摘要

   隨著家電業(yè)的發(fā)展迅速,在日常生活中,家電已經(jīng)成了必不可少的部分,家電的發(fā)展必然也將帶動作為家電組成部分之一的電機業(yè)的發(fā)展。電機業(yè)的發(fā)展已經(jīng)超過了百年歷史,以前更多的是在結(jié)構(gòu)上的設(shè)計變化,但隨著需求的不斷提高,電子技術(shù)和材料技術(shù)的不斷進步,在電機這一產(chǎn)業(yè)上必然也將產(chǎn)生新的變革。而在主流的電機中,DC電機所占有的市場已經(jīng)越來越大,在市場競爭力和發(fā)展前景上也遠遠的好于AC電機,由此對DC電機作出新的設(shè)計也就成為了必然。
     同時由于是產(chǎn)品開發(fā),必然有著設(shè)計的原則,原則上新產(chǎn)品的設(shè)計主要是技術(shù)部開發(fā),其他部門相對協(xié)助,同時全程跟進新產(chǎn)品的開發(fā)。開發(fā)是基于原有的電機基礎(chǔ),主要設(shè)計的環(huán)節(jié)集中在電機內(nèi)部PCB ASSY和轉(zhuǎn)子部分的設(shè)計。相對與其他部分,模具的開發(fā)工程比較大,開發(fā)后的收益也有一定的風險性,所以在模具上的開發(fā)暫不列入設(shè)計之中,在電機外殼上的設(shè)計主要是新注塑材料的投入使用與否與先進的材料技術(shù)的結(jié)合,同時還要考慮成本和是否符合ROHS規(guī)定。
 本文介紹了DC 電機的基本原理結(jié)構(gòu)和整個產(chǎn)品的開發(fā)過程。通過這個過程也可以初步的了解一個產(chǎn)品的開發(fā)過程,了解DC 電機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.
