AI Technical Summary

Benefits of technology

The invention is a fan system that combines a DC brushless motor with a structure that ensures steady operation, powerful driving force, simple structure, and low manufacturing costs. The fan system includes a first mounting bracket at the first air inlet, a second mounting bracket at the second air inlet, a flange plate fixed outside the rotor assembly, and a plurality of mounting legs distributed around the first and second air inlets. These features make the fan system easy to install and convenient for adjusting position.

Problems solved by technology

However, for a high power blower and a heavy wind wheel, a supporting system has a violent vibration and a poor stability.
Although it operates steadily, the system is complicated in structure.
The method has defects of much complicated manufacturing procedure and higher cost.

example 1

[0035]As shown in FIGS. 1-9, a fan system in combination with a DC brushless motor. The fan system comprises: a blower housing 1, a wind wheel 3, a first mounting bracket 4, and a second mounting bracket 5. The blower housing 1 is provided with a cavity 11 inside. A first air inlet 14 is arranged on an upper end surface 12 of the blower housing 1. A second air inlet 15 is arranged on a lower end surface 13 of the blower housing 1. The first air inlet 14 and the second air inlet 15 are communicated with the cavity 11. An air outlet 16 is arranged on the blower housing 1 and communicated with the cavity 11. The DC brushless motor 2 comprises: a shaft 21, a base 22, a stator assembly 23, a rotor assembly 24, a control box 25, and a circuit board 26. The circuit board 26 is arranged in a cavity of the control box 25. The stator assembly 23 is arranged on the base 22. The rotor assembly 24 is arranged on a middle part of the shaft 21. The stator assembly 23 is arranged inside the rotor a...

example 2

[0042]Based on the example 1, the following technical schemes are added: the control box 25 is arranged outside the blower housing 1. The circuit board 26 is arranged inside the control box 25 and is in electric connection with the stator assembly 23 in the first cavity 11 through a wire. The inner side of the second mounting bracket 5 is connected to a bottom of the base 22. The erection loop 52 is attached to the bottom of the base 22 and is fixed on the bottom of the base via a screw.

[0043]The fan system in combination with a DC brushless motor operates in a double-arm support mode. Thus, the fan system is advantageous in a steady operation, powerful driving force, simple structure, simple manufacturing technology, and low manufacturing cost.

Abstract

A fan system in combination with a DC brushless motor. The DC brushless motor includes: a shaft, a base, a stator assembly, a rotor assembly, a control box including a second cavity, and a circuit board. The fan system includes: a blower housing, a wind wheel, a first mounting bracket, and a second mounting bracket. The first mounting bracket is arranged at a first air inlet. The outer side of the first mounting bracket is connected to the upper end surface. The inner side of the first mounting bracket is provided with a first bearing, and the other end of the shaft is disposed on the first bearing. The second mounting bracket is arranged at a second air inlet. The outer side of the second mounting bracket is connected to the lower end surface.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Pursuant to 35 U.S.C. §119 and the Paris Convention Treaty, this application claims the benefit of Chinese Patent Application No. 201220650812.7 filed Nov. 30, 2012, the contents of which are incorporated herein by reference. Inquiries from the public to applicants or assignees concerning this document or the related applications should be directed to: Matthias Scholl P. C., Attn.: Dr. Matthias Scholl Esq., 14781 Memorial Drive, Suite 1319, Houston, Tex. 77079.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a fan system in combination with a DC brushless motor.[0004]2. Description of the Related Art[0005]Two typical methods are employed to assemble a motor and a wind wheel of a fan system. A first method is a single arm installation method, that is, a bracket is arranged on one side to install the motor and the wind wheel. However, for a high power blower and a heavy wind wheel, a supporting system...
