Abstract
The utility model discloses an air outlet channel of a motor, and the air outlet channel is applied to the technical field of high-speed-regulation-ratio direct-current motors. The air outlet channel comprises a left end cover and a right end cover, wherein a motor stator is arranged between the left end cover and the right end cover, the upper end face of the left end cover is provided with an air inlet, and the upper end face of the right end cover is provided with a first air outlet and a second air outlet; an air deflector is arranged in the right end cover and between the first air outlet and the second air outlet, and the upper end of the air deflector is connected to the right end cover; and the air deflector inclines toward the stator. The air outlet channel provided by the utility model has the advantages that because the right end cover with the air deflector and two air outlets is adopted, a two-way air outlet channel of the motor is formed, thereby achieving the effective heat dissipation of the motor, preventing the occurrence of motor faults caused by delayed heat dissipation and further ensuring the normal operation of the motor.
Description
Technical field
The utility model relates to a kind of high speed ratio DC motor, relates in particular to a kind of motor air-out passage.
Background technology
High speed ratio DC motor needs heat radiation in the running, air inlet and air outlet is set on motor casing usually realizes its heat radiation.
Common high speed ratio DC motor, interval motor stator and rotor between air inlet and air outlet, most of by the air intake that air inlet enters through behind stator and the rotor, discharge from air outlet.The components and parts such as brush holder in the motor and commutator that are arranged so that like this can not get sufficient heat radiation, make that the radiating effect of motor is not good, easily cause the motor operation troubles.
A kind of motor air-out passage need be provided, realize the efficiently radiates heat of motor, prevent motor, thereby guarantee the normal operation of motor because of untimely the breaking down of dispelling the heat.
The utility model content
Technical problem to be solved in the utility model provides a kind of motor air-out passage, realizes the efficiently radiates heat of motor, guarantees the normal operation of motor, because of can not in time dispelling the heat the defective of operation troubles takes place thereby overcome in the prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of motor air-out passage, comprise left end cap and right end cap, has motor stator between left end cap and the right end cap, the upper surface of left end cap has air inlet, the upper surface of right end cap has first air outlet and second air outlet, be connected the wind deflector on the right end cap on having between first air outlet and second air outlet in the right end cap, wind deflector tilts to the stator direction.
In the utility model preferred implementation, wind deflector extends downward near motor armature.
Adopt the beneficial effect of technique scheme:
The right end cap with wind deflector and two air outlets that the utility model adopts makes motor field frame inside form the first air-out passage of motor between stator, rotor, wind deflector and first air outlet, realizes the heat radiation of stator, rotor; Motor field frame inside forms the second air-out passage of motor between rotor, wind deflector and second air outlet, realize the heat radiation of commutator for electric motor and brush holder, prevents motor because of untimely the breaking down of dispelling the heat, thereby guarantees the normal operation of motor.
Description of drawings

Embodiment
Below in conjunction with specific embodiment the utility model is further described:
See also Fig. 1, it is a structural representation of the present utility model, and high speed ratio DC motor mainly comprises stator 010, is arranged on the rotor 020 of stator 010 inside, is arranged on the armature 030 between stator 010 and the rotor 020.
High speed ratio DC motor shell mainly comprises left end cap 040 and right end cap 050.Stator 010 is arranged between left end cap 040 and the right end cap 050.The left end cap 040 and right end cap 050 outside are respectively arranged with first member plate and right end plate, and the rotating shaft of rotor 020 is arranged in the seam of first member plate and right end plate by bearing.
The upper surface of left end cap 040 is provided with motor air inlet 041, and the upper surface of right end cap 050 is provided with the motor air outlet, and air outlet has 2: first air outlet 051 and second air outlet 052.Have wind deflector 053 on the right end cap intracavity sidewall between first air outlet 051 and second air outlet 052, wind deflector 053 tilts in the horizontal direction and extends to the upper surface of motor armature 030.
The wind deflector 053 on the right end cap 050 and first air outlet 051 and second air outlet 052, make motor field frame inside between stator 010, rotor 020, wind deflector 053 and first air outlet 051, form the first air-out passage of motor, realize the heat radiation of stator 010, rotor 020; Motor field frame inside forms the second air-out passage of motor between rotor 020, wind deflector 053 and second air outlet 052, realize the heat radiation of commutator for electric motor and brush holder, prevent motor because of untimely the breaking down of dispelling the heat, thereby guarantee the normal operation of high speed ratio DC motor.
Above-mentioned embodiment is exemplary; be in order better to make those skilled in the art can understand this patent; can not be interpreted as it is restriction to this patent protection range; so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
