본 고안은 상기 목적을 달성하기 위한 기술적 수단으로서, 전원공급기의 단자에 연결된 전선을 자석으로 형성된 코아에 올려진 모우터의 정류자에 연결하여 모우터의 회전력에 따라 전류, 전압을 측정할 수 있도록 한 구성으로 이루어지는 특징이 있다.The present invention is a technical means for achieving the above object, by connecting a wire connected to the terminal of the power supply to the commutator of the motor mounted on the core formed by a magnet to measure the current, voltage according to the rotational force of the motor There is a characteristic which consists of a structure.
이하, 첨부된 도면에 의하여 본 고안을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안의 정상작동여부 실험장치는 도면에서와 같이 전원공급기(10)와 모우터(12)를 전선(14)으로 연결 구성한다.Normal operation of the experimental device of the present invention is configured to connect the power supply 10 and the motor 12 by the wire 14 as shown in the drawing.
전원공급기(10)에서는 전압계(16)와 전류계(18)가 전면에 부착되어 상기 전압계(16)와 전류계(18)는 전기적으로 연결된 전자장치와 연결되고 있다.In the power supply 10, a voltmeter 16 and an ammeter 18 are attached to the front surface of the power supply 10, and the voltmeter 16 and the ammeter 18 are connected to an electrically connected electronic device.
그리고, 전원공급기(10)의 전면 하단에는 접지를 이루는 전원공급단자(20)(20a)가 마련되어 있으며, 전원공급단자(20)(20a)에는 전선(14)이 결속되어 있다.In addition, a power supply terminal 20 (20a) forming a ground is provided at the front lower end of the power supply 10, and a wire 14 is connected to the power supply terminals 20, 20a.
한편 모우터(12)는 코아(22)의 내장홈(24)에 설치되고 있으며 모우터(12)의 정류자(26)에는 전원공급단자(20a)와 연결되어 있는 전선(14)이 부착되어 구성된다.On the other hand, the motor 12 is installed in the internal groove 24 of the core 22, and the commutator 26 of the motor 12 is configured by attaching a wire 14 connected to the power supply terminal 20a. do.
이와같은 구성으로 이루어지는 본 고안은 모우터(12)를 정지한 상태에서 코아(22)의 내장홈(24)에 올려놓고 전원공급단자(20)(20a)에 연결된 전선(14)을 정류자(26)와 접속한 후 전원공급기(10)에서 전압을 조정하여 전원공급단자(20)(20a)에 전원을 공급한다.According to the present invention having the above configuration, the commutator 26 places the wire 14 connected to the power supply terminals 20 and 20a on the built-in groove 24 of the core 22 while the motor 12 is stopped. ) And supply power to the power supply terminals 20 and 20a by adjusting the voltage at the power supply 10.
다음으로 모우터(12)를 손으로 천천히 2회전시키면 코아(22) 부분에 자속이 발생되고 이때 발생하는 전류 및 전압을 전원공급기(10)에 마련된 전류계(18)와 전압계(16)로 측정하면 모우터(12)의 정상작동여부를 실험할 수 있어 안전한 사용을 이룰 수 있는 것이다.Next, when the motor 12 is rotated slowly by hand, magnetic flux is generated in the core 22, and the current and voltage generated at this time are measured by the ammeter 18 and the voltmeter 16 provided in the power supply 10.
