阅读说明：本技术 电机及其转子元件、转子元件的制造方法 (Motor, rotor element thereof and manufacturing method of rotor element ) 是由 李长鹏 张卿卿 吴琪 卡特瑞娜·斯维纳连科 陈国锋 于 2019-05-27 设计创作，主要内容包括：一种电机的转子元件(200)的制造方法,其是在增材制造打印装置(100)中执行的。该制造方法包括如下步骤：提供一个基板(154)至增材制造打印装置(100)的成型缸中,基板(154)上设置有至少一个容纳孔(154a)；将一个转轴头(212)设置在该容纳孔(154a)中,并在转轴头(212)上表面通过激光熔化出多个凹槽(212b)；在基板(154)上铺设金属颗粒,并在增材制造打印装置(100)中通入惰性气体,对金属颗粒进行激光扫描,使得金属颗粒按照转子元件(200)预定形状自下而上地逐层熔化为转子元件(200)的转轴主体(214)以及转子(220)。该制造方法简单,同时提高了转子元件(200)的性能。还涉及一种电机及其转子元件(200)。(A method of manufacturing a rotor element (200) of an electrical machine is performed in an additive manufacturing printing apparatus (100). The manufacturing method comprises the following steps: providing a substrate (154) into a forming cylinder of an additive manufacturing printing device (100), wherein at least one accommodating hole (154a) is formed in the substrate (154); arranging a rotating shaft head (212) in the accommodating hole (154a), and melting a plurality of grooves (212b) on the upper surface of the rotating shaft head (212) by laser; metal particles are laid on the substrate (154), inert gas is introduced into the additive manufacturing printing device (100), and laser scanning is performed on the metal particles, so that the metal particles are melted into the rotating shaft main body (214) and the rotor (220) of the rotor element (200) layer by layer from bottom to top according to the preset shape of the rotor element (200). The manufacturing method is simple, and the performance of the rotor element (200) is improved. It also relates to an electric machine and a rotor element (200) therefor.)
