Description

차량의 구동모터용 레졸버{RESOLVER FOR DRIVING MOTOR OF VEHICLE }Resolver for driving motor of vehicle {RESOLVER FOR DRIVING MOTOR OF VEHICLE}

본 발명은 차량의 구동모터용 레졸버에 관한 것으로서, 보다 상세하게는 차량의 구동모터용 레졸버의 스테이터 구조에 관한 것이다.The present invention relates to a resolver for a drive motor of a vehicle, and more particularly, to a stator structure of a resolver for a drive motor of a vehicle.

화석 연료의 고갈, 환경 오염 등의 문제를 해결하기 위하여 일렉트릭 차량 또는하이브리드 차량이 많은 주목을 받고 있다. 일렉트릭 자동차 또는 하이브리드 차량은 구동력을 제공하는 전기 모터를 구비하고 있다.Electric vehicles or hybrid vehicles are attracting much attention in order to solve problems such as exhaustion of fossil fuels and environmental pollution. Electric or hybrid vehicles are equipped with an electric motor that provides driving force.

전기 모터의 제어를 위해서 전기 모터에서 로터의 절대위치를 판독하는 레졸버(resolver)가 사용된다. 일반적으로 레졸버는 스테이터, 로터 및 회전 트랜스를 구비한다. 스테이터와 로터의 권선은 자속분포가 각도에 대하여 정현파가 되도록 분포되어 있다. 1차측 권선(입력측)에 여자 전압을 인가하고 축을 회전시키면 자기적 결합계수가 변화하여 2차측 권선(출력측)에 각각 캐리어의 진폭이 변화한 전압이 발생하는데, 이 전압은 축의 회전각도에 대하여 sin 및 cos 상태로 변화하도록 권선이 배열되어 있다. sin 출력과 cos 출력의 캐리어 진폭비를 판독하는 것에 의해 레졸버의 회전각도를 알 수 있게 된다.For the control of the electric motor, a resolver is used that reads the absolute position of the rotor in the electric motor. The resolver generally has a stator, a rotor and a rotary transformer. The windings of the stator and the rotor are distributed so that the magnetic flux distribution becomes a sine wave with respect to the angle. When the excitation voltage is applied to the primary winding (input side) and the shaft is rotated, the magnetic coupling coefficient is changed and the voltage of the carrier is changed on the secondary winding (output side), which is sin for the rotation angle of the shaft. And the windings are arranged to change to the cos state. By reading the carrier amplitude ratio of the sin output and cos output, the rotation angle of the resolver can be known.

도 1은 종래의 차량의 구동모터용 레졸버의 스테이터를 도시한 개략도이다. 도시된 바와 같이, 종래의 차량의 구동모터용 레졸버의 스테이터(10)는 로터(미도시)를 둘러싸는 스테이터 본체(1)와, 스테이터 본체(1)와 일체로 성형되어 스테이터 본체의 양 측면을 절연시키는 제 1 절연부재(2)와 제 2 절연부재(3)를 구비하고 있다. 이와 같은 종래의 차량의 구동모터용 레졸버는 일본 특허 공개공보 제2001-352733호에 개시되어 있다.1 is a schematic diagram showing a stator of a resolver for a drive motor of a conventional vehicle. As shown, the stator 10 of the resolver for a drive motor of a conventional vehicle is formed integrally with the stator main body 1 and the stator main body 1 surrounding the rotor (not shown), and thus both sides of the stator main body. And a first insulating member 2 and a second insulating member 3 for insulating each other. A conventional drive motor resolver for such a vehicle is disclosed in Japanese Patent Laid-Open No. 2001-352733.

그런데 종래의 차량의 구동모터용 레졸버의 스테이터(10)에서는 제 1 절연부재(2) 및 제 2 절연부재(3)가 스테이터 본체(1)와 일체로 성형되어 있기 때문에 제 1 절연부재(2) 및 제 2 절연부재(3)를 형성하는 과정에서 발생하는 고열에 의해 스테이터 본체(1)의 물성이 변화되어 스테이터 본체(1)가 손상되기 쉽다. 이에 따라 제품의 신뢰성이 저하된다.However, in the stator 10 of the resolver for a driving motor of a conventional vehicle, since the first insulating member 2 and the second insulating member 3 are integrally molded with the stator main body 1, the first insulating member 2 ) And the high temperature generated in the process of forming the second insulating member 3 change the physical properties of the stator main body 1, thereby easily damaging the stator main body 1. This reduces the reliability of the product.

Can improve the reliability of the product.
