Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1 and 2, a cooling device layout of a permanent magnet motor and an air path structure thereof includes an air cooler disposed inside the permanent magnet motor, a rotor 9, a stator 13, and an air path structure matching the air cooler.
The permanent magnet motor is characterized in that the inner space of the permanent magnet motor is uniformly divided into even fan-shaped spaces, an air cooler is arranged in any one of the fan-shaped spaces, and the air cooler is arranged in the space between the shaft extension end support 8 and the non-shaft extension end support 7. In the present embodiment. The interior of the permanent magnet motor is divided into 6 areas and is provided with 6 air coolers. Wherein the air cooler 1, the air cooler 3 and the air cooler 5 are non-shaft-extension-end air coolers, and air inlets of the air coolers are arranged on a non-shaft-extension-end bracket 7; the air cooler 2, the air cooler 4 and the air cooler 6 are shaft extension end air coolers, and air inlets of the shaft extension end air coolers are arranged on a shaft extension end support 8. Either air cooler opens into the rotor 9 and delivers cooled air to the rotor 9. The shaft extension end support 8 and the non-shaft extension end support 7 are provided with brushes 12, and the shaft extension end support 8, the non-shaft extension end support 7 and the rotor 9 are in rotary sealing through the brushes 12.
Radial ventilation holes are uniformly distributed in the rotor 9, the magnetic steel 10 is separated by the stainless steel 11 to form radial ventilation channels, the radial ventilation channels correspond to the radial ventilation holes one to one, and the radial ventilation channels lead to air gaps between the stator 13 and the rotor 9.
Radial wind channels of the stator are uniformly distributed on the stator 13, and the radial wind channels of the stator are arranged in a staggered mode, lead to the yoke part of the stator 13 and are communicated with the end part of the stator.
The utility model discloses a permanent-magnet machine's cooling device overall arrangement and wind path structure's concrete working method as follows: the air coolers 1, 2, 3, 4, 5, and 6 blow cooling air toward the rotor 9. Because the shaft extension end support 8 and the non-shaft extension end support 7 realize rotary sealing with the rotor 9 through the brush 12, cooling air blows to the stator 13 from the ventilation hole formed in the rotor 9 and the ventilation channel between the magnetic steels 10. Because the radial air duct of the stator 13 is staggered with the radial air duct of the rotor 9, wind can blow over the surface of the magnetic steel 10, and thus the magnetic steel 10 is cooled. Wind blows from the surface of the magnetic steel 10 to the stator radial air duct of the stator 13, so that the stator 13 is continuously cooled. After cooling the stator 13, the air is blown from the yoke of the stator 13 to cool the yoke of the stator 13, and blown to the end (shaft-extending end or non-shaft-extending end) of the stator 13 to cool the coil end. Finally, the wind returns to the shaft extension end air cooler or the non-shaft extension end air cooler from the air inlets of the shaft extension end bracket 8 and the non-shaft extension end bracket 7 again, and exchanges heat to form cold wind. This structure allows both the shaft-extended end and the non-shaft-extended end of the stator 13 to be uniformly cooled.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
