본 고안은 회전속도가 전원주파수에 완전히 비례하고 유도 전동기와 같은 슬립이 없는 동기전동기의 회전자를 개량한 고안에 관한 것이다.The present invention relates to a design that improves the rotor of a synchronous motor without a slip, such as an induction motor, when the rotational speed is completely proportional to the power frequency.

일반적으로 동기전동기용 회전자는 회전자 코어의 내부에 축설된 축의 외주에 영구자석이 설치한 구조로 되어있는바, 종래의 이러한 회전자는 금속으로 된 회전자 철심의 사이사이에 약간의 틈새를 두고 동판(로러바)을 끼워 넣어서 되는 것이므로 전동기의 수리등을 위한 전동기의 분해시 회전자를 분리시켜 일정장소에 보관하게되면 회전차 철심의 내부에 설치된 영구자석의 자력에 의해 각종 금속가루나 금속편등이 흡인되어 회전자 주위에 흡착되고 심지어는 틈새를 통해 내부에까지 홉인됨으로서 조립시 이들을 모두 털어내야 하는 번거러움을 수반하고 내부에까지 흡인된 금속편을 모두 털어내지 못하였을 경우 모타를 소손시키는등의 손실을 주게되는 폐단이 있었다.In general, the rotor for a synchronous motor has a structure in which a permanent magnet is installed on the outer periphery of an axis built in the rotor core. In the conventional rotor, the copper plate has a slight gap between the metal cores of the rotor. When the motor is disassembled for the repair of the motor, the rotor is separated and stored in a certain place, so that various metal powders or pieces of metal are attracted by the magnetic force of the permanent magnet installed inside the iron core of the rotor. It is adsorbed around the rotor and even hopped inside through the gap, which entails the trouble of having to shake off all of them during assembly and damages such as damaging the motor when the metal pieces sucked out inside cannot be shaken off. There was this.

본 고안은 이와같은 점을 감안하여 안출한 것으로 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been devised in view of the above, and will be described in detail based on the accompanying drawings as follows.

영구자석(1)을 내설한 회전자코일(2)의 로터바(3)(3')을 설치함에 있어서 회전자코어(2)의 양측단(2')(2")과 이들을 연결하는 로터바(3)(3')를 비자성체인 동 또는 알루미늄으로 성형하고 로터바(3)(3')의 내외면에 자성체인 금속부재(4)를 다이캐스팅하여 로터바(3)(3')가 매설되도록 일체로 성형하여서 되는 것이다.In installing the rotor bars (3) (3 ') of the rotor coil (2) incorporating the permanent magnet (1), both ends (2') (2 ") of the rotor core (2) and the rotor connecting them The bars (3) and (3 ') are formed of copper or aluminum, which is non-magnetic material, and die-casting the metal member (4), which is a magnetic material, on the inner and outer surfaces of the rotor bars (3) and (3') to form the rotor bars (3, 3 '). It is to be molded integrally so that is embedded.

도면중 미설명부호 5는 축이다.Reference numeral 5 in the drawings is an axis.

이와같이된 회전자코어(2)의 양측단(2')(2")과 로터바(3)(3')를 비자성체인 알루미늄 또는 동으로 미리 성형하고 로터바(3)(3')의 내외면에 자성체인 금속부재(4)를 다이캐스팅하여 로터바(3)(3')가 매설되도록 성행한 것이므로 로터바(3)(3')는 금속부재(4)로 된 회전자코어(2)의 내부에 은폐되어 외부에서 보이지 않을뿐 아니라 종래와 같이 틈새가 전혀없어 분해로 인한 보관시 회전자코어(2)의 외부에 금속가루등이 부착되어도 조립시 털어내기가 매우 용이할뿐 아니라 내부에까지 홉착될 우려가 없으므로 모타를 소손시킬 이유가 전혀 없는 것이다.Both ends 2 'and 2' of the rotor core 2 and the rotor bars 3 and 3 'are thus preformed with non-magnetic aluminum or copper, and the rotor bars 3 and 3' are The rotor bars 3 and 3 'are rotor cores 2 made of the metal member 4 since die casting of the metal member 4, which is a magnetic material, is performed to embed the rotor bars 3 and 3'. ) Is concealed inside and is not visible from the outside, and there is no gap as in the prior art, so it is very easy to shake off during assembly even if metal powder is attached to the outside of the rotor core (2) during storage due to disassembly. There is no reason to burn out the motor because there is no risk of getting stuck.

즉 본 고안은 로터바(3)(3')가 회전자코어(2')를 형성한 금속부재(4)의 내부에 매설되고 은폐됨에 따라 코어(2)의 외면이 매끈하고 틈새가 없어 금속가루등이 불어도 쉽게 털어낼 수 있고 또한 내부까지 침투되지 아니하므로 조립시간이 단축되고 모타를 소손시키는 경제적 손실을 해소할 수 있는 효과가 있으며 그 제작공정이 다이 캐스팅하여 일체로 주성하므로 제작이 매우 용이하고 손쉬워 제작시간을 단축할 수 있는 잇점이 있다.In other words, as the rotor bar 3 and 3 'are embedded and concealed inside the metal member 4 forming the rotor core 2', the outer surface of the core 2 is smooth and there is no gap. Even if the powder is blown off easily, it does not penetrate into the inside, and the assembly time is shortened, and the economic loss that damages the motor is eliminated.The manufacturing process is die casting, so it is very easy to manufacture. It is easy and can shorten the production time.
