The design of brushless DC Motor and driving – system
Abstract:: Brushess dc motor is a new type DC motor which operates with electronic-commutated tachocircuit and is a new mechatronics product. The product has a wide range of advantages such as high reliability, long lifetime etc. recently, and it widely used in industry、agriculture and in the army.
The DC motor without coal brush is in a new style, with higher work efficiency. Less wear and lower noise. The better governing speed characteristic is kept and the mechanical touch between brushes and commutator is removed as well in brushless DC Motors. .the thesis mainly discusses basic principle .dive-system and It’s design of magnetic circuit, and analyzes It’s design checracterisitecs.
Key: Brushless DC motor ; driving –system; the design of magnetic circuit.；application foreground
