specific Embodiment approach 1

[0018] Specific implementation mode one: combine Figure 1 to Figure 8 Describe this embodiment. This embodiment includes a left side arc stator 1, a left support bracket 2, an arc rotor core 3-1, a left permanent magnet 3-2, a right permanent magnet 3-3, and a right support Bracket 4, right side arc-shaped stator 5, fastening screw 6 and base 7; the section of the arc-shaped rotor core 3-1 is T-shaped, and the arc-shaped rotor core 3-1 includes a supporting part 3-1 -1 and effective working part 3-1-2; arc rotor iron core 3-1, left permanent magnet 3-2 and right permanent magnet 3-3 form arc rotor, wherein the left permanent magnet 3-2 The N and S poles are alternately arranged on the left side of the arc-shaped rotor core 3-1, and the N and S poles of the right permanent magnet 3-3 are alternately arranged on the right side of the arc-shaped rotor iron core 3-1; the left side of the arc-shaped stator 1 Located on the left side of the rotor, the right arc-shaped stator 5 is ...

specific Embodiment approach 2

[0019] Specific implementation mode two: combination figure 1 , figure 2 , image 3 , Figure 4 , Image 6 , Figure 7 , Figure 8 with Figure 9 This embodiment is different from Embodiment 1 in that the permanent magnets are arranged as a series magnetic circuit, and the polarities of the permanent magnets are different at the opposite sides of the arc-shaped rotor core. When the N pole on the left side faces the arc-shaped rotor core 3-1, the right side is the S pole facing the arc-shaped rotor core 3-1, and when the left side is the S pole facing the arc-shaped rotor core 3-1, the right side is the N pole facing the arc-shaped rotor core 3-1, and the two sides The N and S poles are arranged alternately.

Embodiment approach 3

[0020] Embodiment 3: The difference from Embodiment 1 or Embodiment 2 is that the arc of the arc-shaped rotor is larger than that of the stator, and the arc length of the arc-shaped rotor can be designed according to the requirements of the operating angle.

Abstract

The invention relates to a double-stator axial magnetic flow arc-shaped permanent magnet motor, and belongs to the technical field of limited angle permanent magnet motors. A rotor is composed of an arc-shaped rotor iron core and permanent magnets, wherein the permanent magnets are installed on the left side and the right side of the arc-shaped rotor iron core. A double-stator assembly is composed of a left-side arc-shaped stator located at the left side of the arc-shaped rotor and a right-side stator located on the right side of the rotor. The left-side arc-shaped stator, the arc-shaped rotor iron core and the permanent magnet on the left side form a left-side axial magnetic flow arc-shaped permanent magnet motor body, the right-side arc-shaped stator, the arc-shaped rotor iron core and the permanent magnet on the right side form a right-side axial magnetic flow arc-shaped permanent magnet motor body, the torque of the two arc-shaped permanent magnet motor bodies is overlaid to serve as the output torque of the whole motor, the power density and the torque density of the motor are improved, the direct drive mode is adopted for a scanning structure, and the problems that the indirect drive mode formed by a high-speed servo motor, a gear set, a gear ring and the like in an existing scanning mechanism causes system vibration, slow motion response, poor dynamic stiffness and the like are solved.

Description

technical field [0001] The invention relates to a double-stator axial flux arc permanent magnet motor, which belongs to the technical field of motors, in particular to a double stator axial flux arc permanent magnet motor which moves within a limited rotation angle. Background technique [0002] The existing scanning servo mechanism mostly adopts the indirect drive mode consisting of "high-speed servo motor + gear set + ring gear". This transmission structure through gear meshing inevitably has nonlinear friction, interval dead zone and elastic deformation. , when completing motions such as starting, accelerating, decelerating, reversing, and braking, it is easy to cause system vibration, slow motion response, and poor dynamic stiffness. These inherent defects make the scanning mechanism further improve its speed regulation performance and positioning capabilities. Difficult to achieve technical breakthroughs. The method of direct drive by arc-shaped torque motor can effect...
