Abstract
Description
Technical Field
[0001] This utility model relates to the field of brushless high-speed motor technology, specifically to a modular brushless high-speed motor. Background Technology
[0002] Brushless high-speed motors mainly consist of a motor body and a driver. They are a typical mechatronic product with speeds reaching over 100,000 rpm. They also use electronic commutation instead of traditional mechanical commutation, avoiding friction and wear between the brushes and the commutator, giving them advantages such as high efficiency, long lifespan, and low noise.
[0003] During use, the motor shaft drives the fan blades to rotate, enabling the fan blades to convert electrical energy into mechanical energy and increase airflow to assist in heat dissipation. However, the airflow is easily affected by the internal structure, reducing the heat dissipation effect. At the same time, the overall assembly is relatively complicated, and there is great inconvenience in maintenance and assembly. Utility Model Content

A first mounting cover is provided on the outer side of the left end of the body and a second mounting cover is provided on the outer side of the right end of the body. A magnet assembly is provided inside the body and a motor shaft located inside the magnet assembly is installed through the inner side of the body.
[0007] The positioning blocks are integrally fixedly installed on the outer sides of the left and right ends of the main body. The first and second mounting covers are both provided with fixing bolts that are connected to the main body.
[0008] The flow guide ring plate is fixedly installed on the inside right end of the machine body by screws, and the inside of the flow guide ring plate is provided with a first prefabricated groove at an equal angle. The left end of the flow guide ring plate is provided with a first bearing located outside the motor shaft.
[0009] Furthermore, the first mounting cover and the second mounting cover are respectively connected to the positioning block by plugging in, and the second mounting cover has a second prefabricated groove through it.
[0010] Furthermore, a second bearing is provided inside both the first mounting cover and the left end of the main body.
[0011] Furthermore, a fan blade located inside the main body is installed on the outer rear end of the motor shaft, and the fan blade is located directly to the right of the guide ring plate.
[0012] Furthermore, the middle part of the flow guide ring plate is inclined to the left, and a protruding structure is provided on the outer side of the left end of the flow guide ring plate.
[0013] Furthermore, the right end of the motor shaft extends to the inner side of the middle of the second mounting cover.
[0014] This utility model has the following advantages:
[0015] 1. The first and second mounting covers are respectively installed on the outer sides of the left and right ends of the main body and fixed by fixing bolts. The right end of the main body is open. During maintenance and assembly, the internal units of the main body can be installed first, and then the first and second mounting covers can be assembled on the outer side of the main body in sequence.
[0016] 2. Through the guide ring plate and the first prefabricated groove, the guide ring plate can effectively guide the airflow increased by the fan blades, making it easier for the airflow to pass through the first prefabricated groove to effectively dissipate heat from the inside of the machine body, thus avoiding excessive internal temperature.
[0017] 3. The first and second bearings are located on the outer sides of the left and right ends of the motor shaft, respectively, to ensure smooth operation of the motor shaft and reduce shaking. Attached Figure Description
