[0002] Traditional motors often use the method of pouring lubricating oil on one side of the motor bearing for bearing lubrication. However, the bumps and vibrations of the motor during operation will easily cause the lubricating oil to splash into the air gap between the rotor and the stator, resulting in stator damage. The indirect connection between the rotor and the rotor increases the friction loss between the stator and the rotor, which not only leads to additional energy loss and reduces the efficiency of the motor, but also causes the temperature of the stator and rotor to be too high due to frictional heat, which damages the motor
The traditional air-cooled motor is to open holes in the motor shell, and the rotor rotates to drive the fan blades to generate convection to cool down. However, this will intensify the liquid splashing inside the motor, and the high-voltage motor usually needs to adopt a sealed structure and cannot open holes. Only water cooling or oil cooling can be used, instead of air cooling for auxiliary cooling

Embodiment 1
[0027] In Embodiment 1 and Embodiment 2, the baffle (10) is fixed on the blade (9) in two different ways, and in order to make the baffle (10) more firmly fixed, the baffle (10) can also be fixed at the same time It is fixed on the fan blade (9) by embedding and screwing, and it is only a simple combination of embodiment 1 and embodiment 2, which is easily understood by those skilled in the art, so I won't go into details here.
[0028] In embodiment 1 and embodiment 2, the baffle (10) is fixed on the fan blade (9) on the side of the first bearing (7); and the baffle (9) is fixed on the second bearing (8) One side of the fan blade and the fan blade (9) that fixes the baffle (10) to the side of the first bearing (7) are also feasible. In fact, in actual use, it depends on which side of the bearing is poured with lubricating oil. Fix the baffle (10) on the fan blade on one side. The baffle (10) is fixed on the blade (9) on the side of the second bearing (8) compared to the bla...

The invention discloses an air cooling motor. The air cooling motor comprises an annular baffle (10), wherein the baffle (10) is fixedly arranged on a blade (9) at certain side of a rotor (3); the rotor (3) is annular, a rotor bracket (13) is arranged between the inner annular surface of the rotor (3) and a rotating shaft (6) and provided with a plurality of hollowing holes (14) which axially penetrate through the rotor bracket (13); the baffle (10) is not contacted with the rotating shaft (6), and the radius of an outer ring of the baffle (10) is smaller than that of the outer ring of the rotor (3). The invention aims at overcoming the defects of the traditional motor, and provides an air cooling motor structure which is simple in structure, and capable of improving the cooling effect, reducing the weight of the motor and preventing bearing oil at certain side from splashing into a gap between the rotor (3) and a stator (2).
Description
technical field [0001] The invention belongs to the field of motor air-cooling, and in particular relates to an air-cooling motor adopting a structure in which a single-side fan blade fixes a baffle. Background technique: [0002] Traditional motors often use the method of pouring lubricating oil on one side of the motor bearing for bearing lubrication. However, the bumps and vibrations of the motor during operation will easily cause the lubricating oil to splash into the air gap between the rotor and the stator, resulting in stator damage. The indirect connection between the rotor and the rotor increases the friction loss between the stator and the rotor, which not only leads to additional energy loss and reduces the efficiency of the motor, but also causes the temperature of the stator and rotor to be too high due to frictional heat, which damages the motor . The traditional air-cooled motor is to open holes in the motor shell, and the rotor rotates to drive the fan blade...
