摘要

   随着家电业的发展迅速,在日常生活中,家电已经成了必不可少的部分,家电的发展必然也将带动作为家电组成部分之一的电机业的发展。电机业的发展已经超过了百年历史,以前更多的是在结构上的设计变化,但随着需求的不断提高,电子技术和材料技术的不断进步,在电机这一产业上必然也将产生新的变革。而在主流的电机中,DC电机所占有的市场已经越来越大,在市场竞争力和发展前景上也远远的好于AC电机,由此对DC电机作出新的设计也就成为了必然。
     同时由于是产品开发,必然有着设计的原则,原则上新产品的设计主要是技术部开发,其他部门相对协助,同时全程跟进新产品的开发。开发是基于原有的电机基础,主要设计的环节集中在电机内部PCB ASSY和转子部分的设计。相对与其他部分,模具的开发工程比较大,开发后的收益也有一定的风险性,所以在模具上的开发暂不列入设计之中,在电机外壳上的设计主要是新注塑材料的投入使用与否与先进的材料技术的结合,同时还要考虑成本和是否符合ROHS规定。
 本文介绍了DC 电机的基本原理结构和整个产品的开发过程。通过这个过程也可以初步的了解一个产品的开发过程,了解DC 电机的一些工作原理和性能。

ABSTRACT

 As the household appliance industries developing rapidly in everyday life and home appliances have become an indispensable part of the development of household electrical appliances, it will also be driven home appliances as a component of the electrical industry. Motor industry growth has exceeded 100-year history, before more of the structural design changes, but as demand continues to improve, electronic technology and materials technology progresses, in the electrical industry, it will inevitably have a new change. In the mainstream motor, DC motor market share has been growing, the market competitiveness and development prospects are far better than the AC motor; DC motor of this new design will become the inevitable.
 Moreover, due to product development, necessarily have design principles; the principle of a new product design is the development of technology, relative to assist other departments, meanwhile entire follow-up development of new products. Development is based on the original motor foundation, designed mainly concentrated in the areas of motor and the internal PCB ASSY part of the rotor design. Compared with other parts, the mold development engineering quite is big; the development of the proceeds also has certain risks. Therefore, the mold development will not be incorporated in the design, mainly is newly casts the material in the electrical machinery outer covering design the investment use or not and the advanced material technology union, at the same time, we should consider the cost and compliance with ROHS regulations.
 This thesis talked about the DC motor structure and the basic tenets of the entire product development process. Through this process also may be a preliminary understanding product performance history, understand the DC electrical machinery some principles of work and the performance.
 
Keywords: DC motor, PCB ASSY, design, product development
