Description

Technical Field

[0001] This utility model relates to the field of rotor support technology, specifically a rotor support for a vehicle permanent magnet synchronous motor. Background Technology

[0002] Automotive permanent magnet synchronous motors mainly consist of a stator, rotor, and end covers. The stator windings surround the stator permanent magnets, and the rotational frequency and speed of the magnetic field are adjusted by controlling the input current frequency. The rotor contains embedded permanent magnets. When the motor is stationary, three-phase alternating current is applied to the stator windings, generating a rotating stator magnetic field. When the rotor's rotating magnetic field approaches synchronization, the rotor windings no longer generate induced current; instead, torque is generated by the interaction between the permanent magnets and the stator magnetic field, driving the rotor to rotate and achieving the conversion of electrical energy into mechanical energy. The rotor support is used for assembling the rotor components.

[0003] However, the number of permanent magnets and partitions inside the existing rotor support is relatively fixed, making it inconvenient to adjust the installation of the permanent magnets according to the needs. Utility Model Content

[0004] The purpose of this invention is to provide a rotor bracket for a vehicle permanent magnet synchronous motor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotor bracket for a vehicle permanent magnet synchronous motor, comprising a bracket rod and an adjustment assembly. A front baffle is provided on the left side of the bracket rod. The adjustment assembly for adjusting the number of permanent magnets in the rotor is located on the right side of the front baffle. The adjustment assembly includes an inner plate, a mounting groove, an assembly rod, a fixing bracket, and an outer hoop. The inner plate has a mounting groove on its side, and an assembly rod is provided inside the mounting groove. A fixing bracket is installed on the side of the end of the assembly rod, and an outer hoop is installed on the outside of the inner plate.

[0006] Furthermore, twelve mounting slots are arranged in a ring around the center point of the inner panel, and the number of mounting slots is the same as the number of assembly rods.

[0007] Furthermore, a connecting ring is provided on the left side of the front baffle, and a bearing is connected to the left side of the connecting ring.

[0008] Furthermore, a fixing plate with annular shape is installed on the right side of the support rod.

[0009] Furthermore, a rear baffle is connected to the right side of the fixed perforated plate, and a limiting component for adjusting the spacing limit is provided on the right side of the rear baffle.

[0010] Furthermore, the limiting component includes a limiting ring and a fixing groove, and the fixing groove is formed on the surface of the limiting ring.

[0011] Furthermore, the limiting component also includes a limiting hole and an outer ring, the limiting hole is provided in the middle of the fixing groove, and the outer ring is installed inside the fixing groove.

[0012] Furthermore, a bearing is connected to the right side of the limiting ring, and an assembly slot is provided on the surface of the end of the support rod.

[0013] This utility model provides a rotor bracket for a vehicle permanent magnet synchronous motor, which has the following advantages:

[0014] 1. This utility model uses an installation slot for the snap-fit ​​installation of partitions. As needed, the assembly rod and the fixing bracket can be removed from the installation slot, and the corresponding partition can be installed according to the reserved installation slot, thereby installing different numbers of permanent magnets. The fixing bracket is used to fix the assembly rod in the installation slot, and the outer hoop ring is used to externally wrap and limit the remaining assembly rod after the partition is installed.

[0015] 2. This utility model uses a fixed hole plate and an inner plate to install permanent magnet blocks. The limiting ring allows the rear baffle and the fixed hole plate to move outside the support rod. The distance between the fixed hole plate and the inner plate can be adjusted so that permanent magnet blocks of different lengths can be installed inside. The fixing groove fixes the limiting ring to the outside of the support rod through the internal limiting hole. Attached Figure Description

The adjustment assembly 3 includes an inner plate 301, a mounting groove 302, an assembly rod 303, a fixing bracket 304, and an outer hoop 305. The inner plate 301 has a mounting groove 302 on its side, which is used for the engagement and installation of partitions. The assembly rod 303 and the fixing bracket 304 can be removed from the mounting groove 302 as needed, and corresponding partitions can be installed according to the reserved mounting groove 302, thereby installing different numbers of permanent magnets. The mounting groove 302 is provided with an assembly rod 305 inside. 03. A fixing bracket 304 is installed on the side of the end of the assembly rod 303. The fixing bracket 304 is used to fix the assembly rod 303 in the mounting groove 302. An outer hoop ring 305 is installed on the outside of the inner plate 301. The outer hoop ring 305 is used to externally wrap and limit the remaining assembly rod 303 after the partition is installed. There are twelve mounting grooves 302 arranged in a ring around the center point of the inner plate 301. The number of mounting grooves 302 and the number of assembly rods 303 are the same. A connecting ring 4 is provided on the left side of the front baffle 2. A bearing 5 is connected to the left side of the connecting ring 4. A fixing hole plate 6 is installed on the right side of the outside of the support rod 1. The fixing hole plate 6 is circular in shape. The fixing hole plate 6 cooperates with the inner plate 301 to install the permanent magnet block.

[0022] like Figure 3 As shown, a rear baffle 7 is connected to the right side of the fixed hole plate 6, and a limiting component 8 for adjusting the spacing limit is provided on the right side of the rear baffle 7. The limiting component 8 includes a limiting ring 801 and a fixing groove 802. The fixing groove 802 is opened on the surface of the limiting ring 801. The limiting ring 801 allows the rear baffle 7 and the fixed hole plate 6 to move outside the support rod 1, adjusting the spacing between the fixed hole plate 6 and the inner plate 301 so that permanent magnet blocks of different lengths can be installed inside. The limiting component 8 also includes a limiting hole 803 and an outer ring 804. A limiting hole 803 is opened in the middle of the fixing groove 802.

A bearing 9 is connected to the right side of the limiting ring 801. An assembly slot 10 is opened on the surface of the end of the support rod 1.

[0023] In summary, the rotor support of the permanent magnet synchronous motor used in this vehicle is first based on... Figures 1-3As shown in the structure, when the permanent magnet block and partition are installed inside the inner panel 301 and the fixing hole plate 6, the assembly rod 303 and the fixing bracket 304 can be removed from the mounting groove 302 as needed. The corresponding partition is installed according to the reserved mounting groove 302, so that different numbers of permanent magnets can be installed in the inner panel 301 and the fixing hole plate 6. The assembly rod 303 that is not removed is fixedly installed in the mounting groove 302 by the fixing bracket 304, and the outer hoop ring 305 is used to externally wrap and limit the remaining assembly rod 303 after the partition is installed, thereby increasing the installation firmness. According to the length of the permanent magnet block and the partition, the limiting ring 801 can be moved outside the support rod 1 to adjust the distance between the fixing hole plate 6 and the inner panel 301. After adjustment, the fixing groove 802 fixes the limiting ring 801 to the outside of the support rod 1 through the internal limiting hole 803.
