Description

용량가변형 압축기용 모터{MOTOR FOR VARIABLE CAPACITY TYPE COMPRESSOR}MOTOR FOR VARIABLE CAPACITY TYPE COMPRESSOR}

본 발명은 모터에 관한 것으로서, 특히 냉장기기에서 사용되는 용량가변형 압축기용 모터에 관한 것이다.The present invention relates to a motor, and more particularly to a motor for a variable displacement compressor used in refrigeration equipment.

일반적으로 냉동 및 냉장용 기기의 압축기에는 단상유도모터가 사용되고 있으며, 그 구성을 살펴보면, 크게 고정자와 회전자로 구분할 수 있다.In general, single-phase induction motors are used in compressors for refrigeration and refrigeration equipment. Looking at the configuration thereof, the stator and the rotor may be classified.

이때 종래의 기술에 따른 고정자(10)는 도 1에 도시된 바와 같이, 원형으로 일정간격을 두고 슬롯(slot)(11)이 형성되고, 특히 보조권선만 감기는 슬롯(11) ⑤,⑥의 경우 다른 슬롯에 비해 작게 설계된다. 또한 전체 슬롯(11)은 X/Y 축을 기준으로 상/하/좌/우 4부분이 대칭형이므로, 우측 상단만 도시하고 나머지는 도시를생략한다.At this time, the stator 10 according to the prior art, as shown in Figure 1, the slot (slot) 11 is formed at a predetermined interval in a circular shape, in particular of the slot (11) ⑤, ⑥ winding only the auxiliary winding The case is designed smaller than other slots. In addition, since the entire slot 11 has four symmetrical upper / lower / left / right directions with respect to the X / Y axis, only the upper right side is shown and the rest is omitted.

상기 슬롯(11)중 ①번, ②번, ③번 및 ④번에는 모터의 정회전을 위한 주권선이 감기고 ③번, ④번, ⑤번 및 ⑥번에는 모터의 역회전을 위한 보조권선이 감긴다.①, ②, ③ and ④ of the slot 11, the winding winding for the forward rotation of the motor is wound, and ③, ④, ⑤ and ⑥ winding auxiliary winding for the reverse rotation of the motor All.

여기서 정회전(일방향 회전)을 위한 모터의 경우 기동특성 및 효율특성을 증대시키기 위해 주권선을 보조권선에 비해 굵은 코일 즉, 보조권선의 코일 두께에 비해 10 ~ 30% 정도 두꺼운 코일을 사용한다. 그리고 주권선의 코일 턴수를 보조권선에 비해 약 1.1 ~ 1.6배 수준으로 한다. 이때 굵은 코일을 사용하는 것은 토크를 크게 하기 위함이고 턴수를 많게 하는 것은 턴수가 전기적인 인덕턴스로서 전류 위상을 지연시키는 역할을 하기 때문이다. 다시 말해, 주권선에 의한 주전류의 위상지연을 크게 함으로 상대적으로 보조권선에 의한 보조전류의 위상이 주전류보다 90°정도 빠르게하여 최대 토크를 얻기 위함이다.Here, in the case of the motor for forward rotation (one-way rotation), in order to increase the starting characteristics and efficiency characteristics, the main winding uses a thicker coil than the auxiliary winding, that is, a coil about 10 to 30% thicker than the coil thickness of the auxiliary winding. In addition, the number of turns of the main winding is about 1.1 to 1.6 times that of the auxiliary winding. In this case, the use of a thick coil is to increase the torque, and to increase the number of turns is because the number of turns serves to delay the current phase as an electrical inductance. In other words, the phase delay of the main current by the main winding is increased so that the phase of the auxiliary current by the auxiliary winding is about 90 ° faster than the main current to obtain the maximum torque.

이와 같이 모터를 설계할 경우 어느 한 방향 예를 들어, 정방향에 대해서는 적정 수준 이상의 효율특성(80% 이상)을 발휘할 수 있지만, 반대 방향 즉, 역방향의 경우 정방향의 효율에 비해 약 60% 정도의 효율밖에 나지 않는다.When the motor is designed in this way, the efficiency characteristic (80% or more) of a certain direction, for example, in the forward direction can be exhibited at an appropriate level or more, but in the opposite direction, that is, in the reverse direction, the efficiency is about 60% of the efficiency in the forward direction. I can't go outside.

종래의 기술에 따른 압축기용 모터는 일방향 회전에 대해서만 효율특성을 만족하고 그 반대방향 회전에 대해서는 효율특성이 사용가능 수준 이하로 저하되어 사용할 수 없어 용도에 따라 별도의 모터를 사용해야하는 등 활용성 제한의 문제가 있다.The compressor motor according to the prior art satisfies the efficiency characteristics only in one direction rotation, and in the opposite direction, the efficiency characteristics are lowered below the usable level and cannot be used. There is a problem.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 정회전 및 역회전에 대해 적절한 효율 특성을 만족시킬 수 있도록 한 용량가변형 압축기용 모터를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a variable displacement compressor motor capable of satisfying an appropriate efficiency characteristic for forward rotation and reverse rotation.

본 발명은 회전자 그리고 권선을 감기 위한 슬롯이 원형으로 일정간격을 두고 배열된 고정자를 구비하고, 상기 고정자의 슬롯별로 정회전용 주권선 또는 역회전용 보조권선이 감기는 용량가변형 압축기용 모터에 있어서, 고정자의 전체 슬롯중 보조권선이 감기는 슬롯의 크기가 적어도 주권선이 감기는 슬롯의 크기 이상이며, 주권선과 보조권선의 권선비가 1(주권선): 1.02 ~ 1.40(보조권선)이 됨을 특징으로 한다.In the present invention, the rotor and the slot for winding the winding is provided with a stator arranged in a circular interval at a predetermined interval, in the motor for a variable displacement compressor in which the forward winding main winding or reverse rotation auxiliary winding winding for each slot of the stator, Among the stator's total slots, the size of the slot where the auxiliary winding is wound is at least the size of the slot where the main winding is wound, and the winding ratio of the main winding and the auxiliary winding is 1 (main winding): 1.02 ~ 1.40 (secondary winding). do.

이하, 첨부된 도면을 참조하여 본 발명에 따른 용량가변형 압축기용 모터의 바람직한 일실시예를 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of a motor for a variable displacement compressor according to the present invention in detail.

도 2는 본 발명에 따른 용량가변형 압축기용 모터의 고정자 구조를 나타낸 도면이다.2 is a view showing a stator structure of a motor for a variable displacement compressor according to the present invention.

본 발명은 정회전과 역회전에 대한 효율이 일정 수준 이상 즉, 80% 이상으로 하는 것이 핵심이다.In the present invention, the key point is that the efficiency of forward and reverse rotation is above a certain level, that is, 80% or more.

일차적으로 정회전에 대한 효율을 80% 이상으로 유지하기 위해 코일의 두께를 기존과 동일한 수준 즉, 주권선으로 사용되는 코일을 보조권선용 코일에 비해 10 ~ 30% 두꺼운 코일을 사용한다.In order to maintain the efficiency of forward rotation more than 80%, the coil is used at the same level as the existing coil, that is, the coil used as the main winding is 10 to 30% thicker than the coil for the auxiliary winding.

다음으로, 역회전에 대한 효율 또한 80% 이상으로 향상시키기 위해 코일 권선비를 기존과 다르게 한다. 즉, 종래기술의 경우 주권선과 보조권선의 권선비를 1.1 ~ 1.6 : 1로 하여 주권선에 보조권선 보다 많은 코일이 감긴데 반하여, 본 발명은 주권선과 보조권선의 권선비를 1 : 1.02 ~ 1.40로 하여 보조권선에 주권선 보다 많은 코일이 감기도록 한 것이다. 따라서 도 2와 같이, 보조권선에 더 많은 코일이 감기므로 보조권선에 해당하는 슬롯을 주권선에 해당하는 슬롯과 동일하거나 그 이상의 크기로 한다. 이와 같이 보조권선의 권선비를 높임으로서, 역회전 효율을 향상시켰다.Next, to improve the efficiency of the reverse rotation to more than 80% coil turns ratio is different from the existing. That is, in the prior art, the winding ratio of the main winding and the auxiliary winding is 1.1 to 1.6: 1, while more coils are wound on the main winding than the auxiliary winding, and the present invention sets the winding ratio of the main winding and the auxiliary winding to 1: 1.02 to 1.40. More coils are wound on the auxiliary winding than the main winding. Therefore, as shown in FIG. 2, since more coils are wound around the auxiliary winding, the slot corresponding to the auxiliary winding is equal to or larger than the slot corresponding to the main winding. In this way, by increasing the winding ratio of the auxiliary winding, the reverse rotation efficiency was improved.

상기 권선비는 모터를 상기 권선비에 따라 설계하고 정방향 및 역방향으로 구동한 실험결과에 따라 양쪽 방향 효율이 적정 수준 즉, 80% 이상이 되는 권선비를 선별한 것이다.The turns ratio selects turns ratios in which the efficiency in both directions is an appropriate level, that is, 80% or more, according to the experimental results of designing the motor according to the turns ratio and driving the motor in the forward and reverse directions.

결국, 코일의 두께를 기존 수준으로 유지하고 권선비 조절을 통해 정회전과 역회전에 대한 효율을 모터의 동작에 필요한 적정수준 이상이 되도록 한 것이다.As a result, the thickness of the coil is maintained at the existing level, and the winding ratio is adjusted so that the efficiency of forward and reverse rotation is higher than the proper level required for the operation of the motor.

본 발명에 따른 용량가변형 압축기용 모터는 정회전과 역회전 양방향에 대해 공통적으로 80% 이상의 효율특성을 나타내므로 회전방향 등의 동작특성 구별없이 다용도로 사용할 수 있는 효과가 있다.The variable capacity compressor motor according to the present invention has an efficiency characteristic of 80% or more in both the normal and reverse rotation directions, and thus can be used for various purposes without distinguishing operating characteristics such as rotational direction.
