Embodiment 1
[0039] Such as Figure 2-Figure 7 As shown, the present invention provides a rotor assembly 10, comprising:
[0040] The rotor core 11, the middle part of the rotor core 11 is provided with a first shaft hole 111, and a plurality of salient poles 112 are uniformly distributed on the side, and a gap penetrating through both ends of the rotor core 11 is formed between two adjacent salient poles 112. Through groove 113;
[0041] the rotating shaft 12 passing through the first shaft hole 111;
[0042] The fan blade 13 is arranged at one end of the rotor core 11, and the fan blade 13 is provided with a plurality of first one-to-one corresponding to the through slot 113 and inserted into the through slot 113 toward the side of the rotor core 11. A boss 131, the first boss 131 is surrounded by the inner wall of the through groove 113 to form a first accommodation chamber 14;
[0043] The shading plate 15 is arranged at the other end of the rotor core 11, and the shading plate 15 i...
Embodiment 2
[0057] Such as figure 2 , image 3 As shown, in an alternative embodiment of the present invention, there is a gap between the first boss 131 and the second boss 151 that are oppositely disposed.
[0058] The first boss 131 and the second boss 151 that are arranged oppositely refer to the first boss 131 and the second boss 151 that are arranged in the same through groove 113, and the first boss 131 that is arranged oppositely and the second boss 151 A gap is left between the tables 151 , and the gap can be used as an operating space, and the counterweights are loaded into the first receiving chamber 14 and / or the second receiving chamber 16 through the gap.
Embodiment 3
[0060] Such as Figure 2-Figure 7 As shown, in an optional embodiment of the present invention, the distance between the first boss 131 and the shaft centerline of the rotating shaft 12 is equal, and the distance between the second boss 151 and the shaft centerline of the rotating shaft 12 The distances are equal.
[0061] Specifically, both the first boss 131 and the second boss 151 are arc-shaped. Certainly, the first boss 131 and the second boss 151 can also be sheet-like plates or other shapes. The first bosses 131 are arranged around the axis centerline of the rotating shaft 12, and the second bosses 151 are arranged around the axis centerline of the rotating shaft 12, so that all the first bosses The centerline distances between the platforms 131 and the rotating shaft 12 are equal, and the distances between all the second bosses 151 and the centerlines of the rotating shaft 12 are equal.
[0062] The distances between the first boss 131 and the shaft centerline of th...

Abstract
The invention is suitable for the field of motors, and provides a rotor assembly and a switched reluctance motor. The rotor assembly comprises: a rotor iron core; a rotating shaft; fan blades provided with a plurality of first bosses which correspond to the through grooves in a one-to-one mode and are inserted into the through grooves, wherein the first bosses and the inner walls of the through grooves define a first containing cavity; a shading plate provided with a plurality of second bosses which are in one-to-one correspondence with the through grooves and are inserted into the through grooves, wherein the second bosses and the inner walls of the through grooves are enclosed to form a second accommodating cavity; and a counter weight is loaded in the first containing cavity and / or the second containing cavity. According to the embodiment of the invention, the counter weight and the balance correction rotor assembly are loaded in the first containing cavity and / or the second containing cavity, so that the rotor assembly meets the balance requirement, the rotor core does not need to be cut, balance cutting equipment is not needed, the production cost is low, the symmetry of a magnetic circuit of the motor can be ensured, and the electrical performance and the pneumatic performance of the motor are ensured.
Description
technical field [0001] The invention belongs to the field of motors, in particular to a rotor assembly and a switched reluctance motor. Background technique [0002] Switched reluctance motor (Switched Reluctance Motor, SRM) is a type of speed control motor developed after DC motor and brushless DC motor. Research on switched reluctance motors in countries such as Britain and the United States started earlier, and has achieved remarkable results. The power levels of products range from several watts to hundreds of kilowatts, and are widely used in household appliances, aviation, aerospace, electronics, machinery and electric vehicles, etc. field. [0003] The switched reluctance motor has a double salient pole structure, including a stator with windings and a rotor assembly sleeved in the stator. Such as figure 1 As shown, the rotor assembly is composed of a rotor core 11 ′, a rotating shaft and a shading plate 14 ′ arranged on the end face of the rotor core. In this str...
