Description
본 발명은 압축기용 모터에 관한 것으로서, 특히 극변환 모터 제어방법에 관한 것이다.The present invention relates to a motor for a compressor, and more particularly, to a method for controlling a pole conversion motor.
일반적으로 압축기는 내부 모터의 회전력을 이용하여 냉매를 압축하는 기기로서, 냉장고, 공조기 등에 사용된다.Generally, a compressor is a device that compresses a refrigerant by using a rotational force of an internal motor, and is used in a refrigerator, an air conditioner, and the like.
특히, 냉장고에 적용되는 압축기용 모터는 도 1과 같이, 2극(N/S)의 고정자와 회전자로 이루어지고, 제품 특성에 따라 차이가 있지만 정속운전(예를 들어, 3600rpm) 만이 가능하다.In particular, the compressor motor applied to the refrigerator is made of a stator and a rotor of two poles (N / S), as shown in Figure 1, but can vary only depending on product characteristics, but constant speed operation (for example, 3600rpm) is possible. .
한편, 냉장고는 대표적인 운전 모드로 급속냉각 모드, 표준운전 모드가 존재하는데, 실제 급속냉각 모드로 운전되는 시간은 실사용 시간의 10% 미만이고 그 이외의 시간은 표준운전 모드로 운전된다.On the other hand, the refrigerator has a rapid cooling mode and a standard operation mode as a typical operation mode, the actual time of operation in the rapid cooling mode is less than 10% of the actual use time, other times are operated in the standard operation mode.
이때 급속냉각 모드에서는 조절해야할 온도범위가 크므로 상기와 같이 모터를 고정된 속도 즉, 고속으로 운전하여 급속한 냉각이 이루어지도록 해야 하지만 표준운전 모드에서는 조절해야할 온도범위가 그다지 크지 않으므로 이러한 고속운전은 오히려 소음 및 제품에 무리를 주는 등 악영향만을 끼칠 뿐이다.At this time, in the rapid cooling mode, the temperature range to be adjusted is large. Therefore, the motor must be operated at a fixed speed, that is, high speed, to achieve rapid cooling as described above. It only affects the noise and harms the product.
그럼에도 불구하고 실제 냉장고에서 압축기용 모터는 동작모드에 상관없이 급속냉각 모드에 맞춰져 고속으로 운전된다.Nevertheless, in actual refrigerators, the compressor motor is operated at a high speed according to the rapid cooling mode regardless of the operation mode.
즉, 도 2와 같이, 종래에는 압축기 모터를 단일속도로 구동하는데, 급속운전 모드의 경우 듀티비를 '1'로하여 즉, 냉장고의 온도조건에 상관없이 계속 구동하였다. 그리고 표준운전 모드의 경우 적정 듀티비에 따라 압축기용 모터의 온/오프를 반복하여 운전하였다.That is, as shown in FIG. 2, the compressor motor is driven at a single speed in the related art. In the case of the rapid operation mode, the duty ratio is set to '1', that is, the compressor motor is continuously driven regardless of the temperature condition of the refrigerator. In the standard operation mode, the compressor motor was repeatedly operated on and off according to the appropriate duty ratio.
이상에서 설명한 종래 기술에 따른 압축기용 모터는 운전모드에 상관없이 고속으로 구동되므로 소음이 많이 발생하며, 해당 제품의 요동으로 인한 제품에 무리를 가하여 수명을 단축시키는 문제점이 있다.Since the compressor motor according to the related art described above is driven at a high speed regardless of an operation mode, a lot of noise is generated, and there is a problem of shortening the service life by adding a force to the product due to the shaking of the corresponding product.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 극변환 모터를 채용하여 해당 전기기기의 운전조건에 맞도록 저속/고속 구동함으로써 제품의 저소음화를 이룩하고 수명단축을 방지하기 위한 극변환 모터 제어방법을 제공하는데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, by adopting a pole conversion motor to drive the low speed / high speed to meet the operating conditions of the electric device to achieve a low noise of the product and to prevent the shortened life The purpose is to provide a conversion motor control method.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 극변환 모터 제어방법은 극변환 모터 제어방법에 있어서, 극변환 모터를 소정 운전조건에 따라 2극 또는 4극 구동하는 단계와, 극변환 모터를 2극 구동하다가 4극 전환조건이 되면, 기 설정 시간(t) 동안 해당 극변환 모터 구동을 정지시킨 후, 4극으로 구동시키는 단계와, 극변환 모터를 4극 구동하다가 2극 전환조건이 되면, 2극으로 구동시키는 단계를 포함하여 이루어지는데 그 특징이 있다.In the pole conversion motor control method according to the present invention for achieving the above object, in the pole conversion motor control method, the step of driving the pole conversion motor 2 or 4 poles according to the predetermined operating conditions, and the pole conversion motor 2 When the pole drive is a four-pole switching condition, the driving of the pole conversion motor is stopped for a predetermined time t, and then driven to four poles. It is characterized by including the step of driving to two poles.
이하, 첨부된 도면을 참조하여 본 발명에 따른 극변환 모터 제어방법을 설명하면 다음과 같다.Hereinafter, a pole conversion motor control method according to the present invention with reference to the accompanying drawings as follows.
도 3은 본 발명에 따른 극변환 모터를 나타낸 도면이고, 도 4는 본 발명에 따른 극변환 모터 제어방법을 나타낸 플로우 차트이며, 도 5는 본 발명에 따른 극변환 모터의 2극/4극 전환시 시간을 나타낸 타이밍도이다.3 is a view showing a pole conversion motor according to the present invention, Figure 4 is a flow chart showing a pole conversion motor control method according to the present invention, Figure 5 is a two pole / four pole conversion of the pole conversion motor according to the present invention A timing chart showing time time.
본 발명에 따른 극변환 모터는 도 3에 도시된 바와 같이, 회전자(20)와, 극변환(2극/4극)을 통해 모터의 고속/저속 구동을 수행하기 위한 고정자(10)를 포함하여 구성된다.As shown in FIG. 3, the pole conversion motor according to the present invention includes a rotor 20 and a stator 10 for performing high speed / low speed driving of the motor through pole conversion (2 poles / 4 poles). It is configured by.
이와 같이 구성된 본 발명에 따른 극변환 모터 제어방법을 도 4를 참조하여 설명하면 다음과 같다.The pole conversion motor control method according to the present invention configured as described above will be described with reference to FIG.
먼저, 소정의 운전조건이 결정되었는지 여부를 판단한다(S100).First, it is determined whether a predetermined driving condition is determined (S100).
상기 판단 결과(S100), 소정 운전조건에 따라 2극 구동이 결정되면, 상기 극변환 모터를 2극 구동시킨다(S200).As a result of the determination (S100), when the two pole driving is determined according to a predetermined driving condition, the pole conversion motor is driven to the second pole (S200).
이어서 상기 극변환 모터를 2극 구동시키는 동안 현재 운전조건이 4극인지 여부를 판단한다(S300).Subsequently, it is determined whether the current driving condition is 4 poles while driving the pole conversion motor 2 (S300).
상기 판단 결과(S300), 현재 운전조건이 4극이면, 기 설정 시간(t) 동안 상기 극변환 모터 구동을 정지시킨 후(S400), 4극으로 구동시킨다(S500).As a result of the determination (S300), if the current operating condition is four poles, after stopping the pole conversion motor driving for a predetermined time (t) (S400), it is driven to four poles (S500).
여기서 상기 극변환 모터가 2극으로 구동 중일 때, 해당 극변환 모터를 4극으로 전환하려면 도 5에 도시된 바와 같이, 소정 시간(t) 동안 극변환 모터 구동을 정지시켜 해당 극변환 모터가 2극에서 4극으로 전환시에 발생되는 소음 및 해당 전기기기의 요동을 감소시킨다.In this case, when the pole conversion motor is being driven by two poles, to switch the pole conversion motor to four poles, as shown in FIG. 5, the pole conversion motor is stopped for a predetermined time t so that the pole conversion motor is two. Reduces the noise and fluctuations of the electrical equipment when switching from pole to quadrupole.
한편, 상기 판단 결과(S300), 현재 운전조건이 4극이 아니면, 해당 극변환 모터를 2극 구동시키는 단계(S200)로 복귀하여 해당 단계를 수행한다.On the other hand, if the current operation condition is not four poles, the determination result (S300), and returns to step (S200) for driving the two poles of the pole conversion motor to perform the corresponding step.
그리고 소정의 운전조건에 따라 4극 구동이 결정되면, 해당 극변환 모터를 4극 구동시키고(S600), 현재 운전조건이 2극인지 여부를 판단한다(S700).When the 4-pole driving is determined according to a predetermined driving condition, the corresponding pole conversion motor is driven 4-pole (S600), and it is determined whether the current driving condition is 2-pole (S700).
상기 판단 결과(S700), 현재 운전조건이 2극이면 상기 극변환 모터를 2극 구동하는 단계(S200)를 수행하고, 현재 운전조건이 2극이 아니면 해당 극변환 모터를 4극 구동하는 단계(S600)로 복귀하여 해당 단계를 수행한다.As a result of the determination (S700), if the current operation condition is two poles, the step S200 of driving the pole conversion motor is performed, and if the current operation condition is not two poles, driving the pole conversion motor four poles ( Return to S600) to perform the step.
이상에서 설명한 바와 같은 본 발명에 따른 극변환 모터 제어방법은 극변환 모터 구동방식을 2극에서 4극으로 전환할 경우에 소정 시간 동안 극변환 모터를 정지시킨 후, 4극으로 전환하는 방식으로 저속/고속 구동함으로써 소음 및 제품 수명단축을 방지하여 제품의 신뢰성을 향상시킬 수 있다.As described above, the pole conversion motor control method according to the present invention stops the pole conversion motor for a predetermined time when switching the pole conversion motor driving method from two poles to four poles, and then switches to the four poles at a low speed. / High speed drive prevents noise and shortened product life, improving product reliability.
