal operating condition, improve the service efficiency of motor, extend motor useful life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the perspective view of described built-in fan blade assembly;
Fig. 3 is the left TV structure schematic diagram of Fig. 2;
In figure: 1-rotating shaft, 2-rotor core, 2a-iron core notch, 3-fan blade assembly, 3a-install pin, 3b-air blade, 4-commutator.
Embodiment
Now in conjunction with Figure of description, describe embodiment of the present utility model in detail:
Figure 1 shows that fan blade built-in rotor assembly, rotor core 2, commutator 4 are socketed in rotating shaft 1 successively, technique aperture position between rotor core 2 and commutator 4 is equipped with fan blade assembly 3, and fan blade assembly 3 is positioned at the outside of End winding simultaneously, and is fixed on rotor core 2.This fan blade assembly 3 embedding structure takes full advantage of the technique hole between rotor core 2 and commutator 4, save fan blade installing space of the prior art, obviously can shorten the axial length of motor, save motor mounting space and manufactured materials cost, the use occasion of expansion series excited machine, fan blade assembly 3 is placed between rotor core 2 and commutator 4 simultaneously, obviously can improve the result of ventilating heat dissipation of machine shaft 1, rotor core 2, commutator 4, obviously electric machine temperature rise is reduced under equal operating condition, improve the service efficiency of motor, extend motor useful life.
In above-described embodiment, fan blade assembly 3 comprises installs pin 3a and air blade 3b, as shown in Figure 2 and Figure 3, pin 3a circumference is installed and is symmetrical arranged more than three or three, installation pin 3a is plugged in the iron core notch 2a of rotor core 2, make fan blade assembly 3 be affixed to easily on rotor core 2, air blade 3b adopts centrifugal structure, also can adopt shaft flow structure.
