Abstract
The utility model relates to a motor housing equipped with heat dissipating holes. The motor housing comprises a housing body. A positioning hole is disposed on the center of the rear end cover of the housing body. More than one heat dissipating hole is disposed on the end face of the rear end cover of the housing body. The heat dissipating holes are communicated with the inner chamber of the housing body. Rubber air doors used for controlling the heat dissipating holes to be opened or closed are disposed in the heat dissipating holes. The heat dissipating holes disposed on the rear end cover enables an operating motor to be capable of automatically opening an air exhaust to dissipate heat outwardly. The air exhaust can be automatically closed when the motor is static so as to ensure an advantage of enclosed waterproof performance of the motor. As a result, the operating temperature of the motor is basically at positive temperature a little more than normal temperature so that the stability of the effective output power of the motor is guaranteed.
Description
Technical field
The utility model relates to a kind of motor case with louvre.
Background technology
Original motor casing rear end lid is not have the air discharging and radiating function, be that the motor internal temperature swashs acute the rising along with the growth of machine operation time after the machine operation, the rotor of motor High Rotation Speed produces reverse high temperature damping wind speed eddy current, the wind speed impedance of rotor is increased rapidly, the wire diameter temperature of motor coil also swashs acute the rising simultaneously, cause the wire diameter resistance of coil inside to raise, effective power reduces, sharply increase in large quantities the reactance capacity of motor with the form of heating, if during the technique defectiveness of other positions, particularly the rosin joint of each pad exposes short circuit or the fault such as open circuit more, causes scorification electrical fault rate and motor not to turn the shortcomings such as raising of failure rate.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of motor case with louvre is provided, motor can automatically be opened in the running outside exhaust outlet and outwards dispel the heat, and has guaranteed the stability of the effective output of motor.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor case with louvre, comprise casing ontology, the middle part of the rear end cap of described casing ontology is provided with location hole, also be provided with the louvre more than 1 on the end face of the rear end cap of described casing ontology, described louvre communicates with the inner chamber of casing ontology, is provided with the rubber air door that opens and closes for the control louvre in the described louvre.
Further, the quantity of described louvre is 8, and described 8 louvres are circumferentially uniform around location hole on rear end cap.
The beneficial effects of the utility model are: the utility model provides a kind of motor case with louvre, at rear end cap louvre is set, making motor can automatically open in the running outside exhaust outlet outwards dispels the heat, can the autoshutdown exhaust outlet when motor is static, guarantee the advantages such as sealing water resistance of motor.So, the working temperature of motor is under the positive temperature a little more than normal temperature substantially works, guaranteed the stability of the effective output of motor, also reduce simultaneously motor High Rotation Speed rotor and produced reverse high temperature impedance wind speed eddy current, improve the effective output of motor, guaranteed to have improved the conforming advantage of the every technical parameter of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 be electric machine casing partly cut open structural representation;
Wherein: 1, casing ontology, 2, louvre.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of motor case with louvre, comprise casing ontology 1, the middle part of the rear end cap of casing ontology 1 is provided with location hole, also be provided with 8 louvres 2 on the end face of the rear end cap of casing ontology 1, louvre 2 communicates with the inner chamber of casing ontology 1, is provided with the rubber air door that opens and closes for control louvre 2 in the louvre 2, and 8 louvres 2 are circumferentially uniform around location hole on rear end cap.
At rear end cap louvre 2 is set, makes motor can automatically open in the running outside exhaust outlet and outwards dispel the heat, can the autoshutdown exhaust outlet when motor is static, guarantee the advantages such as sealing water resistance of motor.So, the working temperature of motor is under the positive temperature a little more than normal temperature substantially works, guaranteed the stability of the effective output of motor, also reduce simultaneously motor High Rotation Speed rotor and produced reverse high temperature impedance wind speed eddy current, improve the effective output of motor, guaranteed to have improved the conforming advantage of the every technical parameter of motor.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (2)
