Description
본 발명은 플랫타입 모터(FLAT TYPE MOTOR)에 관한 것으로, 더욱 상세하게는 회전자와 상호작용하여 이를 회전시키는 코일이 권선된 고정자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat type motor, and more particularly, to a stator wound with a coil for interacting with a rotor and rotating it.
일반적으로 플랫타입 모터는 코일이 권선된 고정자에 의해 형성된 자장과 상호작용하여 회전자가 회전함으로써, 회전토크를 얻는 것이다.In general, a flat type motor is obtained by rotating a rotor by interacting with a magnetic field formed by a stator in which a coil is wound, thereby obtaining rotational torque.
이러한 플랫타입 모터는 도 1에 보인 바와 같이, 하우징(1)의 내부에 자석(3a)이 등간격으로 구성된 평타입의 회전자(3)가 회전가능하게 마련되어 있고, 회전자(3)에는 일단이 하우징의 외부로 돌출되어 일체로 회전하는 회전축(4)이 압입되어 있다. 그리고 회전자(3)의 상부에는 코일(2a)이 권선되어 전압 인가시 자장을 형성하는 고정자(2)가 구성되어 있다.As shown in FIG. 1, such a flat type motor is provided with a rotatable rotor 3 of which a magnet 3a is formed at equal intervals inside the housing 1 so as to be rotatable, and once in the rotor 3. The rotating shaft 4 which protrudes out of this housing and rotates integrally is press-fitted. In the upper part of the rotor 3, a coil 2a is wound to form a stator 2 that forms a magnetic field when voltage is applied.
이와 같이 구성된 플랫타입 모터는 전원이 인가됨에 따라 고정자(2)에서 자장을 형성하고 이와 상호작용하여 자석(3a)이 설치된 회전자(3)가 회전함으로써, 회전토크를 얻게 된다.The flat type motor configured as described above forms a magnetic field in the stator 2 as the power is applied and interacts with the rotor to rotate the rotor 3 provided with the magnet 3a, thereby obtaining rotational torque.
한편, 이러한 일반적인 모터는 고정자(2)에 권선된 코일(2a)수가 많으면 회전토크는 커지게 되고 상대적으로 회전수(RPM)는 감소된다. 즉 코일(2a)의 권선수에 비례하여 회전토크는 증대하고, 회전수는 코일(2a)의 권선수에 반비례하여 증대한다.On the other hand, in such a general motor, when the number of coils 2a wound on the stator 2 is large, the rotational torque becomes large and the rotational speed (RPM) is relatively reduced. That is, the rotational torque increases in proportion to the number of turns of the coil 2a, and the rotational speed increases in inverse proportion to the number of turns of the coil 2a.
따라서 고정자(2)에 일정한 코일(2a)이 권선된 있는 플랫타입의 모터에 있어서, 고회전수영역과 저회전수영역의 효율을 동시에 향상시킬 수 있는 방법이 없기 때문에 고회전영역에서는 저토크가 발생하고, 저회전영역에서는 고토크를 발생하게 된다. 이러한 이유로 플랫타입 모터가 적용되는 기계구조에서 고회전영역과 저회전영역을 동시에 필요로 하는 경우에는 저회전영역에서 도 2에 보인 바와 같이 효율이 상당히 떨어지게 된다. 좀더 자세히 설명하면 회전수(RPM)와 회전토크의 직선곡선(이하 T-N 커브라 칭한다)에 대해 효율곡선이 하부에 형성된다.Therefore, in a flat type motor in which a constant coil 2a is wound around the stator 2, since there is no way to improve the efficiency of the high speed region and the low speed region at the same time, low torque occurs in the high rotation region. In low rotational area, high torque is generated. For this reason, when a high rotational area and a low rotational area are required at the same time in a mechanical structure to which a flat type motor is applied, the efficiency is considerably lowered as shown in FIG. 2 in the low rotational area. In more detail, an efficiency curve is formed below the linear curve of the rotational speed (RPM) and the torque (hereinafter referred to as T-N curve).
결국, 종래의 플랫타입 모터는 코일(2a)이 일정수 만큼 권선되어 자장을 형성하는 하나의 고정자(2)에 의해 평 타입의 회전자(3)가 회전하기 때문에 고회전수와 고회전토크를 동시에 만족하지 못함으로써, 이러한 성능을 동시에 요구하는 기계구조에서는 효율이 저하하게 된다.As a result, the conventional flat type motor satisfies the high rotational speed and the high rotational torque at the same time because the flat type rotor 3 is rotated by one stator 2 in which the coil 2a is wound by a predetermined number to form a magnetic field. Failure to do so results in lower efficiency in mechanical structures that require this performance at the same time.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 평 타입의 회전자 양단부에 코일의 권선수, 또는 직경을 달리하여 저항값이 다르게 구성된 상 하부고정자를 각각 설치하여, 상대적으로 코일이 많이 감겨진 상부고정자에 의해 회전자는 고회전토크를 얻고, 동시에 상대적으로 코일이 적게 감겨진 하부고정자에 의해 고회전수를 얻게 됨으로써, 고회전토크와 고회전수영역을 동시에 얻을 수 있게 되어 효율을 향상시키는 플랫타입 모터를 제공하는 것이다.The present invention is to solve this problem, the object of the present invention is to install the upper and lower stator respectively configured to the resistance value by varying the number of windings, or diameter of the coil on both ends of the flat type of rotor, the coil is relatively The rotor has a high rotational torque, and the rotor has a high rotational torque, and the high rotational speed is obtained by the lower stator, which has less coils, so that the high rotational torque and the high-speed range can be obtained simultaneously. To provide a motor.

이러한 목적을 달성하기 위한 본 발명은, 하우징의 내부에 회전가능하게 마련된 평타입의 회전자, 회전자의 상하부에 설치되며 자장을 형성하여 회전자를 회전시키는 상부고정자와 하부고정자를 구비하는 것을 특징으로 한다.The present invention for achieving this object is provided with a flat type rotor rotatably provided inside the housing, the upper and lower stators are installed in the upper and lower parts of the rotor to form a magnetic field to rotate the rotor It is done.
이하, 본 발명에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
도 3는 본 발명에 따른 플랫타입 모터의 전체적인 구조를 보인 개략적인 측단면도이다. 도 4은 본 발명에 따른 플랫타입 모터의 회전토크와 회전수를 나타낸 특성곡선이다.Figure 3 is a schematic side cross-sectional view showing the overall structure of a flat type motor according to the present invention. Figure 4 is a characteristic curve showing the rotation torque and the number of revolutions of the flat type motor according to the present invention.
이에 도시한 바와 같이 본 발명에 따른 플랫타입 모터는, 하우징(10)의 내부에 회전축(40)이 일체로 압입되어 있으며 등간격으로 자석(31)이 마련된 평타입의 회전자(30)가 회전가능하게 설치되어 있고, 이 회전자(30)의 상부와 하부에는 코일(21,210g)이 권선되어 전압 인가시 자장을 형성하는 상부고정자(20)와 하부고정자(200h)가 구성되어 있다.As shown in the flat type motor according to the present invention, the rotating shaft 40 is integrally press-fitted in the interior of the housing 10, the flat type rotor 30 is provided with a magnet 31 at equal intervals is rotated The upper stator 20 and the lower stator 200h, which are provided as possible, have upper and lower coils 21 and 210g wound around the rotor 30 to form a magnetic field when voltage is applied.
본 발명의 특징적인 구성으로, 상부고정자(20)는 코일(21)의 권선수가 하부고정자(200g)보다 많게 감겨져 고회전토크를 얻도록 회전자(30)의 상부에 설치되어 있고, 하부고정자(200h)는 코일(210g)의 권선수가 상부고정자(20)보다 적게 감겨져 고회전수를 얻도록 회전자(30)의 하부에 설치되어 있다.In the characteristic configuration of the present invention, the upper stator 20 is installed on the upper part of the rotor 30 so that the number of windings of the coil 21 is wound more than the lower stator 200g, to obtain a high rotational torque, the lower stator 200h ) Is installed at the lower part of the rotor 30 so that the number of windings of the coil 210g is less than the upper stator 20 to obtain a high rotational speed.
이와 같이 구성된 본 발명에 따른 플랫타입 모터는 전원이 인가됨에 따라 코일(21,210g)이 각기 다르게 권선된 상부고정자(20)와 하부고정자(200h)에서 자장이 형성되고, 이 자장과 평타입 회전자(30)의 자석(31)이 상호작용하여 회전가능하게 구성된 회전자(30)가 회전을 하게 된다.In the flat type motor according to the present invention configured as described above, a magnetic field is formed in the upper stator 20 and the lower stator 200h in which coils 21 and 210g are wound differently as power is applied, and the magnetic field and the flat rotor The magnets 31 of 30 interact with each other so that the rotor 30 rotatably configured rotates.
이 때, 본 발명의 특징적인 작용으로 회전자(30)는 코일(21)이 많이 감겨진 상부고정자(20)에 의해 큰 회전토크를 형성하고, 아울러 코일(210g)이 적게 권선된 하부고정자(200h)에 의해 큰 회전수를 얻게 된다.At this time, the rotor 30 in the characteristic operation of the present invention forms a large rotational torque by the upper stator 20, the coil 21 is wound a lot, and also the lower stator winding the coil (210g) less 200h), a large rotational speed is obtained.
즉 회전자(30)는 코일(21,210g)의 권선수에 비례하여 회전토크가 증대하고, 권선수에 반비례하여 회전수(RPM)가 증대된다. 따라서 본 발명에 따른 플랫타입 모터는 회전자(30)의 상부에 설치되어 코일(21)이 상대적으로 많이 권선된 상부고정자(20)에 의해 회전자(30)가 큰 회전토크를 형성하게 되고, 회전자(30) 하부에 설치되어 코일(210h)이 상대적으로 적게 권선된 하부고정자(200g)에 의해 회전자(30)는 회전수가 커지게 됨으로써, 도 4에 도시한 바와 같이 각 상 하부고정자(20,200h)에 의해서 각 T-N 곡선에 대해 각 효율곡선이 향상되어 전체적인 플랫타입 모터의 효율이 증대된다.That is, the rotational torque of the rotor 30 increases in proportion to the number of turns of the coils 21 and 210g, and the rotational speed RPM increases in inverse proportion to the number of turns. Therefore, the flat type motor according to the present invention is installed on the top of the rotor 30, the rotor 30 is formed by the upper stator 20, the coil 21 is wound a lot, the large torque is formed, As the rotor 30 is rotated by the lower stator 200g installed at the lower portion of the rotor 30 and the coil 210h has a relatively small winding, as shown in FIG. 4, each phase lower stator ( 20,200h) improves the efficiency curve for each TN curve, thereby increasing the efficiency of the overall flat type motor.
결국, 각기 코일(21,210g)이 다르게 권선된 상 하부고정자(20,200h)를 갖춘 본 발명에 따를 플랫타입 모터는 고회전수영역과 저회전수영역의 효율을 동시에 만족하기 때문에, 고회전영역과 저회전영역이 동시에 요구되는 기계구조에 있어서 본 발명에 따른 플랫타입 모터를 적용하게 되면 이의 효율이 향상되게 된다.As a result, the flat-type motor according to the present invention having the upper and lower stators 20,200h each coil 21,210g wound differently satisfies the efficiency of the high speed region and the low speed region at the same time, so that the high rotation region and the low rotation. When the flat type motor according to the present invention is applied to a mechanical structure requiring an area at the same time, its efficiency is improved.
이러한 기술적 사상은 코일의 권선수를 다르게 한 것에 국한하지 않고, 도시하지는 않았지만 상부 하부고정자에 권선되는 코일의 직경을 달리 구성하여 저항값을 변경하여도 본 발명에 따른 목적을 달성 할 수 있음은 물론이다.This technical idea is not limited to varying the number of windings of the coil, and although not shown, the object according to the present invention can be achieved by changing the resistance value by configuring the diameter of the coil wound on the upper lower stator. to be.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 플랫타입 모터는 회전가능하게 설치된 평타입의 회전자 상하부에 코일의 권선수가 다른 상 하부고정자를 각각 설치하였다.As described in detail above, in the flat type motor according to the present invention, upper and lower stators having different number of windings of coils are respectively installed on upper and lower rotors of a flat type rotatably installed.
따라서 코일이 상대적으로 많이 권선된 상부고정자에 의해 회전자는 고회전토크를 형성하게 되고 적게 권선된 하부고정자에 의해 회전자는 회전수가 향상됨으로써, 고회전토크와 고회전수영역을 동시에 만족하여 이의 전체적인 효율이 향상되는 이점이 있다.Therefore, the rotor forms a high rotational torque by the upper stator in which the coil is relatively wound, and the rotational speed is improved by the lower stator in which the coil is wound relatively. There is an advantage.
