Brushless motor of range hood

Abstract

The invention relates to a brushless motor of a range hood, belonging to the technical field of range hoods. The brushless motor is characterized in that center holes of a front and rear end covers are respectively and internally provided with a ball bearing; a motor shaft passes through and is connected to the two ball bearings; the front end cover and the rear end cover are respectively arranged at the front end and the rear end of a machine shell; a flange plate is sheathed on and connected to the outer side of the machine shell; wave-shaped mesons are arranged at one sides of the ball bearings; a shaft coupler is arranged in the machine shell and is sheathed on and connected to the motor shaft; magnetic steel is arranged at the outer side of the shaft coupler; a stator core is arranged at the outer side of the magnetic steel; the two ends of the stator core are respectively provided with an insulating paint layer; enamelled wires are arranged at the outer sides of the insulating paint layers and are connected with a three-phase power line; the three-phase power line passes through and is connected to the rear end cover; a wire protecting ring is arranged at the connection part of the three-phase power line and the rear end cover; and a locating pin is arranged at one side of the motor shaft. The brushless motor of the range hood is environment-friendly, low in noise, long in service life, high in reliability, controllable, high in safety and convenient to use.

Description

[0001] Technical field: [0002] The invention relates to the technical field of range hoods, in particular to a brushless motor for range hoods. Background technique: [0003] Now more than 95% of the entire market uses AC series motors to manufacture household range hoods. Because AC motors have obvious shortcomings, such as low efficiency, heavy weight, high heat generation, inconvenient speed regulation, and low safety performance. The biggest shortcoming is that the energy consumption level is too low. Range hoods above 300W are a must for every family. A 300W range hood, even if a family uses it for two hours a day on average (excluding restaurants or industrial ones), is 18 degrees a month, and its energy consumption is high. Invention content: [0004] The object of the present invention is to provide a range hood brushless motor, which is energy-saving, environment-friendly, low-noise, long-life, high-reliability, controllable, high-safety, and easy-to-us...
