【摘要】：马达作为一种电能到机械能的转换装置,在工业控制和家用电器等领域中的应用非常广泛。新型的三相直流无感马达取代传统的直流有刷马达,展现出越来越多的优势,成为近年来的发展趋势。本文详细研究了三相直流无感马达的运行原理和控制理论。针对其中关键的“反生电动势”检测技术和“无传感器启动”技术,建立了数学模型,分析其中的优缺点。以半导体BICMOS制造工艺为平台,使用Cadence环境,仿真并设计实现了一种三相直流无感马达驱动芯片AM9800。该电路应用“反生电动势端电压检测”技术和“三段式启动”技术,只需要极少的外围器件便可以高效的控制三相直流马达。实验验证,该系统实现方便,成本低,效率高,可靠性高。
[Abstract]:As a kind of conversion device from electrical energy to mechanical energy, motor is widely used in industrial control and household appliances. A new three-phase DC sensorless motor replaces the traditional DC brushless motor. Showing more and more advantages. In this paper, the operating principle and control theory of three-phase DC sensorless motor are studied in detail. The key technologies of "inverse electromotive force" and "sensorless startup" are discussed in this paper. The mathematical model is established and the advantages and disadvantages are analyzed. The semiconductor BICMOS manufacturing process is used as the platform and the Cadence environment is used. A three-phase DC sensorless motor driving chip AM9800is simulated and designed. The circuit uses the technology of "reverse EMF end voltage detection" and "three-stage start" technology. Only a few peripheral devices are needed to control the three-phase DC motor efficiently. Experimental results show that the system is easy to realize, low cost, high efficiency and high reliability.
