Above-mentioned commutatorless motor produces heat in when work by resistance, and heat will be emitted and by air cooling to the motor outside.
This cooling structure is the exchange heat between the contact-making surface of air and motor, thereby heat exchange is slower.When the motor high speed rotating or when working long hours, motor can not fully be cooled off, and then cause motor performance to descend or cause fault easily.For addressing the above problem, be provided with additional cooling devices such as cooling fan in order to cooling motor at motor internal in the prior art.
But being provided with of cooling fan can make parts and production process increase and improve cost, and motor size also inevitably increases immediately simultaneously.
Summary of the invention

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Commutatorless motor of the present invention includes the rotor core that a plurality of steel plates of insulation lamination constitute with rotor; Be adjacent to the interior week of rotor core, and along a plurality of magnet of side face direction combination; Rotating shaft in the rotatable combination of the axle center of rotor core one; Be installed on the both sides of steel plate, be used to prevent that magnet from preventing to break away from parts along what the axis direction of rotating shaft broke away from, prevent structures such as loose part and balance weight in addition in a side of steel plate.The steel plate opposite side prevent to break away from the parts, along the outstanding cooling blade that is formed with of its thickness direction one.
The present invention can also adopt following technical measures:
Described cooling blade is folding the forming in part back that prevents to break away from parts by incision.
Described cooling is radial a plurality of setting with blade along circumferencial direction.
Described cooling blade is triangular shaped.
Described cooling also can be a rectangular shape with blade.
Described cooling is the preceding curved or curved bending in back with an end of blade.
Advantage and good effect that the present invention has are:
Has the commutatorless motor of heat abstractor with in the rotor in the present invention, what constitute rotor prevents that breaking away from parts is formed with cooling fan, make its cooling performance that has improved motor, reduced parts and production process simultaneously and reduce cost, and can realize the miniaturization of motor.

Embodiment
Describe example of the present invention with reference to the accompanying drawings in detail.Fig. 3 is a commutatorless motor rotor structure stereogram of the present invention; Fig. 4 is commutatorless motor rotor profiles figure of the present invention; Fig. 5 is that the present invention has the stereogram of the commutatorless motor of heat abstractor with another example of rotor.
As shown, the present invention has in the commutatorless motor of heat abstractor, and what constitute rotor (10) prevents that breaking away from parts (19) is formed with cooling (19a 19b), thereby has improved the cooling performance of motor with blade.
Rotor (10) includes the rotor core (11) that a plurality of steel plates (12) insulation lamination of disc-shape forms; Be adjacent to the interior week of rotor core (11), and along a plurality of magnet (13) of side face direction combination; Rotating shaft parts such as (14) in the rotatable combination of axle center one of rotor core (11).
The centre of rotor core (11) is formed with the axis hole (15) that is used to insert rotating shaft (14), and its edge then respectively is through with the magnet opening (16) that is used to load magnet (13).
Be formed with rivet hole (17) between axis hole (15) and the magnet opening (16), be used to insert between the steel plate (12) that runs through the mutually insulated lamination and the rivet (18) of each steel plate (12) one secure bond.
Respectively be combined with along the axis direction of rotating shaft (14) in the both sides of steel plate (12) and prevent to break away from parts (19) and to prevent loose part (20), be used to prevent that magnet (13) is loosening and break away from along the axis direction of rotating shaft (14).One side of steel plate (12) also is combined with balance weight (21).
In addition, prevent to break away from and be provided with cooling in the parts (19) (19a 19b), is used for forced circulation motor ambient air and with its cooling with blade.(19a 19b) prevents to break away from along above-mentioned that parts (19) thickness direction one is outstanding forms with blade in cooling.
That is, (19a is to prevent that the part that breaks away from parts (19) from forming by incisions such as Sheet Metal Forming Technology back is folding 19b), and it is shaped as triangle (19a) or rectangle (19b), also can be multiple difformity with blade in cooling.
(19a, end 19b) is curved for the preceding curved or back that forms with the certain curvature bending, makes its cooling performance maximization with blade in cooling.
Wherein, and preceding curved expression cooling blade (19a, end portion 19b) is to the direction of rotation bending; (19a, end portion 19b) is to the reverse rotational direction bending with blade in back curved then expression cooling.
Can find out that by accompanying drawing (19a 19b) is formed at a side that prevents to break away from parts (19), promptly is formed at a side of rotor core (11), but also can together be formed in the balance weight (21) of its opposition side with blade in cooling.
Thereby (19a 19b) prevents that magnet (13) breaks away from along the axis direction of rotating shaft (14), has played the effect of cooling fan, the heat that is produced in the time of effectively distributing machine operation simultaneously with blade in cooling.
