Description
제1도는 본 고안장치의 회로도.1 is a circuit diagram of the device.
제2도는 재래식 장치의 회로도이다.2 is a circuit diagram of a conventional device.
본 고안은 자동차 히이터용 모우터의 회전속도를 전자회로를 이용하여 무단(無段)연속으로 조절할 수 있게한 전동기 속도 제어장치에 관한 것이다.The present invention relates to an electric motor speed control device that can adjust the rotational speed of a motor for a car heater in an endless continuous manner using an electronic circuit.
종래 자동차 히이터용 모우터의 회전속도의 조절방식은 도면의 제2도에서와 같이 단식(段式) 스위치로 조작되었기 때문에 전력의 소모가 많았으며, 정해진 속도외에는 임의로 필요한 속도를 가변할수가 없고, 접점의 마모와 소손등으로 고장율이 높으며, 제어에 필요한 부품의 대형화로 취급이 불편하고 장시간의 작동에 따라 과열되어 소손의 우려가 많은 등의 결점이 있었다.In the conventional method of controlling the rotational speed of a motor for a car heater, power is consumed because it is operated by a single switch as shown in FIG. 2, and the required speed can not be arbitrarily changed other than the predetermined speed. The failure rate is high due to contact wear and burnout, and there are many drawbacks such as inconvenient handling due to the enlargement of parts necessary for control and overheating with long operation.
본 고안은 상술한 바와 같은 결점을 완전히 해결하여 전동기의 회전속도를 무단 연속으로 자유로히 가변할수 있도록 전자회로를 이용한 것으로서 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.The present invention is to use the electronic circuit to completely solve the above-mentioned defects and to freely vary the rotational speed of the motor in an endless continuous manner as described in detail according to the accompanying drawings.
트랜지스터(Q1),(Q2)와 콘덴서(C1),(C2)로 구성된 공지한 말티바이브레이터 회로에 있어서, 트랜지스터(Q2)의 콜렉터측의 C 점을 통하여 트랜지스터(Q3),(Q4)를 연결구성하여 C점의 신호에 따라 부하(Load)를 제어함을 특징으로하는 것으로서 도면중 미설명부호 VR은 속도조절용 가변저항 R1,R4는 트랜지스터(Q1),(Q2)의 부하저항, R2,R3은 바이어스 저항을 표시하되 저항(R2)은 가변저항(VR)을 최소값(0)으로 할때 하한점을 정하는 저항으로서 트랜지스터(Q2)의 바이어스 상한설정 및 트랜지스터(Q1)도통 시간의 최소치 설정용 저항이다.In the known malvibrator circuit composed of transistors Q 1 , Q 2 , and capacitors C 1 , C 2 , transistors Q 3 , C through the collector side C of transistor Q 2 , (Q 4 ) is connected to control the load (Load) according to the signal of the point C. In the drawing, reference numeral VR denotes the variable resistor R 1 , R 4 for the speed control transistor (Q 1 ), ( the load resistance of Q 2), R 2, R 3 are, but displayed a bias resistor resistance (R 2) is biased in the resistance as the transistor (Q 2) to set the lower limit points when the variable resistance (VR) to the minimum value (0) It is a resistor for setting the upper limit and setting the minimum value of the transistor Q 1 conduction time.
이와 같이 구성된 본 고안은 전원(＋), (－)에서 공급된 전원은 속도조절용 가변저항기(VR)에 연동된 개폐기 (S)에서 개폐된다. 여기서 개폐기(S)가 폐로를 형성하면 먼저 저항(R5)과 발광다이오드(LED)가 도통되어 표시등이 커짐과 동시에 저항(R1)과 콘덴서(C1) 및 다이오드(D2)를 통하여 트랜지스트(Q2)가 도통되어 트랜지스터 (Q3), (Q4)의 베이스 즉, C점이 b점과 단락상태를 이루어 트랜지스터(Q3),(Q4)가 OFF되어 단자(1),(2)에는 전원(＋), (－)에서 공급된 전원이 차단된다. 이때, 트랜지스터 (Q1)은 OFF상태이므로 콘덴서(C2)에 축적된 전하가 저항(R3)과 트랜지스터(Q2)를 통하여 방전되며, 방전시간은 콘덴서(C2)와 저항(R3)의 시정수에 의해 정해지며 이방전시간이 트랜지스트(Q2)의 도통시간이며 단자(1),(2)에 전원(＋)(－)에서 공급된 전원이 트랜지스터(Q3),(Q4)의 OFF에 의해서 전달되지 않는 시간이다.According to the present invention configured as described above, the power supplied from the power supply (+) and (−) is opened and closed by the switch S linked to the speed control variable resistor VR. In this case, when the switch S forms a closed path, the resistor R 5 and the light emitting diode LED are first turned on to increase the indicator light, and at the same time, through the resistor R 1 , the capacitor C 1 , and the diode D 2 . registry (Q 2) is the conduction transistors (Q 3) (Q 4), a base that is, C point is made a transistor of the point b and the short-circuit state (Q 3) (Q 4) is OFF in the terminal (1), ( 2), the power supplied from the power supply (+) and (-) is cut off. At this time, the transistor (Q 1) is OFF state, so it is the electrical charge stored in the capacitor (C 2) discharge through the resistance (R 3) and a transistor (Q 2), the discharge time of the capacitor (C 2) resistance (R 3 ) is determined by the time constant anisotropic full-time and the conduction time of transfection registry (Q 2), the terminal (1), (2) power supply (+) (in -) of a power transistor (Q 3 supplied by) ( is not transmitted by the OFF time of the Q 4).
콘덴서(C2)의 전하가 0상태가 되면 콘덴서(C2)는 반대방향으로 저항(R4), 다이오드(D1) 및 트랜지스터(Q1)을 통하여 충전되므로 이때 d점의 전위가 트랜지스터(Q1)의 베이스측의 컷트오프(cut off) 전위보다 높게 되어 트랜지스터(Q1)가 순간적으로 도통되고 동시에 트랜지스터(Q1)의 도통으로 인해 e점의 전위가 드랜지스터(Q2)의 베이스측의 컷트오프 전위보다 낮게 되므로 OFF된다.When the charge of the capacitor C 2 is zero, the capacitor C 2 is charged through the resistor R 4 , the diode D 1 , and the transistor Q 1 in the opposite direction. the base-side-cut-off of the Q 1) (cut off) is higher than the potential of the transistor (Q 1) is momentarily being conductive at the same time of the potential at the e point, due to the conduction of the transistor (Q 1) de-transistor (Q 2) The signal is turned off since it is lower than the cutoff potential on the base side.
트랜지스터(Q2)가 OFF되면 C점의 전위가 상승되고 트랜지스터(Q3),(Q4)는 저항(R4)을 통하여 베이스측에 적당한 바이어스가 걸리므로 도통되어 전원(＋),(－)에서 공급된 전원이 단자 (1)(2)에 나타난다.When transistor Q 2 is turned off, the potential at point C is raised, and transistors Q 3 and Q 4 are energized because a proper bias is applied to the base side through resistor R 4 . The power supplied from) appears at terminals (1) and (2).
이번에는 반대로 트랜지스터(Q1)가 도통되면 콘덴서(C1)에 축적된 전하가 저항(R2), 가변저항(VR) 및 트랜지스터(Q1)을 통하여 방전되며,방전시간은 콘덴서 (C1)와 저항(R2)+가변저항(VR)의 시정수에 의해 정해지며 이방전 시간이 트랜지스터 (Q1) 도통시간이며 또는 트랜지스터(Q2)의 OFF시간으로 가변저항(VR)으로서 가변시킬수 있어 단자(1)(2)에 전원 전압이 가해지는 시간을 가변할수 있다.This time, contrary transistor (Q 1) that when conductive capacitor (C 1) the charge is a resistance (R 2), and discharges through a variable resistor (VR) and a transistor (Q 1), the discharge time of the capacitor (C 1 stored in the ) Is determined by the time constant of the resistor (R 2 ) + variable resistor (VR) and the discharge time is the transistor (Q 1 ) conduction time or the transistor (Q 2 ) OFF time can be varied as the variable resistor (VR). The time for which the power supply voltage is applied to the terminals 1 and 2 can be varied.
콘덴서(C1)의 전하가 0상태가 되면 콘덴서(C1)는 반대반향으로 저항(R1), 다이오드(D2) 및 트랜지스터(Q2)를 통하여 충전되므로 e점의 전위가 트랜지스터(Q2)의 베이스측의 컷트오프전위보다 낮게되어 트랜지스터(Q1)가 OFF되어 최초의 상태로되어 이하 똑같은 동작을 되풀이하여 발진한다.When the charge of the capacitor C 1 becomes zero, the capacitor C 1 is charged through the resistor R 1 , the diode D 2 , and the transistor Q 2 in the opposite direction, so that the potential at the point e is the transistor Q. 2 ) is lower than the cut-off potential on the base side of the transistor 2 ), and the transistor Q 1 is turned off to the initial state, and the same operation is repeated in the following.
이와 같은 작용을 반복하여 단자(1)(2)에는 필요로하는 전압이 공급되어 이에 연결된 부하 즉, 전동기(히이터모우터)의 회전속도를 제어할 수 있게 된다.By repeating the above operation, the terminals 1 and 2 are supplied with the required voltage to control the rotation speed of the load, that is, the motor (heater motor) connected thereto.
이 제어 속도는 스위치(S)와 연동된 가변저항기(VR)로서 가변하여 연속 제어된다.This control speed is varied as the variable resistor VR interlocked with the switch S and continuously controlled.
상술한 바와 같이 본 고안은 속도 조절용 가변저항(VR)으로서 트랜지스터(Q3),As described above, the present invention provides a transistor Q 3 as a variable resistor VR for speed regulation,
(Q4)를 스윗칭(Switching)하여 전동기의 회전속도를 연속 가변할 수 있는 것이어서 종래 다단식 스위치의 많은 난문제점을 지양하여 고장없이 간편한 방법으로 절전할 수 있는 이점이 있다.(Q 4 ) by switching (switching) to be able to continuously vary the rotational speed of the motor has the advantage that can save power in a simple way without trouble by avoiding many problems of the conventional multi-stage switch.
