본 고안은 전동기의 자석에 관한 것으로서, 특히 첨심형 무정류자 전동기의 전류전환 불안을 해소하기 위한 전동기의 자석에 관한 것이다.The present invention relates to a magnet of an electric motor, and more particularly, to a magnet of an electric motor for relieving anxiety of current switching of an advanced non-rectifier motor.
종래의 전동기는 제1도에 도시된 바와 같이 회전자 요크(1)와, 상기 회전자 요크(1)에 장착된 회전력 발생용 자석(2)과, 상기 회전자 요크(1)에 장착되고 상기 회전력 발생용 자석(2)의 하단부에 착자된 속도 제어용 자석(3)과, 상기 회전력 발생용 자석(2)에 대향하도록 구성된 연자성 재질의 철심(4)과, 상기 철심(4)을 둘러싸고 있는 귄선(5)과, 인쇄회로기판(6)과, 상기 인쇄회로기판(6) 상에 장착되고 상기 회전력 발생용 자석(2)의 자속을 입력받는 홀더(7)로 구성된다.The conventional electric motor is mounted on the rotor yoke 1, the magnet for generating rotational force 2 mounted on the rotor yoke 1, and the rotor yoke 1, as shown in FIG. The speed control magnet 3 magnetized to the lower end of the rotation force generating magnet 2, an iron core 4 made of a soft magnetic material configured to face the rotation force generating magnet 2, and the iron core 4 are enclosed. It consists of a drawing line 5, a printed circuit board 6, and a holder 7 mounted on the printed circuit board 6 and receiving magnetic flux of the rotating force generating magnet 2.
상기와 같이 구성된 종래의 전동기는 권선(5)에 전류가 흐르면 철심(4)은 전자석이 되고, 제2도의 (a), (b)에 도시된 바와 같은 회전력 발생용 자석(2)과 속도 제어용 자석(3)에서 자속이 발생한다. 상기의 두 자속은 홀더(7)에서 감지되어 전류절환을 일으키며 회전자계를 발생시킨다.In the conventional electric motor configured as described above, when a current flows in the winding 5, the iron core 4 becomes an electromagnet, and the rotational force generating magnet 2 and speed control as shown in (a) and (b) of FIG. Magnetic flux is generated in the magnet 3. The two magnetic fluxes are sensed by the holder 7 to cause a current switching and generate a rotating magnetic field.
상기 홀더(7)에 유입되는 자속은 회전력 발생용 자석(2)에서 발생되는 자속(7')과 속도 제어용 자석(3)에서 발생되는 자속(7";)이 제2도의 (c)와 같이 합성된 파형이다.The magnetic flux flowing into the holder 7 includes the magnetic flux 7 'generated by the rotational force generating magnet 2 and the magnetic flux 7 "; generated by the speed control magnet 3 as shown in FIG. It is a synthesized waveform.
그러나, 상기한 종래의 전동기의 홀더에 유입되는 자속의 파형은 N극과 S극을 분별할 수 없는 불감영역이 넓게 나타난다. 따라서, 상기 불감영역에서는 전류절환의 불안현상이 발생하고 전동기 회전의 정속성이 낮아진다는 문제점이 있었다.However, in the waveform of the magnetic flux flowing into the holder of the conventional electric motor described above, a dead zone where the N pole and the S pole cannot be distinguished is wide. Therefore, in the dead zone, there is a problem in that an unstable phenomenon of current switching occurs and the constant speed of motor rotation is lowered.
따라서, 상기한 종래기술의 문제점을 해걸하기 위한 본 고안은 회전력 발생용 자석에서 발생되는 자속만이 홀더에 유입되어 정확한 전류절환이 이루어지고 회전의 정속성이 높아지는 전동기의 자석를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a magnet of an electric motor, in which only a magnetic flux generated from a rotating force generating magnet flows into a holder so that accurate current switching is achieved and the constant speed of rotation is increased. .
상기한 목적을 달성하기 위한 본 고안의 전동기의 자석은 회전력 발생용 자석과 속도 제어용 자석이 하나의 영구자석에 분리 착자된 전동기의 자석에 있어서, 상기 회전력 발생용 자석과 속도 제어용 자석의 경계면이 상기 두 자석과 변대향하도록 장착된 철심과 대향하는 영구자석의 하단 모서리에서 회전자 요크와 밀착된 영구자석의 반대면까지 일정한 기울기를 가지고 사선으로 형성된 것을 특징으로 한다.The magnet of the motor of the present invention for achieving the above object is a magnet of a motor in which a rotational force generating magnet and a speed control magnet are separately magnetized in one permanent magnet, and the interface between the rotational force generating magnet and the speed control magnet is the same. It is characterized in that it is formed diagonally with a constant inclination from the bottom edge of the permanent magnet facing the iron core facing the two magnets and the opposite side of the permanent magnet in close contact with the rotor yoke.
이하, 첨부한 도면을 참조하여 본 고안의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

And a speed control magnet 13 magnetized to a lower end of the rotation force generating magnet 12, an iron core 14 made of a soft magnetic material facing the rotation force generating magnet 12, and the iron core 14. The winding line 15, the printed circuit board 16, and the printed circuit board 16 are mounted, and the holder 17 receives the magnetic flux of the magnet 12 for generating the rotational force.
상기 회전력 발생용 자석(12)과 속도 제어용 자석(13)의 경계는 상기 두 자석과 면대향하도록 장착된 철심(14)과 대향하는 영구자석의 하단 모서리에서 회전자 요크(11)와 밀착된 영구자석의 반대면까지 일정한 기울기를 가지고 사선으로 형성된다.The boundary between the rotating force generating magnet 12 and the speed controlling magnet 13 is permanently in close contact with the rotor yoke 11 at the bottom edge of the permanent magnet facing the iron core 14 mounted to face the two magnets. It is formed diagonally with a constant slope to the opposite side of the magnet.
상기와 같이 구성된 본 고안의 전동기는 귄선(14)에 전류가 흐르면 철심(15)은 전자석이 되고 제4도에 도시된 바와 같이 회전력 발생용 자석(12)에서 발생되는 자속(17')이 홀더(17)에 입력되어 전류절환을 일으키고 회전자계를 발생시킨다.In the electric motor of the present invention configured as described above, when a current flows through the wire line 14, the iron core 15 becomes an electromagnet, and as shown in FIG. 4, the magnetic flux 17 ′ generated by the rotation force generating magnet 12 is a holder. Inputted to (17) causes current switching and generates a magnetic field.
상기한 본 고안에 의한 전동기의 자석은 회전력 발생용 자석에서 발생되는 자속이 홀더에 유입되므로 불감영역이 좁아지고 정확한 전류절환을 할 수 있으며 정속성을 향상시킬 수 있다는 효과가 있다.The magnet of the motor according to the present invention has the effect that the magnetic flux generated from the magnet for generating a rotation force flows into the holder, thereby narrowing the dead zone, enabling accurate current switching, and improving static speed.
