Description

Technical Field

[0001] The utility model belongs to the field of motors, and in particular relates to a high-temperature resistant motor. Background Art

[0002] The operating temperature of the motor has a great influence on the stability of the motor operation. Higher temperature will have a great impact on the stability of the internal circuit transmission of the motor, the aging status of the materials, the lubrication effect of the bearing grease, etc. The motor itself will generate more heat during operation. At this time, if the motor cannot discharge the heat in time, the heat generated by the operation will accumulate and cause the motor to run in a high temperature state, which will reduce the operating performance of the motor, shorten the service life of the motor, and have a higher safety hazard. The current motor heat dissipation method is mostly to set an air outlet at the tail of the motor, and a impeller is set in the air outlet. The impeller rotates with the shaft to discharge the heat of the motor outward. However, the front end of the motor currently used is mostly closed, and it is difficult for the impeller to form air flow to cool the inside of the motor, and the heat dissipation effect is poor.

[0006] Furthermore, a second air outlet is provided at a connection position between the main body and the front end cover relative to the heat sink; and an edge position of the second fan blade is opposite to the second air outlet.

[0007] Furthermore, the front end cover is provided with a slide groove at a position relative to the air inlet; a dust filter is slidably provided in the slide groove.

[0013] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a high temperature resistant motor of the present invention in conjunction with the accompanying drawings.

[0014] like Figure 1-3 As shown, the utility model is a high-temperature resistant motor, including a main body 1; a front end cover 2 is provided at one end of the main body 1; a rotor 3 is rotatably provided in the main body 1; a stator 4 is provided on the inner wall of the main body 1; a rotating shaft 5 is provided in the rotor 3 and extends to the outside of the front end cover 2; a first air outlet 6 is provided at one end of the main body 1 away from the front end cover 2; an air inlet 7 is provided on the outside of the rotating shaft 5 of the front end cover 2; a first fan blade 8 is provided on the rotating shaft 5 near the first air outlet 6 in the main body 1; a second fan blade 9 is provided on the rotating shaft 5 near the air inlet 7 in the front end cover 2; a plurality of heat sinks 10 are provided on the outside of the main body 1; and a base 11 is provided on the lower side of the main body 1.

[0015] Combine Figure 1-3 As shown, during use, the motor is started, and as the rotor 3 and the shaft 5 rotate, the first fan blade 8 and the second fan blade 9 rotate with the motor shaft 5 to supply air and generate negative pressure, and the air at normal temperature outside is introduced into the air inlet 7 set at the front end cover 2, and is transported through the main body 1 by the first fan blade 8 and the second fan blade 9, and the high-temperature heat in the main body 1 is carried out and discharged through the first air outlet 6 set in the main body 1, effectively reducing the internal temperature of the motor, maintaining stable operation of the motor under high temperature state, and avoiding performance degradation or failure caused by excessive temperature. The first fan blade 8 and the second fan blade 9 rotate synchronously to form a connected ventilation channel on both sides of the main body 1, accelerate the air flow, quickly bring out the heat generated inside the main body 1, and increase the heat dissipation efficiency.

[0016] A second air outlet 12 is provided at the connection position between the main body 1 and the front end cover 2 relative to the heat sink 10; the edge position of the second fan blade 9 is opposite to the second air outlet 12, and a heat sink 10 is provided on the outside of the main body 1. The heat sink 10 conducts the heat of the main body 1 to the heat sink 10 itself, and increases the heat exchange area with the outside air through the heat sink 10 to dissipate heat and cool down. When the second fan blade 9 rotates with the rotating shaft 5, a part of the wind delivered is discharged through the second air outlet 12 and blows to the heat sink 10, carrying away the heat conducted from the main body 1 by the heat sink 10 relative to the second air outlet 12, thereby increasing the effect of the heat sink 10 on the heat conduction of the main body 1, and cooperating with the internal ventilation and cooling of the main body 1 to form a synchronous heat dissipation and cooling of the inside and outside of the main body 1, thereby increasing the overall cooling effect of the main body 1.

[0017] The front end cover 2 is provided with a slide groove 13 at a position relative to the air inlet 7; a dust filter 14 is slidingly provided in the slide groove 13, and the dust filter 14 is slidingly provided in the slide groove 13 provided on the front end cover 2 relative to the air inlet 7. The air entering the main body 1 through the air inlet 7 is filtered by the dust filter 14 to prevent dust and impurities in the air from entering the internal space of the main body 1, thereby extending the service life of the motor and avoiding dust clogging the first air outlet 6 or the second air outlet 12, thereby affecting the heat dissipation effect of the motor. After the dust filter 14 has been used for a certain period of time to filter a certain amount of dust and impurities, the dust filter 14 is slid out of the slide groove 13 for cleaning or replacement. The operation is convenient to prevent the air inlet 7 from being blocked.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
