The utility model is in characterized in that the brushless DC motor is used to drive the evaporating fan; as no physical brush is provided for the brushless DC motor, mechanical contact and wear is avoided between a rotor and a stator, thereby the motor has a long service life, high efficiency and free from maintenance; the system has a linear speed control function without an external regulating circuit.
Description
(1) technical field
The utility model relates to a kind of air conditioning for automobiles evaporation fan.
(2) background technology
Existing air conditioning for automobiles evaporation fan adopts permanent magnet DC motor driving impeller of blower to come Cooling Air-conditioning System.Permanent magnet DC motor adds that direct voltage just starts working, and whole system is simple in structure, and compactness has obtained using widely in air conditioning for automobiles.But permanent magnet DC motor all has carbon brush and commutator.Brush and commutator have CONTACT WITH FRICTION, so such permanent magnet DC motor needs often to safeguard, even need change brush over time; Brush is easy to cause the motor short trouble can staying on the commutator by some conductive powders of generation after the wearing and tearing simultaneously.Thereby the life-span of this class air conditioning for automobiles evaporation fan is shorter.
(3) summary of the invention
In order to overcome the short deficiency in useful life of air conditioning for automobiles evaporation fan in the prior art, the utility model provides a kind of long service life, non-maintaining air conditioning for automobiles evaporation fan.
The technical scheme in the invention for solving the technical problem is: a kind of air conditioning for automobiles evaporation fan, comprise the blower fan body, described blower fan body comprises shell, fan blade and rotating shaft are arranged in the described shell, described fan blade is fixed in the described rotating shaft, it is characterized in that: also comprise brshless DC motor, the output shaft of described brshless DC motor and described rotating shaft are affixed.
Further, described brshless DC motor comprises motor body and driver, described motor body comprises shell and is positioned at stator, rotor, the output shaft of described shell, described driver comprises control circuit, drive circuit and the three-phase brachium pontis master power circuit that connects successively, and described three-phase brachium pontis master power circuit is electrically connected with described motor body; Also be provided with the position transducer that is used for the detection rotor position in the described motor body, described position transducer is connected with described control circuit.At this moment, by the position of position transducer detection rotor, and provide the position signalling of rotor polarity.
Further, described brshless DC motor comprises motor body, is used for the position detecting circuit of detection rotor position, driver, described motor body comprises shell and is positioned at stator, rotor, the output shaft of described shell, described driver comprises control circuit, drive circuit and the three-phase brachium pontis master power circuit that connects successively, described three-phase brachium pontis master power circuit is electrically connected with described motor body, and described position detecting circuit is connected with described control circuit.At this moment,, and provide the position signalling of rotor polarity, and omitted the position transducer of common brshless DC motor by the position of position detecting circuit detection rotor.
The utility model drives impeller of blower by brshless DC motor and comes Cooling Air-conditioning System in use.
The beneficial effects of the utility model are: 1. adopt brshless DC motor to drive, brshless DC motor does not have brush, thereby does not have Mechanical Contact between stator and the rotor, do not have wearing and tearing, thereby motor does not need to safeguard that electrical machinery life is long.2. electric efficiency height.3. system has the linear speed regulation function, and need not outside regulating circuit.4. when adopting position detecting circuit detection rotor position, omitted the position transducer of common brshless DC motor, compact conformation, it is low to reduce cost.
