摘要： PURPOSE: An insulation protective commutator is provided to compensate deformation in a cut-out portion. CONSTITUTION: A cutting recess for accommodating a coil(130) is formed in a connection terminal part(125) of a commutator segment(120). A cut-out part is formed in the edge of the width of the connection terminal part in the longitudinal direction. The cut-out part is formed in both end parts of the width of the connection terminal part. The commutator segment is arranged in the circumference surface of a resin core(110) fixed to the circumference of a shaft(101). An insertion hole(111) for accommodating the commutator segment is formed in the circumferential surface of the resin core. An insulation part(113) insulating commutator segments is formed between the insertion holes.

摘要： PURPOSE: A braking device of handheld grinder is provided to secure a light and simple structure by performing braking by using the friction force between magnetic material and an electromagnet. CONSTITUTION: A braking device of handheld grinder comprises a magnetic material(34), an elastic member(36), and an electromagnet(38). The magnetic material surrounds a driving shaft(14) and is combined with the driving shaft. The elastic member is fixed to the inner surface of a housing(12) facing the magnetic material. The electromagnet is connected between the elastic member and magnetic material using the elastic member. The electromagnet is magnetized using the flow of supply current for rotating the driving shaft. If the flow of supply current is quarantined, or a magnetic repulsive force between the magnetic material and electromagnet disappears, the driving shaft is stopped by the friction force for attaching the electromagnet to the magnetic body.
摘要翻译：目的：提供手持式研磨机的制动装置，通过使用磁性材料和电磁体之间的摩擦力进行制动，以确保轻巧简单的结构。构成：手持研磨机的制动装置包括磁性材料（34），弹性构件（36）和电磁体（38）。磁性材料围绕驱动轴（14）并与驱动轴组合。弹性构件固定到面向磁性材料的壳体（12）的内表面。使用弹性部件将电磁铁连接在弹性部件与磁性材料之间。使用用于旋转驱动轴的电源电流来使电磁体被磁化。如果隔离供电电流，或磁性材料与电磁铁之间的磁性排斥力消失，则驱动轴被用于将电磁铁附着在磁体上的摩擦力而停止。

摘要： 본 고안은 모터의 회전자와 철심슬롯을 일체형으로 몰딩하여 절연하도록 한 아마추어 일체형 몰딩 샤프트구조에 관한 것이다. 본 샤프트구조는 아마추어용 샤프트와; 방사방향으로 형성된 다수개의 치부를 갖는 철심슬롯이 축방향을 향하여 다수개가 적층되어 있으며, 상기 샤프트를 축방향으로 수용하는 철심부와; 절연을 위하여 상기 철심부와 상기 샤프트 사이에 게재되어 있고 다수개의 상기 치부를 향하여 일체형으로 연장된 고정다리부를 갖는 벌크성형복합재의 몰딩부와; 상기 치부를 향한 상기 고정다리부의 변형을 방지하기 위하여 상기 철심부의 가장자리에 위치한 철심슬롯의 치부 종단과 상기 몰딩부 어느 일측이 상대방을 향하여 요철결합되어 있는 다수개의 요철결합부를 포함한다. 이에 따라, 샤프트와 철심슬롯을 일체형으로 형성하여 열적인 변형을 방지하고 제조공정을 단축하여 생산성을 향상시키기 때문에 제품의 수명을 반영구적으로 향상시키고, 원가를 절감시켜 생산단가를 줄이는 효과가 있다.
