【摘要】
無刷直流電動機是近年迅速興起的一種新型電機，它廣泛應(yīng)用與工業(yè)，農(nóng)業(yè)，以及軍事等領(lǐng)域。 無刷直流電動機既保持了直流電動機良好的調(diào)速控制特性，又消除了電刷和換向器的機械接觸。
本文是對無刷直流電動機做出深入的剖析與設(shè)計。無刷直流電動機是一種具有高效率、低磨損、低噪聲的新型直流電機機種.本設(shè)計在介紹無刷直流電動機設(shè)計中，關(guān)于相數(shù)、極數(shù)、槽數(shù)及繞組連接方式的選擇方法和應(yīng)遵從的規(guī)律.而且針對小功率直流電動機結(jié)構(gòu)特點和工作性能，在電樞反應(yīng)理論基礎(chǔ)上設(shè)計出功率為120w的無刷直流電動機，并對霍爾位置傳感器和無刷電動機的控制及驅(qū)動做了詳細的分析。

Design of Brushless DC motor
【Abstract】
Brushless DC motor is rapidly development new motor in the recently, and it widely used in industry、agriculture and in the army. The better governing speed characteristic is kept and the mechanical touch between brushes and commutator is removed as well in brushless DC Motors.
This paper intends to make a better on the Design of Brushless DC motor .The DC motor without coal brushless is in a new style, with higher work rate. Less wear and lower noise. This paper presents the method of selecting phase, slot number and winding connection type and introduces the laws that should be obey in the design of brushless DC motor. Also based on introducing the structure of a light power DC motor, a 120w light power DC motor is design according to the theory. Not only make a lot of analyzed about the Hall position sensor in this paper .but also the brushless DC’s controls and the driving-methods for brushless DC.
【Key words】 design brushless DC motor Hall position sensor
