一种国产无刷直流电机驱动电路的设计

Design of a Domestic Brushless DC Motor Drive Circuit

无刷直流电机是一种应用及其广阔的产品,由于其具有体积小、高输出功率、高效率、控制简单、能实现无级调速、运行速度范围宽、高可靠性和低维护要求等特点,被广泛应用于汽车电子、自动化、航空航天等各个领域。然而在中国,我们大多使用的无刷直流电机驱动电路中的芯片都依赖进口,几乎很少出现一款完完整整由我们自己国内制造的芯片设计的无刷直流电机驱动电路,驱动器,所以设计一款国产化无刷直流电机驱动电路,驱动器是非常有必要的。

Brushless DC motor motors is an application and broad product,since it has small volume,high output power,high efficiency,simple control,can realize stepless speed regulation,wide speed range,high reliability and low maintenance requirements and other characteristics,widely used in automotive electronics,automation,aerospace and other fields.In China,however,most of us use the brushless DC motor drive circuit of the chip are dependent on imports,rarely appear a whole made by our own domestic chip design of brushless DC motor drive circuit,drive,so design a localization of brushless dc motor drive circuit,the drive is very necessary.
