Detailed description of the invention
Easy to understand, according to technical scheme, in the case of the connotation not changing the present invention, one of ordinary skill in the art can imagine the numerous embodiments of the brshless DC motor of band built-in power of the present invention and control function.Therefore, detailed description below and accompanying drawing are only the exemplary illustrations to technical scheme, and are not to be construed as the whole of the present invention or are considered as the restriction to technical solution of the present invention or restriction.
Band built-in power of the present invention and control the brshless DC motor of function, its monnolithic case as it is shown in figure 1, internal structure as shown in Figures 2 and 3, complete machine is divided into two parts: control box 1 and motor 2；Control box 1 and be responsible for the control of motor, and the feedback to operator.
As shown in Figures 2 and 3, motor 2 part includes: rotor 2-1, sealing ring 2-2, drive end bearing bracket 2-3, casing 2-4, stator 2-5, rear end cap 2-6, fan blade case 2-7, fan blade 2-8, end ring 2-9, bearing 2-10, in-built electrical source plate 2-11.
In-built electrical source plate 2-11 provides power supply by battery etc. for motor 2, and it may be mounted on back end cover for motor 2-6.Stator 2-5 and rotor 2-1 is the core of motor rotation, and stator coil produces magnetic field in the case of energising, acts on the rotor of permanent magnet material, and rotor runs through armature spindle 2-1 and passes out.Stator 2-5 is fixed on the inwall of casing 2-4, and rotor 2-1 is fixed on output shaft, and the two ends of output shaft are separately mounted on two bearing 2-10 on drive end bearing bracket 2-3 and rear end cap 2-6, and rotor 2-1 is positioned at the middle, inside of stator 2-5.
It is also equipped with metal-oxide-semiconductor module between in-built electrical source plate 2-11 and rear end cap 2-6, it mainly plays the effect of reversing switch when motor 2 operates, by screw, metal-oxide-semiconductor module is fastened on rear end cap 2-6, scribble thermal grease on contact surface simultaneously, owing to during work, metal-oxide-semiconductor is main heater element, such structure can transfer heat on rear end cap on 2-6 well, thus plays good thermolysis.
Drive end bearing bracket 2-3 and rear end cap 2-6 is arranged on the two ends of casing 2-4, constitutes shell and the support of whole motor.It is respectively arranged with a bearing chamber in the middle of drive end bearing bracket 2-3 and rear end cap 2-6, is used for that bearing 2-10, end ring 2-9 are installed and is arranged in the circlip groove of rear end cap 2-6, in order to limit the axial location of bearing 2-10.
Sealing ring 2-2 is enclosed within the output shaft of rotor 2-1, is positioned at the outside of drive end bearing bracket 2-3, for sealing the bearing chamber of drive end bearing bracket 2-3, has prevented water from entering.
The material of 2-4 casing is aluminum, and there is a lot of radiating ribs on surface, i.e. plays the effect strengthening case strength, can dispel the heat well simultaneously, and the heat that motor 2 operating produces is come out by casing.
Fan blade 2-8 is arranged on the part that rotor of output shaft axle is stretched out from rear end cap 2-6, rotor of output shaft axle can drive the rotation of fan blade 2-8 while rotating, produce centrifugal wind, fan blade case 2-7 is positioned at the outside of fan blade 2-8 and fixing with rear end cap 2-6 is connected, the wind that fan blade 2-8 produces can change the direction of wind when of arriving at fan blade case 2-7, blowing to the position within casing 2-4, the heats in radiating ribs a lot of in casing 2-4 can be carried away by the wind major part, thus reduces the temperature in casing 2-4 further.
Fan blade 2-8 is centrifugal fan, and water splashes can be by fan blade centrifugal force to throwing away on 2-8 fan blade, and fan blade case 2-7 covers on the outside of 2-8 fan blade simultaneously, inherently can withstand being splashed into of water.
As shown in Figure 4, control box 1 and include: transparency cover 1-1, film key plate 1-2, control box cover 1-3, spring pivot pin 1-4, control circuit plate 1-5, upper sealing ring 1-6, control box lower cover 1-7, lower seal 1-8；
Control circuit plate 1-5 is the core controlling box, controls for realizing the operation of motor；It includes all of control circuit, control knob and LCD panel, control knob is used for setting various motor control signal and parameter, LCD panel can show 4 bit digital, the real-time rotating speed of motor can be shown in normal operation process, motor speed and gear are set when, also the button operation of operator can be made display.
Upper sealing ring 1-6 and lower seal 1-8 are elastomeric material；Lower seal 1-8 is arranged between control box lower cover 1-7 and casing 2-4, main responsible whole control box 1 and the sealing of motor 2 coupling part, upper sealing ring 1-6 is mainly responsible for controlling the sealing of box oneself itself, i.e. controls box cover 1-3 and the sealing controlled between box lower cover 1-7.
Controlling box cover 1-3 and control the shell that box lower cover 1-7 is whole control box, being connected by screw, there is sealing ring on 1-6 the position contacted between the two, it is ensured that the sealing that oneself is own, water proof and dust proof.
Film key plate 1-2 is attached to control the surface of box cover 1-3, and it is full back glue type thin film, can play waterproof effect；Simultaneously in the place that LCD panel is corresponding, film key plate is transparent material, can conveniently watch the content that LCD panel shows.And the function instruction of button and position the most all identify 1-2 on film key plate, convenient operation.
Transparency cover 1-1 is arranged on 1-3 on control box cover by spring pivot pin 1-4, uses hinge arrangement, coordinates spring, can automatically close under the action of the spring after uncapping at spring pivot pin 1-4.The material of transparency cover 1-1 itself can prevent sunlight irradiation the most for a long time out of doors from can produce motor control box damage with anti-ultraviolet.
