Abstract
Description
본 발명은 극변환 모터에 관한 것으로서, 특히 극변환 모터의 고정자에 관한 것이다.The present invention relates to a pole conversion motor, and more particularly to a stator of a pole conversion motor.
일반적으로 극변환 모터 예를 들어, 2극/4극 모터는 고속구동시 2극모드로 동작하고 저속구동시 4극으로 동작하여 기존의 단극 모터와 달리 2단 속도제어가 가능하도록 한 모터로서, 고정자와 회전자 및 극변환을 위한 스위칭소자들로 구성된다.In general, a pole conversion motor, for example, a 2-pole / 4-pole motor operates in a 2-pole mode at high speed driving and a 4-pole at low speed driving, and thus, unlike a conventional single-pole motor, two-speed control is possible. It consists of stators, rotors and switching elements for pole conversion.
그리고 회전자의 회전을 위한 기동토크 및 회전토크를 발생시키기 위해 고정자의 각 슬롯(Slot)에는 모터의 특성에 맞도록 기설정된 턴수만큼 주권선, 보조권선 또는 보상권선이 소정 순서로 해당 슬롯에 감겨지는데, 토크 등을 고려한 모터의 설계특성상 슬롯별로 턴수가 다르게 된다.In order to generate the starting torque and the rotating torque for the rotation of the rotor, the main winding, the auxiliary winding or the compensation winding are wound in the corresponding slots in a predetermined order by a predetermined number of turns in accordance with the characteristics of the motor. The number of turns for each slot is different due to the design characteristics of the motor in consideration of torque.
그러나 종래의 기술에 따른 극변환 모터의 고정자는 도 1과 같이, 각 슬롯별 권선의 턴수에 상관없이 전체 슬롯(12)의 크기가 동일하므로 즉, 주권선이 감기는 슬롯(12)과 보조권선 및 보상권선이 감기는 슬롯(12)의 크기가 동일하므로 슬롯별 자속 밀도 차이 등으로 인하여 모터의 손실 요소 중의 하나인 고정자 손실을 초래한다.However, the stator of the pole conversion motor according to the prior art, as shown in Fig. 1, because the size of the entire slot 12 is the same regardless of the number of turns of each slot, that is, the main winding winding slot 12 and the auxiliary winding And because the size of the slot 12, the winding of the compensation winding is the same, due to the difference in magnetic flux density for each slot, etc., causes a stator loss, which is one of the loss factors of the motor.
종래의 기술에 따른 극변환 모터의 고정자는 각 슬롯별 권선 턴수에 상관없이 크기가 일정하여 고정자 손실을 초래하므로 모터 동작효율이 저하되는 문제점이 있다.The stator of the pole conversion motor according to the prior art has a problem that the motor operation efficiency is lowered because the size is constant regardless of the number of winding turns for each slot, causing stator loss.
따라서 본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 고정자의 슬롯의 크기를 권선의 턴수에 맞도록 변형하여 모터 동작효율 저하를 방지할 수 있도록 한 극변환 모터의 고정자를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, and provides a stator of a pole conversion motor to prevent the motor operating efficiency is reduced by modifying the size of the slot of the stator to match the number of turns of the windings. There is a purpose.
도 1은 종래의 기술에 따른 극변환 모터의 고정자의 구조를 나타낸 단면도1 is a cross-sectional view showing the structure of a stator of a pole conversion motor according to the prior art
도 2a 및 도 2b는 본 발명에 따른 극변환 모터의 고정자의 구조를 나타낸 단면도2A and 2B are cross-sectional views showing the structure of the stator of the pole conversion motor according to the present invention.
도면의 주요부분에 대한 부호의 설명Explanation of symbols for main parts of the drawings
21, 31: 고정자 22-1 ~ 22-3, 32-1 ~ 32-4: 슬롯21, 31: Stator 22-1 to 22-3, 32-1 to 32-4: Slot
본 발명은 주권선, 보조권선 또는 보상권선중 적어도 하나 이상이 소정 턴수만큼 권선된 다수개의 슬롯을 구비한 극변환 모터의 고정자에 있어서, 다수개의 슬롯들은 권선 턴수의 비율에 따른 면적을 갖도록 하는 것을 특징으로 한다.The present invention provides a stator of a pole conversion motor having a plurality of slots in which at least one of the main winding, the auxiliary winding, or the compensation winding is wound by a predetermined number of turns, wherein the plurality of slots have an area corresponding to the ratio of turns of the windings. It is done.
이하, 첨부된 도면을 참조하여 본 발명에 따른 극변환 모터의 고정자의 바람직한 일실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the stator of the pole conversion motor according to the present invention with reference to the accompanying drawings in detail as follows.
도 2a 및 도 2b는 본 발명에 따른 극변환 모터의 고정자의 구조를 나타낸 단면도이다.2A and 2B are sectional views showing the structure of the stator of the pole conversion motor according to the present invention.
먼저, 주권선과 보조권선 및 주보상권선을 구비한 극변환 모터의 고정자(21)는 도 2a에 도시된 바와 같이, 24개의 슬롯을 구비하는데, 이중 주권선만 감기는 슬롯(22-1)이 있고, 주권선과 주보상권선이 감기는 슬롯(22-2)이 있으며, 보조권선과 주보상권선이 감기는 슬롯(22-3)이 있다.First, the stator 21 of the pole conversion motor having the main winding, the auxiliary winding, and the main compensation winding has 24 slots, as shown in FIG. 2A. And a slot 22-2 in which the main winding and the main compensation winding are wound, and a slot 22-3 in which the auxiliary winding and the main compensation winding are wound.
따라서 주권선만 감기는 슬롯(22-1)에 비해 주권선과 주보상권선 또는 보조권선과 주보상권선이 감기는 슬롯(22-2)(22-3)의 크기 즉, 면적을 크게한다.Therefore, compared to the slot 22-1 winding only the main winding, the size of the main winding and the main compensation winding or the auxiliary winding and the main winding winding 22-2 (22-3), that is, the area is increased.
다음으로, 주권선과 보조권선과 주보상권선 및 보조보상권선을 구비한 극변환 모터의 고정자(31)는 도 2b에 도시된 바와 같이, 주권선만 감기는 슬롯(32-1)이 있고, 보조권선과 주보상권선이 감기는 슬롯(32-2)이 있고, 주권선과 주보상권선 및 보조보상권선이 감기는 슬롯(32-3)이 있으며, 보조권선과 주보상권선 및 보조보상권선이 감기는 슬롯(32-4)이 있다.Next, the stator 31 of the pole conversion motor having the main winding, the auxiliary winding, the main compensation winding and the auxiliary compensation winding has a slot 32-1 for winding only the main winding, as shown in FIG. 2B. There is a slot (32-2) in which the winding and the main compensation winding are wound, and there is a slot (32-3) in which the main winding, the main compensation winding and the auxiliary compensation winding are wound, and the auxiliary winding, the main compensation winding and the auxiliary compensation winding are wound. Has a slot 32-4.
따라서 주권선만 감기는 슬롯(32-1)에 비해 보조권선과 주보상권선이 감기는 슬롯(32-2)의 면적을 크게하고, 상기 보조권선과 주보상권선이 감기는 슬롯(32-2)에 비해 주권선과 주보상권선 및 보조보상권선이 감기는 슬롯(32-3) 또는 보조권선과 주보상권선 및 보조보상권선이 감기는 슬롯(32-4)의 면적을 더 크게 한다.Therefore, as compared with the slot 32-1 winding only the main winding, the area of the slot 32-2 in which the auxiliary winding and the main compensation winding are increased, and the slot 32-2 in which the auxiliary winding and the main compensation winding are wound. ), The area of the slot (32-3) in which the main winding, the main compensation winding and the auxiliary compensation winding are wound, or the slot 32-4 in which the auxiliary winding, the main compensation winding and the auxiliary compensation winding are wound, is made larger.
결국, 본 발명은 권선 턴수의 비율에 따라 슬롯의 면적을 결정하는 것이다.After all, the present invention is to determine the area of the slot in accordance with the ratio of the number of turns turns.
예를 들어, 권선 턴수의 비율이 1:1.2:1.3 일 경우 슬롯의 면적도 1:1.2:1.3으로 하고 권선 턴수의 비율이 동일한 경우 슬롯의 면적도 동일하게 한다.For example, if the ratio of turns turns is 1: 1.2: 1.3, the area of the slot is 1: 1.2: 1.3, and if the turns ratio is the same, the area of the slot is the same.
따라서 전체 슬롯의 자속 밀도가 모터의 동작특성에 맞도록 균일화되어 고정자 손실이 최소화된다.Therefore, the magnetic flux density of the entire slot is equalized to match the operating characteristics of the motor, thereby minimizing stator losses.
본 발명에 따른 극변환 모터의 고정자는 각 슬롯별 권선의 턴수에 비례하도록 슬롯의 크기가 결정되므로 고정자 코어 손실을 최소화하여 모터 동작효율을 향상시킬 수 있는 효과가 있다.The stator of the pole conversion motor according to the present invention has the effect of improving the motor operating efficiency by minimizing the stator core loss because the size of the slot is determined to be proportional to the number of turns of each slot winding.
