Sensorless position control: Designing with ripple counting
Ripple Counting Demo Video
About
Many industrial applications use external sensors for position feedback and speed regulation of brushed DC motors which are often costly, complex, and take up valuable PCB space.
许多工业应用使用外部传感器对有刷直流电机进行位置反馈和速度调节,这些传感器通常成本高、结构复杂,而且占用宝贵的 PCB 空间。
In this video we introduce TI’s latest brushed DC motor technology, ripple counting; a sensorless approach to motor position and speed control. Eliminating encoders, hall effect sensors, optical sensors, shunt resistors and external sense resistors saves significant BOM cost and board space.
在本视频中,我们将介绍德州仪器最新的有刷直流电机技术--纹波计数;一种用于电机位置和速度控制的无传感器方法。无需编码器、霍尔效应传感器、光学传感器、分流电阻器和外部感应电阻器,从而节省了大量的 BOM 成本和电路板空间。
