Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] see Figure 1-2 , a brushless motor for an electric wheelchair, comprising a motor 1, both sides of the bottom of the motor 1 are fixedly connected with a shock-absorbing column 5, by setting the shock-absorbing column 5, the motor 1 can be damped, and the motor 1 can be avoided. The vibration generated by the motor 1 during operation causes the motor 1 to shake, which increases the stability of the motor 1 and makes the stabilization effect of the moto...

Abstract

The invention discloses a brushless electric motor for an electric wheelchair, comprising a motor, wherein the top and the bottom of the right side of the motor cavity are fixedly connected with two fixing frames, the opposite side of the two fixing frames is movably connected with a rotating shaft, the two sides of the rotating shaft are fixedly connected with fan blades, and a bearing seat is fixedly connected with the center of the right side of the motor cavity. In accordance with that present invention, the motor, housing, air inlet duct, spindle, fixed bracket, rotating shaft, second airoutlet duct, suction fan, support plate, First air outlet duct, the third air outlet pipe and the bearing seat are used together, and solves the problem of poor heat dissipation effect of brushless motor for electric wheelchair, The electric wheelchair brushless motor has the advantages of good heat dissipation effect, slowing down the aging condition of parts in the brushless motor, prolonging the service life of the brushless motor, bringing great convenience to the user, and improving the practicability of the brushless motor for the electric wheelchair.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a brushless motor for electric wheelchairs. Background technique [0002] The brushless DC motor is composed of the main body of the motor and the driver. It is a typical mechatronics product. Since the brushless DC motor operates in a self-controlled manner, it will not be in the rotor like a synchronous motor that is started under heavy load under variable frequency speed regulation. Adding an additional start winding on it will not cause oscillation and out of step when the load changes suddenly, and the permanent magnet of the brushless DC motor with small and medium capacity. [0003] The brushless motor is one of the important components of the electric wheelchair. When the brushless motor drives the electric wheelchair to move, a lot of heat will be generated after a long time of work. Running will cause the components in the brushless motor to age, thereby shortening the ...
