시동전동기의 회전자{Rotor of start motor}Rotor of start motor

본 발명은 자동차 등의 엔진 시동을 위하여 설치되는 시동전동기에 있어서, 상기 시동전동기의 구동력을 발휘하는 회전자의 축에 전동자용 연철판(라미네이션)을 설치하고 이의 외주에 자기력 발생용의 자석을 설치하여 상기 시동전동기의 회전자를 구성하므로써 상기 회전자 자기력의 소용돌이 흐름이나 웨지흐름(Wedge current)을 감소시키고 회전자의 효율을 향상시킬 수 있도록 한 시동전동기의 회전자에 관한 것이다.The present invention provides a starting motor provided for starting an engine of a vehicle, such as installing a soft iron plate (lamination) for an electric motor on an axis of a rotor that exerts a driving force of the starting motor and installing a magnet for generating magnetic force on the outer periphery thereof. The present invention relates to a rotor of a starter motor which can reduce the vortex flow or wedge current of the rotor magnetic force and improve the efficiency of the rotor by configuring the rotor of the starter motor.

일반적으로 자동차 등의 엔진에는 엔진의 시동과 관성을 이용하기 위하여 링기어가 설치된 플라이 휠을 설치하고 있으며 이 플라이 휠은 시동전동기에 설치된 피니언으로 회전시켜 엔진을 시동시키도록 되어있고, 상기 시동전동기는 밧데리로부터의 전원을 인가 받아 작동되는 전자 스위치에 의해서 회전자에 자기력이 발생되며 이 자기력에 의하여 상기 회전자가 구동력을 가지면서 피니언을 구동시키게 되고 이 피니언은 상기 링기어와 치합되어 엔진을 시동시킨 다음, 오버런닝 클러치에 의하여 다시 원위치되는 작동을 하도록 되어있다.In general, engines such as automobiles are provided with a flywheel in which a ring gear is installed in order to use engine starting and inertia, and the flywheel is configured to start the engine by rotating with a pinion installed in the starting motor. The magnetic force is generated on the rotor by an electronic switch that is operated by the power supplied from the battery. The magnetic force causes the rotor to drive the pinion with the driving force. The pinion is engaged with the ring gear to start the engine. It is designed to be operated again by the overrunning clutch.

한편, 상기와 같이 작동되는 시동전동기에 있어서, 종래의 회전자는 상기 시동전동기의 하우징 내주에 필드코일을 설치하고 이의 내측에는 축상에 자석을 일체형으로 설치하거나 상기 축과 분리되는 로터에 자석을 설치하여 구성된 회전자를 설치하도록 되어 있었으며, 상기 필드코일에 전원이 인가되면, 이 코일에서 발생되는 자기력과 상기 회전자의 자석과의 사이에서 상호 유도작용이 형성되어 상기 회전자가 구동되도록 되어 있었다.On the other hand, in the starter motor operated as described above, the conventional rotor is provided with a field coil on the inner circumference of the housing of the starter motor and the magnet is installed in the rotor integrally with the shaft or inside the rotor is separated from the shaft by The rotor was configured to be provided. When power was applied to the field coil, mutual induction was formed between the magnetic force generated in the coil and the magnet of the rotor to drive the rotor.

그러나, 상기와 같은 종래의 것은 상기 자석이 회전자축에 절연되지 않은 상태에서 직접설치 방식으로 설치되도록 구성되어 있었기 때문에 상기 회전자의 자기력흐름이 상기 회전자의 축을 통하여 누설되는 일이 발생되고 있었으며 상기 누설된 자기력에 의하여 유도작용을 간섭하게 되어 상기 회전자의 구동력을 약화시키게 되고 상기 자기력에 소용돌이 상태로의 흐름현상이 발생되는 폐단이 있었고 이 현상에 의하여 상기 시동전동기의 출력이 약화되는 점 등의 문제점이 있었다.However, in the related art, since the magnet is configured to be installed in a direct installation manner without being insulated from the rotor shaft, the magnetic force flow of the rotor leaks through the shaft of the rotor. Due to the leakage of magnetic force, the induction action is interrupted, which weakens the driving force of the rotor, and there is a closed end of the flow phenomenon in the vortex state of the magnetic force, and the output of the starting motor is weakened by this phenomenon. There was a problem.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 자동차 등의 엔진 시동을 위하여 설치되는 시동전동기에 있어서, 상기 시동전동기의 구동력을 발휘하는 회전자의 축에 전동자용 연철판인 라미네이션을 설치하고 이의 외주에 자기력 발생용의 자석을 설치하여 상기 시동전동기의 회전자를 구성하므로써 상기 회전자 자기력의 소용돌이 상태의 흐름을 감소시키고 회전자의 효율과 시동전동기의 출력을 향상시킬 수 있도록 한 시동전동기의 회전자를 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and in a starter motor installed for starting an engine such as a car, a lamination of a soft iron plate for an electric motor is placed on an axis of a rotor that exerts a driving force of the starter motor. And a magnet for generating a magnetic force on the outer periphery thereof to configure the rotor of the starting motor, thereby reducing the flow of the vortex of the rotor magnetic force and improving the efficiency of the rotor and the output of the starting motor. It is intended to provide a rotor of the electric motor, which will be described in detail with reference to the accompanying drawings and embodiments below.
