与传统直流电机相比,无刷直流(BLDC)电机有很多优点,如功率因数高,可靠性好,噪音小,寿命长,电磁干扰(EMI)小。由于没有换向器,无刷直流电机需要电流通路有换向器的功能。随着BLDC在机电系统中应用的增加,性价比高的无刷直流电机驱动器是提高产品竞争力所必需的。本文中介绍了一种高集成的无刷直流电机驱动器。
Brushless DC (BLDC) motors offer many advantages over traditional DC motors such as high power factor, good reliability, low noise, long life, and low electromagnetic interference (EMI). Because there is no commutator, brushless DC motor needs commutator function of current path. With the increasing use of BLDC in electromechanical systems, cost-effective brushless DC motor drives are necessary to increase the competitiveness of their products. This article describes a highly integrated brushless DC motor driver.
