Description
Technical field
The present invention relates to a kind of drive unit, relate in particular to a kind of drive unit of DC Brushless Motor.
Background technology
The most general power resources of industrial quarters can be divided into alternating current motor and d.c. motor at present.D.c. motor is divided into direct-current brush motor and DC Brushless Motor (Brushless DC Motor is abbreviated as BLDC) again.Because the progress of material science, research and development have more been promoted in recent years to DC Brushless Motor (BLDC).DC Brushless Motor (BLDC) has peace and quiet, noiselessness, face maintenance, long characteristic of life-span, and especially high efficiency output has more caused the attention of global industrial circle to the outstanding representation of energy-conservation and environmental protection.
But in the prior art, brushless frequency converter does not directly apply on the DC Brushless Motor in DC Brushless Motor.
In view of this, how designing a kind of drive unit, along with variation of temperature is come the rotating speed of timely adjustment motor fan, thereby reach the purpose of energy savings, is the problem that the insider needs solution badly.
Summary of the invention
In prior art, the rotating speed of motor fan can not come this defective of timely adjustment along with variation of temperature in the drive unit, the invention provides a kind of drive unit.
According to the present invention, a kind of drive unit is provided, wherein, comprising:
DC Brushless Motor;
Control cabinet is fixed in the rear end of said DC Brushless Motor;
Control board is positioned at said control cabinet, and said control board has temperature sensor; And
Brushless frequency converter is arranged on the said control board and is electrically connected at said DC Brushless Motor, to regulate the voltage of said DC Brushless Motor.
Preferably, said control cabinet is fixed in the rear end of said DC Brushless Motor through screw.
Preferably, more comprise support.
Preferably, said DC Brushless Motor is fixed on the said support.
Preferably, said DC Brushless Motor is fixed on the said support through screw.
Preferably, said brushless frequency converter is adjusted to 220V with the voltage of said DC Brushless Motor from 380V.
Advantage of the present invention is: brushless frequency converter is applied to DC Brushless Motor; And respond to the variation of ambient temperature through a temperature sensor; Thereby send signal so that brushless frequency converter is regulated the voltage of DC Brushless Motor to brushless frequency converter; Control the rotation speed of the fan of DC Brushless Motor at last, reach the purpose of energy savings, can improve protection simultaneously environment.
Description of drawings
The reader with reference to advantages after the embodiment of the present invention, will become apparent various aspects of the present invention.Wherein,
Fig. 1 shows the structured flowchart according to drive unit of the present invention.
Fig. 2 shows the STRUCTURE DECOMPOSITION figure according to drive unit of the present invention.
Embodiment:
With reference to the accompanying drawings, specific embodiments of the invention is done further to describe in detail.
Fig. 1 shows the structured flowchart according to drive unit of the present invention.Fig. 2 shows the STRUCTURE DECOMPOSITION figure according to drive unit of the present invention.In conjunction with reference to Fig. 1 and Fig. 2, drive unit 1 comprises DC Brushless Motor 10, control cabinet 11, control board 12 and brushless frequency converter 13.Wherein, control cabinet 11 is fixed in the rear end of DC Brushless Motor 10, and DC Brushless Motor 10 is provided with axle 101 corresponding to the other end of rear end.In the present embodiment, control cabinet 11 is fixed on the DC Brushless Motor 10 through screw.Control board 12 is positioned at control cabinet 11, and control board 12 is provided with temperature sensor (not illustrating), is used for responding to the temperature of external environment.Brushless frequency converter 13 also is arranged on the control board 12, and electrically connects with DC Brushless Motor 10.In the present embodiment, DC Brushless Motor 10 is fixed on the support 14, and can be fixing through screw 15.Temperature sensor can the sensing external environment temperature, when ambient temperature was low, temperature sensor can induce and send signal to brushless frequency converter 13; The voltage that brushless then frequency converter 13 is regulated DC Brushless Motor 10 makes its reduction, for example, reduces to 220 from 380V; Correspondingly; The rotating speed of the fan of DC Brushless Motor 10 can reduce, therefore, and can energy savings.
Advantage of the present invention is: brushless frequency converter is applied to DC Brushless Motor; And respond to the variation of ambient temperature through a temperature sensor; Thereby send signal so that brushless frequency converter is regulated the voltage of DC Brushless Motor to brushless frequency converter; Control the rotation speed of the fan of DC Brushless Motor at last, reach the purpose of energy savings, can improve protection simultaneously environment.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
