Description

모터motor
본 발명은 모터에 관한 것으로, 더욱 상세하게는 소비전력을 절감시킬 수 있도록 구조가 개선된 모터에 관한 것이다.The present invention relates to a motor, and more particularly to a motor having an improved structure to reduce power consumption.
일반적으로, 전기자동차의 동력발생수단은 모터이다. 상기 모터는 전류가 자기장 속에서 받는 힘을 이용하여 전기적 에너지를 기계적인 일로 바꾸는 장치로서, 도 1에 도시된 바와 같이, 도체에 다수의 코일이 권선되어 있는 회전자와 영구자석과 같이 자계를 형성시키는 계자를 포함하여 이루어진다. In general, the power generating means of the electric vehicle is a motor. The motor is a device that converts electrical energy into mechanical work by using a force received by a current in a magnetic field, and as shown in FIG. Including the field to make.
이러한 모터는, 전류가 흐르는 도체를 자기장 속에 놓으면 자기장의 방향에 수직한 방향으로 전자력이 발생하여 플레밍의 왼손법칙에 의해 회전됨으로써, 동력을 창출하게 된다.In such a motor, when a current-carrying conductor is placed in a magnetic field, an electromagnetic force is generated in a direction perpendicular to the direction of the magnetic field, thereby rotating by Fleming's left hand law, thereby generating power.
상기 전자력의 크기는 자계의 세기와 전류의 크기와 코일의 길이에 비례하게 되는데, 일반적으로 모터는 상기 전류의 크기를 조절함으로써 그 모터의 회전을 제어하게 된다.The magnitude of the electromagnetic force is proportional to the strength of the magnetic field, the magnitude of the current, and the length of the coil. In general, the motor controls the rotation of the motor by adjusting the magnitude of the current.
그러나, 모터가 채용되는 일반적인 제품과는 달리 전기자동차의 경우 무거운 중량을 가지는 차체를 상기 모터로 이동시켜야 하기 때문에, 모터에 회전력을 전달하기 위해서 큰 전류를 인가해 주어야 한다.However, unlike a general product in which a motor is employed, in the case of an electric vehicle, a vehicle having a heavy weight needs to be moved to the motor. Therefore, a large current must be applied to transmit the rotational force to the motor.
결국, 배터리에 저장된 전기의 빠른 소모로 대용량 배터리의 사용이 요구되고 배터리에 전기를 공급하기 위한 연료전지의 교체주기가 빨라지게 되는 문제점이 있다.As a result, there is a problem in that the use of a large capacity battery is required due to the rapid consumption of electricity stored in the battery, and the replacement cycle of the fuel cell for supplying electricity to the battery is accelerated.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 동일한 전류에 의해서도 상대적으로 큰 회전력을 얻을 수 있게 됨으로써 소비전력을 절감시킬 수 있는 모터를 제공하고자 하는 것이다.The present invention has been made to solve the above problems, an object of the present invention is to provide a motor that can reduce the power consumption by being able to obtain a relatively large rotational force even by the same current.
상기 목적을 달성하기 위한 본 발명은 전류가 자기장 속에서 받는 전자력을 이용하여 전기적 에너지를 기계적인 일로 바꾸기 위한 것으로, 도체에 다수의 코일이 권선되어 있는 회전자; 상기 전자력을 발생시키기 위해 자계를 형성시키며, 상기 전자력의 크기를 조절할 수 있도록 상기 회전자에 대해 접근 및 이격가능하게 설치되는 복수의 마그네트; 및 상기 각 마그네트를 상기 회전자에 대해 상대이동시키기 위한 이동수단;을 포함하여 이루어지는 것을 특징으로 한다.The present invention for achieving the above object is to convert the electrical energy into mechanical work by using the electromagnetic force of the electric current received in the magnetic field, the rotor is wound a plurality of coils in the conductor; A plurality of magnets that form a magnetic field to generate the electromagnetic force, and are installed to be accessible and spaced apart from the rotor to adjust the magnitude of the electromagnetic force; And moving means for relatively moving the magnets with respect to the rotor.

상기 각 제1링크의 일단부는 상기 마그네트들 중 어느 하나에 연결되고, 상기 각 제2링크의 일단부는 상기 제1링크가 연결된 어느 하나의 마그네트에 인접한 다른 하나의 마그네트에 연결되며, 상기 각 제1링크와 제2링크의 타단부는 힌지결합되어 있으며, 상기 이동경로 규제유니트는: 상기 제1링크와 제2링크의 타단부가 결합되어 있는 힌지축에, 그 힌지축과 함께 상기 하우징의 반경방향을 따라 이동가능하게 결합되고, 상기 마그네트들과 동일한 개수를 가지는 복수의 이동부재들; 상기 각 이동부재의 반경방향 이동을 안내하기 위하여, 상기 하우징에 결합되며, 상기 하우징의 반경방향을 따라 길게 형성되고 상기 각 이동부재의 끝단이 삽입되는 복수의 가이드슬릿들이 형성되어 있는 이동규제판;을 구비하여서, 상기 구동원이 상기 마그네트들 중 어느 하나를 상기 하우징의 반경방향을 따라 이동시키는 경우에, 나머지 마그네트들이 함께 상기 회전자에 대해 접근 및 이격되도록 구성되는 것이 바람직하다.One end of each of the first links is connected to one of the magnets, and one end of each of the second links is connected to another magnet adjacent to one of the magnets to which the first link is connected. The other end of the link and the second link is hinged, and the movement path regulating unit comprises: a hinge axis to which the other end of the first link and the second link are coupled, together with the hinge axis, in the radial direction of the housing. A plurality of movable members movably coupled along and having the same number as the magnets; In order to guide the radial movement of each of the moving member, the movement control plate is coupled to the housing, is formed along the radial direction of the housing and a plurality of guide slits are inserted into the end of each of the moving member; In the case where the driving source moves any one of the magnets along the radial direction of the housing, the remaining magnets are preferably configured to be approached and spaced apart from the rotor together.
상기 각 마그네트는 원형의 하우징에 상대이동 가능하게 설치되고, 상기 이동수단은, 상기 각 마그네트를 상기 하우징의 반경방향을 따라 이동시키기 위한 복수의 실린더장치를 구비하도록 구성될 수 있다.Each of the magnets is installed to be movable relative to the circular housing, the moving means may be configured to include a plurality of cylinder devices for moving the respective magnets in the radial direction of the housing.
상기 각 마그네트는 상기 각 실린더장치의 로드에 결합되고, 상기 마그네트들 중 일부는 상기 회전자에 대해 접근 및 이격되게 하고 상기 마그네트들 중 나머지는 이동방지될 수 있도록, 상기 각 로드를 선택적으로 이동시키기 위한 압력분배기를 구비하는 것도 가능하다.Each magnet is coupled to a rod of each cylinder device, selectively moving each rod such that some of the magnets are approached and spaced apart from the rotor and the remaining of the magnets are prevented from moving. It is also possible to have a pressure divider for it.
상술한 바와 같은 구성을 가지는 본 발명에 의한 모터는 마그네트와 회전자 사이의 거리를 조절함으로써 모터의 회전력을 제어할 수 있도록 구성됨으로써, 소비전력을 절감시킬 수 잇는 효과를 가진다.The motor according to the present invention having the configuration as described above is configured to control the rotational force of the motor by adjusting the distance between the magnet and the rotor, thereby reducing the power consumption.
결국, 본 발명에 의한 모터가 전기자동차에 채용되는 경우에, 모터의 소비전력이 절감됨으로써, 대용량 배터리의 사용을 지양(止揚)할 수 있고 배터리의 교체주기를 연장시킬 수 있는 장점이 있다. As a result, when the motor according to the present invention is employed in an electric vehicle, the power consumption of the motor is reduced, so that the use of a large capacity battery can be avoided and the replacement cycle of the battery can be extended.

이들 도면에 도시된 바와 같이, 본 발명에 의한 모터는 전류가 자기장 속에서 받는 전자력을 이용하여 전기적 에너지를 기계적인 일로 바꾸기 위한 것으로, 회전자(11)와 복수의 마그네트들(12)과 이동수단을 포함하여 이루어진다.As shown in these drawings, the motor according to the present invention is for converting electrical energy into mechanical work by using an electromagnetic force of electric current received in a magnetic field. The rotor 11, the plurality of magnets 12, and the moving means It is made, including.
상기 회전자(11)는 도체에 다수의 코일이 권선됨으로써 형성되고, 동력전달축(18)이 상기 회전자(11)와 함께 회전가능하게 결합되며, 원판형의 하우징(13) 내부에 배치된다. 상기 동력전달축(18)은 전기자동차의 휠을 회전시키기 위하여 그 휠과 함께 회전가능하게 연결되어 있다.The rotor 11 is formed by winding a plurality of coils around a conductor, and a power transmission shaft 18 is rotatably coupled with the rotor 11 and is disposed in a disc-shaped housing 13. . The power transmission shaft 18 is rotatably connected with the wheel to rotate the wheel of the electric vehicle.
상기 복수의 마그네트(12)는 상기 전자력을 발생시키기 위해 자계를 형성시키며, 상기 회전자(11)에 대해 접근 및 이격가능하도록 상기 하우징(13)에 설치된다.The plurality of magnets 12 form a magnetic field to generate the electromagnetic force, and are installed in the housing 13 to be accessible and spaced apart from the rotor 11.
한편, 전자력의 크기는, 자계의 세기와 전류의 크기와 코일의 길이에 비례하게 되는데, 상기 자계의 세기는 자속밀도와 비례하게 되고, 상기 자속밀도는 코일의 주위 거리, 즉 상기 마그네트(12)와 회전자(11) 사이의 거리에 반비례하게 된다.On the other hand, the magnitude of the electromagnetic force is proportional to the magnitude of the magnetic field, the magnitude of the current and the length of the coil, the strength of the magnetic field is proportional to the magnetic flux density, the magnetic flux density is the peripheral distance of the coil, that is, the magnet 12 And inversely proportional to the distance between the rotor 11.
본 발명은, 전류의 크기에 의해 모터의 회전력을 제어하는 종래기술과는 달리 마그네트(12)와 회전자(11) 사이의 거리를 조절함으로써 모터의 회전력을 제어할 수 있도록 구성됨으로써, 소비전력을 절감시키고자 하는 것이다.The present invention, unlike the prior art that controls the rotational force of the motor by the magnitude of the current is configured to control the rotational force of the motor by adjusting the distance between the magnet 12 and the rotor 11, thereby reducing power consumption I want to save.
이러한 효과를 도출하기 위한 구체적인 구성으로, 상기 각 마그네트(12)는 상기 전자력의 크기를 조절할 수 있도록 상기 회전자(11)에 대해 접근 및 이격가능하게 설치된다. 즉, 도 3의 실선으로 도시된 바와 같이 상기 마그네트(12)들이 상기 하우징(13)에 밀착되어 있는 상태에서는, 그 마그네트(12)들과 회전자(11) 간의 거리가 상대적으로 길어져 전자력의 세기가 작아지게 되고, 도 3의 점선으로 도시된 바와 같이 상기 마그네트(12)들이 상기 회전자(11)에 접근되어 있는 상태에서는, 상기 마그네트(12)들과 회전자(11) 간의 거리가 짧아져 전자력의 세기가 커지게 된다.In a specific configuration for deriving such an effect, each magnet 12 is installed to be accessible and spaced apart from the rotor 11 to adjust the magnitude of the electromagnetic force. That is, in the state where the magnets 12 are in close contact with the housing 13, as shown by the solid line of FIG. 3, the distance between the magnets 12 and the rotor 11 is relatively long and the strength of the electromagnetic force is increased. Becomes small, and the distance between the magnets 12 and the rotor 11 becomes short when the magnets 12 are approaching the rotor 11 as shown by the dotted line of FIG. The strength of the electromagnetic force is increased.
본 발명은 상기 마그네트(12)들을 상기 회전자(11)에 대해 이동시키기 위한 이동수단을 구비한다. 상기 이동수단은 상기 각 마그네트(12)들을 각각 개별적으로 이동시킬 수 있도록 구성될 수 있으나, 상기 마그네트(12)들의 개수의 대응되는 복수의 구동원을 구비하여야 하는 등 구성의 간소화를 이룰 수 없게 되고 각 마그네트(12)의 개별 이동을 위한 제어구성이 복잡하게 이루어지게 되는 단점을 가진다. The present invention includes a moving means for moving the magnets 12 relative to the rotor 11. The moving means may be configured to individually move each of the magnets 12, but it is not possible to simplify the configuration, such as having to provide a plurality of driving sources corresponding to the number of the magnets 12, respectively. There is a disadvantage that the control configuration for the individual movement of the magnet 12 is made complicated.
따라서, 본 실시예에서는, 상기 마그네트(12)들을 하나의 구동원(19)에 의해 동시에 이동시키기 위한 구성이 마련되어 있다.Therefore, in this embodiment, the structure for simultaneously moving the said magnets 12 by one drive source 19 is provided.
상기 이동수단은, 복수쌍으로 이루어진 제1링크(14)와 제2링크(15)들을 구비한다. 즉, 상기 제1링크(14)와 제2링크(15)가 한 쌍으로 이루어져 있고, 이러한 한 쌍의 제1링크(14)와 제1링크(14)는 상기 마그네트(12)들에 대응되는 개수만큼 구비된다.The moving means comprises a plurality of pairs of first link 14 and second link 15. That is, the first link 14 and the second link 15 are formed in a pair, and the pair of first link 14 and the first link 14 correspond to the magnets 12. It is provided as many as.
