본 발명은 차량용 송풍팬의 송풍모터에 관한 것으로서, 더욱 상세하게는, 차량에 사용되는 송풍팬 또는 냉각팬에 회전력을 제공하는 송풍모터를 센서리스(Sensorless) BLDC 모터로 구성함으로써, 종래의 브러쉬 모터에 비해 소음이 적고, 수명이 길기 때문에 유지보수비용이 절감되도록 하는 차량용 송풍팬의 송풍모터에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower motor for a vehicular blowing fan, and more particularly, to a blower motor for a vehicular blowing fan and a blower motor for providing a rotational force to a cooling fan. The blower motor includes a sensorless BLDC motor. And more particularly to a blowing motor of a blowing fan for a vehicle which is less noise and has a longer lifetime, thereby reducing the maintenance cost.

일반적으로, 자동차 산업은 심각한 오일 가격의 급격한 상승에 따른 에너지 자원의 효율적 사용과 절감, 지구 기후환경의 급격한 변화를 방지하기 위해 자동차의 연료소비로 배출되는 CO2, HC, NOX, CO, PM 등의 공해 저감 대책이 시급하고, 기술적으로 해결해야 하는 현실에 봉착해 있다.In general, the automobile industry has been making efforts to reduce the use and reduction of energy resources in response to drastic increases in oil prices, and to prevent sudden changes in the global climate environment, such as CO 2 , HC, NOx, CO and PM Of pollution reduction measures are in urgent need, and are facing the reality to be solved technically.

이러한 문제점을 해결하기 위한 기술적 과제 중 하나는, 엔진의 연료소비율을 줄여 에너지를 절감하는 것과 유해 배출가스의 배출을 줄여 청정환경을 보전하는 것이다. 즉, 급격히 파괴되고 있는 지구환경을 보전하기 위한 쿄토의정서에서 발표된 보고 자료에 의하면 지구온난화를 유발하는 원인인 CO2의 배출량이 자동차 수송부문에서 26%에 달하여 이에 대한 환경의 심각성이 매우 높다.One of the technical problems to solve these problems is to reduce the fuel consumption rate of the engine to reduce energy and to reduce the emission of harmful exhaust gas to preserve the clean environment. In other words, according to the report published in the Kyoto Protocol for the conservation of rapidly changing global environment, the emission of CO 2 , which is the cause of global warming, reaches 26% in the transport sector and the environment is very serious.

이를 해결하기 위한 방법 중 하나는, 차량용 시스템을 고효율화 하는 것이다. One of the ways to solve this problem is to improve the efficiency of the vehicle system.

통상의 차량용 에어컨 시스템은, 엔진의 동력에 의해 작동되고 냉매를 고온, 고압으로 압축하는 압축기와, 상기 압축기에서 압축된 냉매를 응축시키는 응축기와, 상기 응축기에서 응축된 냉매를 교축시키는 팽창밸브 및 상기 팽창밸브를 통해 팽창된 냉매를 증발시켜 송풍팬을 통해 유입된 공기와 열교환됨에 따라 냉기를 발생시키는 증발기로 이루어진다.A conventional vehicular air conditioning system includes a compressor that is operated by the engine's power and compresses the refrigerant at a high temperature and a high pressure, a condenser that condenses the refrigerant compressed in the compressor, an expansion valve that throttles the refrigerant condensed in the condenser, And an evaporator that evaporates the refrigerant expanded through the expansion valve and generates cool air as heat is exchanged with the air introduced through the blower fan.

또한, 상기 응축기(2)는, 도 1에 도시된 바와 같이, 버스(1)의 지붕 일측에 구비되고, 상기 버스(1)의 배터리에서 전류를 공급받아 회전력을 발생하는 송풍모터(22), 및 상기 송풍모터(22)의 일측에 구비되고 상기 송풍모터(22)의 회전력에 의해 회전하면서 냉매를 응축시키는 송풍팬(24)으로 구성된다.1, the condenser 2 includes a blowing motor 22 provided at one side of a roof of the bus 1 and generating a rotational force by receiving current from the battery of the bus 1, And a blowing fan (24) provided at one side of the blowing motor (22) for condensing the refrigerant while being rotated by the rotational force of the blowing motor (22).

또한, 상기 응축기(2)는, 응축효율을 높이기 위해 통상 4 ~ 8개를 구비한다.The condenser 2 is generally provided with four to eight condensers in order to increase the condensing efficiency.

그러나, 종래의 송풍모터(22)는, 브러쉬 모터를 사용함으로써, 사용년수가 3~4년으로 짧아 자주 교체하여야 하는 문제점이 있다.However, the conventional air blowing motor 22 has a problem that the number of years of use is as short as 3 to 4 years and needs to be frequently changed by using a brush motor.

또한, 상기 송풍모터(22)는, 소음이 크기 때문에 탑승객의 승차감을 저하시키는 문제점이 있다.
Further, the air blowing motor 22 has a problem of reducing the ride quality of a passenger because of a large noise.

본 발명은 상기와 문제점을 해결하기 위해 제안하는 것으로서, 냉매를 응축시키고자 송풍팬에 회전력을 제공하는 송풍모터를 센서리스(Sensorless) BLDC 모터로 구성함으로써, 종래의 브러쉬 모터에 비해 소음이 적고, 수명이 길기 때문에, 유지보수비용이 절감되도록 하는 버스용 에어컨의 응축기를 제공하는 데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a blower motor which is less in noise than a conventional brush motor, And it is an object of the present invention to provide a condenser for a bus air conditioner which can reduce the maintenance cost because the life is long.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 설명하면 다음과 같다(종래와 동일한 구성에 대해서는 동일한 참조부호를 사용하고, 이에 대한 상세한 설명은 생략한다).DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. (The same reference numerals are used for the same components as the conventional ones, and a detailed description thereof will be omitted).

본 발명의 버스용 에어컨의 응축기(2)는 버스(1)에 장착된 배터리에서 제공되는 전류에 위해 회전력을 발생하는 송풍모터(200), 및 상기 송풍모터(200)에 구비되어 상기 송풍모터(200)에서 제공되는 회전력에 의해 회전하면서 냉매를 응축시키는 송풍팬(24)으로 구성된다.The condenser 2 of the bus air conditioner according to the present invention includes a blowing motor 200 for generating a rotational force against a current supplied from a battery mounted on the bus 1 and a blowing motor 200 provided in the blowing motor 200, And a blowing fan (24) for condensing the refrigerant while being rotated by the rotational force provided by the blower (200).

상기 송풍모터(200)는, 도 2에 도시된 바와 같이, 제1커버(210)와, 제2커버(280)가 결합된다.2, the blower motor 200 includes a first cover 210 and a second cover 280 coupled to each other.

또한, 상기 송풍모터(200)는, 도 3에 도시된 바와 같이, 코일(220)과, 상기 코일(220)의 내측에 구비되는 마그넷(230)과, 상기 마그넷(230)의 내측에 구비되는 회전휠(240)과, 상기 회전휠(240)의 내측에 구비되고 상기 회전휠(240)의 회전을 지지하도록 일측에 고정되는 축(250)과, 상기 축(250)의 양단 각각에 구비되고 상기 축(250)의 회전을 지지하도록 상기 제1 및 제2커버(210)(280)에 고정되는 베어링(260)과, 상기 제1 및 제2커버(210)(280)의 어느 일측에 구비되는 회로기판(270), 및 상기 축(250)의 양단 각각에 구비되는 멈춤링(290)이 상기 제1커버(210) 및 제2커버(280)의 내측에 순차적으로 조립된다.3, the air blowing motor 200 includes a coil 220, a magnet 230 disposed inside the coil 220, and a magnet 230 disposed inside the magnet 230 A shaft 250 which is provided on the inner side of the rotation wheel 240 and fixed to one side of the rotation wheel 240 to support the rotation of the rotation wheel 240; A bearing 260 fixed to the first and second covers 210 and 280 to support the rotation of the shaft 250 and a bearing 260 fixed to one side of the first and second covers 210 and 280 And a stop ring 290 provided at both ends of the shaft 250 are sequentially assembled to the inside of the first cover 210 and the second cover 280.

또한, 상기 제1커버(210)의 외측에는 송풍모터(200)를 고정시키기 위한 복수의 플렌지(212)가 구비된다.A plurality of flanges 212 for fixing the blower motor 200 are provided on the outer side of the first cover 210.

또한, 상기 송풍모터(200)는, BLDC 모터(Brushless DC Motor) 구동방식으로 구동됨이 바람직하다.Also, it is preferable that the blowing motor 200 is driven by a BLDC motor (Brushless DC Motor) driving method.

상기 송풍모터(200)는, 도 4에 도시된 바와 같이, PWM제어, 홀센서(Hall Sensor)신호 및 과전류 제어에 의하여 출력제어한다.As shown in FIG. 4, the blower motor 200 performs output control by PWM control, Hall sensor signal, and overcurrent control.

즉, PWM 발진 및 제어는 기본 고정주파수(Clock) 및 PWM발진 회로와 모터속도제어를 하나의 회로로 구성하는 최소의 전기소자로 PWM 제어출력과 스마트제어출력을 통합제어할 수 있도록 하는 것으로 BLDC모터에 구동 전원입력에 대하여 PWM 제어 출력신호와 스마트 제어신호를 입력받아 NAND GATE, AND GATE, EX-OR GATE의 상호 입출력의 ON-OFF 제어에 의하여 6 채널의 출력을 제어하게 되고, 하나의 PWM제어회로를 구성하여 BLDC 모터의 6개 구동장치출력의 동작으로 정의한다.That is, the PWM oscillation and control is a minimum electric device that constitutes the basic fixed frequency (clock) and PWM oscillation circuit and the motor speed control as a single circuit, and can integrally control the PWM control output and the smart control output. The BLDC motor The PWM control output signal and the smart control signal are inputted to the driving power input, and the output of the six channels is controlled by the ON / OFF control of the input / output of the NAND gate, the AND gate and the EX- Circuit is defined as the operation of the six drive outputs of the BLDC motor.

센서리스(Sensorless) BLDC 모터와 일체형으로 되어 있는 구동장치 제어회로와 케이블로 연결이 되어 있어, 케이블의 길이가 커질수록 BLDC 모터의 정전기파와 코일의 유도에 의한 구동 전기 노이즈가 크게 발생되어 BLDC 모터가 동작할 때 에러가 발생할 수 있다.As the length of the cable becomes longer, the electric noise due to the induction of the static wave and the coil of the BLDC motor is largely generated, and the BLDC motor is driven by the control circuit integrated with the sensorless BLDC motor. An error may occur when operating.

상기와 같이 구성된 송풍모터(200)는, 종래의 브러쉬 모터에 비해 소음이 적고, 수명이 길기 때문에, 유지보수비용이 절감된다. 또한, 송풍모터(200)는, 구조가 단순하고, 동력변환 효율이 높으므로, 송풍팬(24)의 구동속도의 정밀제어 및 부하에 따른 가변제어가 가능하다.The blower motor 200 configured as described above has less noise and longer life than conventional brush motors, thus reducing the maintenance cost. Further, since the blowing motor 200 has a simple structure and high power conversion efficiency, it is possible to precisely control the driving speed of the blowing fan 24 and variable control according to the load.

또한, 송풍모터(200)는, 방수형으로 구성됨으로써, 버스(1)의 외부에 설치되어도 누수에 의해 고장을 일으키지 않는다.Further, since the blowing motor 200 is constructed in a waterproof type, even if it is installed outside the bus 1, it does not cause a trouble due to leakage of water.

이상에서 설명한 것은 차량용 송풍팬의 송풍모터를 실시하기 위한 하나의 실시 예에 불과한 것으로서, 본 발명은 상기한 실시 예에 한정되지 아니한다. 본 발명에 속하는 분야에서 통상의 지식을 가진 자라면, 본 발명의 요지를 벗어남이 없이 다양한 변경실시가 가능하다는 것을 이해할 수 있을 것이다.The above description is only one embodiment for implementing a blowing motor of a blowing fan for a vehicle, and the present invention is not limited to the above embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
