Description
본 발명은 스위치드 릴럭턴스 모터(Switched Reluctance Motor; 이하, SRM이라 한다)의 고정자 권선방식에 관한 것으로, 특히 U상, V상, W상을 연결하는 권선방식으로 에너지 이용률 증가 및 소음 감소 효과를 높이는 스위치드 릴럭턴스 모터의 고정자 권선방식에 관한 것이다.The present invention relates to a stator winding method of a switched reluctance motor (hereinafter referred to as SRM), in particular, a winding method connecting U, V, and W phases to increase energy utilization and reduce noise. A stator winding method of a switched reluctance motor.
일반적으로, SRM은 1여자 방식으로 1상씩 순차적으로 여자되어 자력을 발생하도록 3상(U상, V상, W상)의 권선이 감겨진 고정자와, 상기 고정자에서 발생한 자력에 의해 구동력을 받아 회전하는 회전자로 구성되어 있다.In general, the SRM is a stator in which windings of three phases (U phase, V phase, and W phase) are wound so as to be sequentially excited one by one in a single excitation manner, and rotated by a driving force by the magnetic force generated in the stator. It is composed of a rotor.
상기와 같이 구성된 SRM의 종래 고정자 권선방식은 도 1에 도시한 바와같이, U상의 권선(w1,w2), V상의 권선(w3,w4), W상의 권선(w5,w6)이 각각 분리되어 있고, 위치센서에 의해 트랜지스터(TR1,TR2)에 스위칭신호가 인가되어 트랜지스터(TR1,TR2)가 턴온되면 도 1의 ①과 같이 폐회로가 형성되어 U상의 권선(w1,w2)에 전류가 흐르고 이 전류에 의해 기자력이 발생하여 회전자를 구동시킨다.In the conventional stator winding method of the SRM configured as described above, as shown in FIG. 1, the U phase windings w1 and w2, the V phase windings w3 and w4, and the W phase windings w5 and w6 are separated from each other. When a switching signal is applied to the transistors TR1 and TR2 by the position sensor and the transistors TR1 and TR2 are turned on, a closed circuit is formed as shown in ① of FIG. 1 to flow a current through the U phase windings w1 and w2. Magnetic force is generated by the rotor to drive the rotor.
상기 회전자 구동에 의해 위치센서의 신호가 바뀌어 트랜지스터(TR3,TR4)가 턴온되면(이때, TR1,TR2는 턴오프됨) 도 1의 ②와 같이 폐회로가 형성되어 V상의 권선(w3,w4)에 전류가 흐르고 이 전류에 의해 기자력이 발생하여 회전자가 구동하는데, 상기의 동작을 반복적으로 수행하여 회전자의 구동력이 발생한다.When the signal of the position sensor is changed by the rotor driving and the transistors TR3 and TR4 are turned on (at this time, TR1 and TR2 are turned off), a closed circuit is formed as shown in ② of FIG. An electric current flows in and a rotor force is generated by this current, and the rotor is driven, and the driving force of the rotor is generated by repeatedly performing the above operation.
한편, 상기 동작에서 트랜지스터(TR3,TR4)가 턴온(TR1,TR2는 턴오프)되는 순간, U상의 권선(w1,w2)에 축적된 에너지가 도 1의 ③과 같이 다이오드(D1,D2)를 통해 콘덴서(C)로 충전되는 자유회전(freewheel) 현상이 발생한다.On the other hand, in the above operation, when the transistors TR3 and TR4 are turned on (TR1 and TR2 are turned off), the energy accumulated in the windings w1 and w2 of the U phase is connected to the diodes D1 and D2 as shown in FIG. A freewheel phenomenon, which is charged by the condenser C, occurs.
그런데, 종래 SRM의 고정자 권선방식에 있어서는, 고정자의 3상(U상, V상, W상)이 분리되어 있어 1상이 여자되고 다음 상이 여자되는 순간 여자되었던 상에 축적된 에너지를 다음 상에 분배하지 못하므로 에너지 이용률이 낮고, 토크 리플에 인한 소음발생이 심하다는 문제점이 있었다.However, in the stator winding method of the conventional SRM, the three phases (U phase, V phase, W phase) of the stator are separated so that the energy stored in the phase that was excited at the moment when one phase is excited and the next phase is excited is distributed to the next phase. Since it does not have a low energy utilization rate, there was a problem that the noise generated by the torque ripple is severe.
따라서, 본 발명은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로, 고정자의 3상(U상, V상, W상)을 연결하는 권선방식으로 1상이 여자되고 다음 상이 여자되는 순간 여자되었던 상의 권선에 축적된 에너지를 다음 상으로 분배하여 에너지 이용률 증가 및 토크 리플감소로 소음을 줄일 수 있는 스위치드 릴럭턴스 모터의 고정자 권선방식을 제공하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, the phase that was excited at the moment when one phase is excited and the next phase is excited by the winding method of connecting three phases (U phase, V phase, W phase) of the stator. It is an object of the present invention to provide a stator winding method of a switched reluctance motor that can reduce noise by increasing energy utilization and reducing torque ripple by distributing the energy stored in the winding to the next phase.
상기 목적을 달성하기 위하여 본 발명에 의한 스위치드 릴럭턴스 모터의 고정자 권선방식은, 1여자 방식으로 3상(U상, V상, W상)을 순차적으로 여자시켜 자력을 발생하는 SRM의 고정자에 있어서, 1상이 여자되고 다음 상이 여자되는 순간 여자되었던 상의 권선에 축적된 에너지를 다음에 여자될 나머지 상의 권선에 분배하도록 상기 U상, V상, W상을 연결하는 것을 특징으로 한다.In order to achieve the above object, the stator winding method of a switched reluctance motor according to the present invention is a stator of an SRM that generates magnetic force by sequentially exciting three phases (U phase, V phase, W phase) in a single excitation method. And connect the U phase, V phase, and W phase to distribute the energy accumulated in the winding of the phase that was excited when one phase is excited and the next phase is excited to the winding of the remaining phase to be excited next.

도 2에 도시한 바와같이, 정류수단(100)은 전원입력단(1)으로부터 입력되는 AC입력전원을 정류 및 평활시켜 DC전원으로 변환하는 A/D컨버터로서, 이 정류수단(100)은 상기 전원입력단(1)으로부터 입력되는 AC입력전원을 소정의 직류전원으로 전파정류하는 브리지정류기(102)와, 상기 브리지정류기(102)에 의해 전파정류된 직류전원에 포함되어 있는 리플성분을 필터링함과 동시에 그 전파정류된 직류전압을 충전하도록 상기 브리지정류기(102)의 출력단에 접속된 콘덴서(C1)로 구성되어 있다.As shown in FIG. 2, the rectifying means 100 is an A / D converter that rectifies and smoothes AC input power input from the power input terminal 1 and converts the same into a DC power source. The bridge rectifier 102 for full-wave rectifying the AC input power input from the input terminal 1 to a predetermined direct current power source, and the ripple component contained in the direct-current power supply rectified by the bridge rectifier 102 are filtered. The capacitor C1 is connected to the output terminal of the bridge rectifier 102 so as to charge the full-wave rectified DC voltage.
그리고, 전원수단(110)은 상기 정류수단(100)에서 변환된 DC전원을 입력받아 소정의 직류전압(DC 5V의 마이컴 구동전원)으로 변환하여 출력하는 정전압 레귤레이터(Voltage Regulator)이고, 제어수단(120)은 상기 전원수단(110)으로부터 출력되는 직류전압을 인가받아 고정자(150)의 3상(U상, V상, W상)을 순차적으로 여자하기 위한 스위칭신호를 출력하는 마이컴이다.In addition, the power supply unit 110 is a constant voltage regulator (Voltage Regulator) for receiving the DC power converted by the rectifying means 100 is converted to a predetermined DC voltage (DC 5V microcomputer drive power supply) and output, 120 is a microcomputer that receives a DC voltage output from the power supply unit 110 and outputs a switching signal for sequentially exciting three phases (U phase, V phase, W phase) of the stator 150.
또한, 고정자구동수단(130)은 상기 제어수단(120)으로부터 출력되는 스위칭신호를 입력받아 고정자(150)의 순차구동을 제어하는 것으로서, 이 고정자구동수단(130)은 상기 제어수단(120)의 출력단자(P1,P2)로부터 출력되는 제어신호를 입력받아 U상의 권선(w1,w2)에 전류가 흐르도록 턴온/턴오프 동작하는 트랜지스터(TR1,TR2)와, 상기 제어수단(120)의 출력단자(P3,P4)로부터 출력되는 제어신호를 입력받아 V상의 권선(w3,w4)에 전류가 흐르도록 턴온/턴오프 동작하는 트랜지스터(TR3,TR4)와, 상기 제어수단(120)의 출력단자(P5,P6)로부터 출력되는 제어신호를 입력받아 W상의 권선(w5,w6)에 전류가 흐르도록 턴온/턴오프 동작하는 트랜지스터(TR5,TR6)와, 상기 트랜지스터(TR1~TR6)의 턴오프동작시 상기 고정자(150)의 3상(U상, V상, W상)에 발생하는 역기전력을 바이패스하여 상기 트랜지스터(TR1~TR6)를 보호하는 플라이휠 다이오드(D1~D6)로 구성되어 있다.In addition, the stator driving means 130 receives the switching signal output from the control means 120 to control the sequential driving of the stator 150, the stator driving means 130 of the control means 120 Transistors TR1 and TR2 which are turned on / off to receive a control signal output from the output terminals P1 and P2 so that current flows in the windings w1 and w2 of the U phase, and the output of the control means 120. Transistors TR3 and TR4 which turn on / turn off to receive a control signal output from the terminals P3 and P4 so that current flows in the windings w3 and w4 of the V phase, and an output terminal of the control means 120. Transistors TR5 and TR6 which turn on / turn off to receive a control signal outputted from P5 and P6 so that current flows in the windings w5 and w6 of the W phase, and turn-off of the transistors TR1 to TR6. In operation, the transformer bypasses back electromotive force generated in three phases (U phase, V phase, and W phase) of the stator 150. Stirrer consists of a flywheel diode (D1 ~ D6) to protect (TR1 ~ TR6).
또, 위치감지수단(140)은 상기 고정자(150)의 3상(U상, V상, W상) 순차구동시 회전자(도시안됨)가 구속되지 않도록 회전자 위치를 감지하여 상기 제어수단(120)에 출력하는 위치센서이고, 상기 고정자(150)는 3상(U상, V상, W상)의 중성점이 연결되어 있다.In addition, the position detecting means 140 detects the position of the rotor so that the rotor (not shown) is not constrained when the three-phase (U-phase, V-phase, W-phase) of the stator 150 is sequentially driven. Position sensor outputs to 120, the stator 150 is connected to the neutral point of the three phase (U phase, V phase, W phase).
이하, 상기와 같이 구성된 스위치드 릴럭턴스 모터의 고정자 권선방식의 작용효과를 설명한다.Hereinafter, the effect of the stator winding method of the switched reluctance motor configured as described above will be described.
전원입력단(1)으로부터 AC입력전원이 인가되면, AC입력전원은 정류수단(100)의 브리지정류기(102)를 통해 소정의 직류전압으로 정류되고, 브리지정류기(102)에 의해 정류된 직류전압에 포함된 리플성분은 콘덴서(C1)를 통해 필터링된다.When AC input power is applied from the power input terminal 1, the AC input power is rectified to a predetermined DC voltage through the bridge rectifier 102 of the rectifying means 100, and is applied to the DC voltage rectified by the bridge rectifier 102. The included ripple component is filtered through the condenser C1.
상기 콘덴서(C1)에 의해 필터링된 직류전압은 전원수단(110)을 통해 일정레벨의 정전압(Vcc;5V)으로 변환되어 5V의 제어수단(120) 구동전압이 출력된다.The DC voltage filtered by the capacitor C1 is converted into a constant voltage (Vcc; 5V) of a predetermined level through the power supply unit 110, and a driving voltage of 5V control means 120 is output.
따라서, 상기 제어수단(120)에서는 전원수단(110)으로부터 출력되는 5V의 구동전압을 인가받아 사용자가 원하는 속도로 SRM의 속도를 조절하도록 동작을 시작한다.Therefore, the control means 120 receives the driving voltage of 5V output from the power supply means 110 and starts the operation to adjust the speed of the SRM at a desired speed.
먼저, 제어수단(120)은 SRM의 회전자 위치를 파악하여 구동시켜야 할 트랜지스터(TR1~TR6)를 선택해야 하므로, 위치감지수단(140)으로부터 입력단자(I1~I3)를 통해 입력되는 신호를 체크하여 고정자(150)의 3상(U상, V상, W상)을 순차적으로 여자하기 위한 스위칭신호를 출력단자(P1~P6)를 통해 출력한다.First, since the control means 120 should select the transistors TR1 to TR6 to be driven by grasping the rotor position of the SRM, the control means 120 receives a signal input from the position sensing means 140 through the input terminals I1 to I3. By checking, a switching signal for sequentially exciting three phases (U phase, V phase, W phase) of the stator 150 is output through the output terminals P1 to P6.
상기 위치감지수단(140)에 의해 제어수단(120)의 출력단자(P1,P2)로부터 스위칭신호가 인가되어 트랜지스터(TR1,TR2)가 턴온되면 도 3의 ①과 같이 폐회로가 형성되어 U상의 권선(w1,w2)에 전류가 흐르고 이 전류에 의해 기자력이 발생하여 회전자를 구동시킨다.When the switching signals are applied from the output terminals P1 and P2 of the control means 120 by the position sensing means 140 and the transistors TR1 and TR2 are turned on, a closed circuit is formed as shown in ① of FIG. An electric current flows in (w1, w2), and magnetism is generated by this current to drive the rotor.
상기 회전자 구동에 의해 위치감지수단(140)의 신호가 바뀌면, 제어수단(120)의 출력단자(P3,P4)로부터 스위칭신호가 인가되어 트랜지스터(TR1,TR2)는 턴오프되고, 트랜지스터(TR3,TR4)가 턴온된다.When the signal of the position sensing means 140 is changed by the rotor driving, a switching signal is applied from the output terminals P3 and P4 of the control means 120 so that the transistors TR1 and TR2 are turned off and the transistor TR3 is turned on. TR4) is turned on.
상기 트랜지스터(TR1,TR2)가 턴오프되는 순간, U상의 권선(w1,w2)에 축적된 에너지가 도 3의 ④와 같이 권선(w1), 권선(w2), 다이오드(D2), 다이오드(D1)를 통해 콘덴서(C)에 충전되고, 일부는 권선(w1), 권선(w4), 다이오드(D4), 다이오드(D1)를 통해 콘덴서(C)에 충전되며, 다른 일부는 권선(w1), 권선(w6), 다이오드(D6), 다이오드(D1)를 통해 콘덴서(C)에 충전된다.At the moment when the transistors TR1 and TR2 are turned off, the energy accumulated in the windings w1 and w2 of the U phase is wound in the winding w1, the winding w2, the diode D2, and the diode D1 as shown in ④ of FIG. 3. Is charged to the capacitor (C) through), and part is charged to the capacitor (C) through the winding (w1), winding (w4), diode (D4), diode (D1), the other part is winding (w1), The capacitor C is charged through the winding w6, the diode D6, and the diode D1.
도 3의 ④와 같은 회로 구성에서는 상기 트랜지스터(TR1,TR2)가 턴오프되는 순간 콘덴서(C)에 충전되는 에너지가 V상의 권선(w4)과 W상의 권선(w6)을 통해 소비되므로 V상의 권선(w4)과 W상의 권선(w6)에는 전류일부가 축적된다.In the circuit configuration as shown in ④ of FIG. 3, the energy charged in the capacitor C is consumed through the V phase winding w4 and the W phase winding w6 at the moment when the transistors TR1 and TR2 are turned off. A portion of the current is accumulated in the ww and the winding w6 of the W phase.
그리고, 상기 트랜지스터(TR1,TR2)가 턴오프되는 순간 트랜지스터(TR3,TR4)가 턴온되어 V상의 권선(w3,w4)에 전류가 흐르는데, V상의 권선(w4)에는 U상의 권선(w1,w2)에 축적된 에너지에 의해 전류 일부가 축적되어 있으므로 순간적인 토크 리플의 감소와 에너지 이용률을 높일 수 있다.At the moment when the transistors TR1 and TR2 are turned off, the transistors TR3 and TR4 are turned on so that a current flows in the windings w3 and w4 of the V phase. Because a part of the current is accumulated by the energy stored in), it is possible to reduce the instantaneous torque ripple and increase the energy utilization rate.
그리고, V상의 권선(w3,w4)에 흐르는 전류와 권선(w4)에 일부 축적된 전류에 의해 기자력이 발생하여 회전자가 구동하는데, 회전자의 구동에 따라 상기의 동작을 순차적으로 진행하여 회전자의 구동력이 발생한다.The rotor is driven by the current flowing through the windings w3 and w4 of the V-phase and the current accumulated in the winding w4, and the rotor is driven. The rotor is sequentially driven according to the driving of the rotor. Driving force is generated.
상기의 설명에서와 같이 본 발명에 의한 스위치드 릴럭턴스 모터의 고정자 권선방식에 의하면, 고정자의 3상(U상, V상, W상)을 연결하는 권선방식으로 1상이 여자되고 다음 상이 여자되는 순간 여자되었던 상의 권선에 축적된 에너지를 다음 상으로 분배하여 에너지 이용률 증가 및 토크 리플감소로 소음을 줄일 수 있다는 효과가 있다.According to the stator winding method of the switched reluctance motor according to the present invention as described above, the moment when one phase is excited and the next phase is excited by the winding method connecting three phases (U phase, V phase, W phase) of the stator. By distributing the energy accumulated in the windings of the excited phase to the next phase, noise can be reduced by increasing energy utilization and reducing torque ripple.
