摘要
无刷直流电动机是近年迅速兴起的一种新型电机,它广泛应用与工业,农业,以及军事等领域。无刷直流电动机既保持了直流电动机良好的调速控制特性,又消除了电刷和换向器的机械接触。
本文是对无刷直流电动机做出深入的剖析与设计。无刷直流电动机是一种具有高效率、低磨损、,关于相数、极数、,在电枢反应理论基础上设计出功率为120w的无刷直流电动机,并对霍尔位置传感器和无刷电动机的控制及驱动做了详细的分析。
【关键词】设计无刷直流电动机霍尔位置传感器
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 mutator 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
