이 고안은 릴럭턴스(Reluctance) 동기모터의 회전자에 관한 것으로서, 더욱 상세하게는 모터의 회전자 공극에서 정현파형의 플럭스(Flux)가 발생되게 하는 릴럭턴스 동기모터의 회전자에 관한 것이다.The present invention relates to a rotor of a reluctance synchronous motor, and more particularly, to a rotor of a reluctance synchronous motor which causes a sinusoidal flux to be generated in a rotor cavity of a motor.

종래의 회전자는 제1도의 (a), (b)에 나타낸 바와같이 얇은 규소강판을 여러장 겹쳐 형성한 로우터코어(1)에 마그네트(2a) ∼ (2d)가 4방향으로 고정되고, 상기 로우터코어(1)와 마그네트(2a) ∼ (2d)가 비자성체의 고정요크(3a)와 몰드몰(3b)로 동시에 몰딩되어 축(4)에 고정된 것이다.In the conventional rotor, as shown in (a) and (b) of FIG. 1, magnets 2a to 2d are fixed in four directions to a rotor core 1 formed by stacking a plurality of thin silicon steel sheets. The core 1 and the magnets 2a to 2d are simultaneously molded into the stationary yoke 3a and the mold mole 3b of the nonmagnetic material and fixed to the shaft 4.

이와같은 종래의 회전자는 마그네트(2c) ∼ (2d) 각각의 사이인 공극에서 제1도의 (b)와 같이 양측은 밀집되고 가운데 부분은 미약한 플럭스가 발생되므로 제3도의 (a)와 같이 사다리꼴에 가까운 풀럭스 파형이 형성되었던 것으로. 모터의 토오크 특성이 불균일하게 되어 모터의 성능저하 및 고정밀도 제어용 모터에 적합하지않은 문제점이 있었다.Such a conventional rotor has a trapezoidal shape as shown in (a) of FIG. 3 since both sides are densified and a weak flux is generated in the center portion as shown in (b) of FIG. 1 in the gap between each of the magnets 2c to 2d. A full flux waveform close to that was formed. There is a problem that the torque characteristics of the motor is non-uniform, so that it is not suitable for the motor performance degradation and high precision control motor.

이 고안은 상기의 문제점을 해결하기 위한 것으로, 이 고안의 목적은 회전자의 공극에서 정현파의 플럭스가 발생하도륵 하여 모터 트오크 특성을 균일하게 함으로써. 모터성능을 향상시키고 고정밀도 제어용 모터에 적합하도록 한 릴럭턴스 동기모터의 회전자에 있어서, 상기 로우터코어의 각 공극부위의 외주면에 반원홈이 형성되어 몰드물로 몰딩되고, 상기 고정요크의 각 모서리에서 공극쪽으로 간막이가 형성된 릴럭턴스 동기모터의 회전자에 있다.This invention aims to solve the above problems, and the object of this invention is to generate a sinusoidal flux in the void of the rotor, thereby making the motor torque characteristic uniform. In a rotor of a reluctance synchronous motor which improves motor performance and is suitable for a motor for high precision control, a semicircular groove is formed on an outer circumferential surface of each void portion of the rotor core and molded into a mold, and each corner of the fixed yoke In the rotor of the reluctance synchronous motor with a diaphragm formed toward the air gap.

이하, 이 고안의 일실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail by the accompanying drawings.

제2도는 이 고안에 따른 회전자의 평면도로서, 로우터코어(11)에 마그네트(2a) ∼ (2d)가 4곳에 설치되고, 상기 로우터코어(11)와 마그네트(12a) ∼ (12d)가 비자성체의 몰드몰(13b), 고정요크(13a)로서 몰딩고정되어 축(14)에 고정된다.2 is a plan view of the rotor according to the present invention, wherein the rotor cores 11 are provided with four magnets 2a to 2d, and the rotor cores 11 and the magnets 12a to 12d are non-magnetic. Molding is fixed as the mold mold 13b and the fixed yoke 13a of the adult, and fixed to the shaft 14.

상기 마그네트(2a) ∼ (2d)사이인 로우터코어(11)의 각 공극부위 외주면에는 반원홈(15a), (15b)이 형성되어 몰드물(13c)이 몰딩되고, 역시 비자성체인 고정요크(13a)의 각 모서리에서 공극쪽으로 간막이(16)가 형성되어 있다.Semicircular grooves 15a and 15b are formed on the outer circumferential surface of each of the rotor cores 11 between the magnets 2a to 2d to mold the mold 13c, which is also a non-magnetic fixed yoke ( At each corner of 13a), a partition 16 is formed toward the gap.

이와같은 이 고안은 각 마그네트(12a) ∼ (12d)사이인 공극에서 반원홈(15a),(15b)에 몰딩된 비자성체의 몰드물(13c)과 간막이(16)에 의하여 제2도와 같은 플럭스가 생기게 되므로 제3도의 (b)와 같이 정현파의 플럭스 파형을 갖게된다.This design has a flux as shown in FIG. 2 by a non-magnetic mold 13c and a diaphragm 16 molded in semicircular grooves 15a and 15b in the gap between the magnets 12a to 12d. Since is shown in (b) of Figure 3 has a sinusoidal flux waveform.

따라서 모터의 트오크특성이 균일해지게 됨에 따라 모터의 성능이 향상되고, 고정밀도 토오크를 요하는 제어용모터에, 적합하게 되는 고안인 것이다.Therefore, as the torque characteristic of the motor becomes uniform, the performance of the motor is improved, and the invention is suitable for a control motor requiring high precision torque.
