摘要： A commutator for use with a DC motor or a DC generator. The parent metal of the segments of the commutator is formed with bulging portions which have their outer surfaces generally coextending with the outer surfaces of protecting portions for contacting with brushes. This commutator is manufactured by forming a cylinder of a plate of a conductive material, by forming a plurality of pawls on the circumference of the cylinder, by molding a boss of a synthetic resin in the cylinder, by forming a plurality of notches in one end of the cylinder, and by cutting the trunk of the cylinder into a plurality of slits to form a plurality of separate segments.

摘要翻译： 用于直流电动机或直流发电机的换向器。 换向器的段的母体金属形成有凸起部分，其凸出部分的外表面与用于与刷子接触的保护部分的外表面大致共同延伸。 通过在圆筒的圆周上形成多个爪，通过在圆筒中模制合成树脂的凸台，通过在一端形成多个凹口来形成导电材料的板的圆筒来制造该换向器 并且通过将气缸的躯干切割成多个狭缝以形成多个单独的段。
