Abstract
The utility model provides a technical scheme of a brushless direct-current electromotor control device for a bladeless fan. According to the scheme, the control device comprises a driving circuit module for driving a brushless direct-current electromotor, wherein the driving circuit module is connected with a normal-reverse rotation control module; the normal-reverse rotation control module is connected with a central processing module; the central processing module is connected with a rotating speed control module; the rotating speed control module is connected with the driving circuit module; the driving circuit module is also connected with a display module; and a rotating speed feedback module is connected with the central processing module. By the control device, the brushless direct-current electromotor can be accurately controlled, good operation is ensured, and energy consumption and noise are reduced.
Description
Technical field
The utility model relates to a kind of X in brushless DC motor control device that is used to not have the flabellum fan.
Background technology
In the prior art; Be applicable to that the motor in the fan that does not have electric fan much is brshless DC motor; But because control mode is unreasonable, can form the rotary air noise, form bigger set noise or machine vibration; And expend very big electric energy, this is the existing in prior technology weak point.
Summary of the invention
The purpose of the utility model; Be exactly not enough to existing in prior technology; And a kind of technical scheme that is used to not have the X in brushless DC motor control device of flabellum fan is provided; The control device of this scheme can accurately be controlled brushless DC motor, guarantees good operation, has reduced energy consumption and noise.
This programme is realized through following technical measures: a kind of X in brushless DC motor control device that is used to not have the flabellum fan; Include the drive circuit module that drives brushless DC motor; The characteristics of this programme are: described drive circuit module is connected with a rotating control module, and described positive and negative dress control module is connected with a central processing module, and described central processing module is connected with a rotational speed control module; Described rotational speed control module is connected with drive circuit module; Described drive circuit module also is connected with a display module, in addition, also has a speed feedback module to be connected with described central processing module.
The beneficial effect of this programme can be learnt according to the narration to such scheme, obtains rotary speed information owing in this scheme, there is the speed feedback module to be beneficial to central processing module, is convenient to control, and the speed feedback module is a position transducer; There is a rotating control module to be connected, can realizes rotating and reverse of brushless DC motor with central processing module; Also have a rotational speed control module, can control the rotating speed of brushless DC motor through drive circuit module.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
