这是设计好并调试通过了的智能负载电路原理图和PCB板图

应用背景这种编码部分是基于超声波sensor.we距离测量使用射频收发器通过RF发送距离减小电机的速度。此应用程序是用来避免accidents.this超声波传感器在这个项目中起着重要的作用。关键技术本项目是基于超声波传感器的接口8051.we需要转换为数字和模拟值转换后的值发送到8051.we需要外部ADC转换器0804 ic.since 8051没有内置的ADC转换器。我用射频技术。

资源描述This application note shows how to control a permanent magnet synchronous motor (PMSM) with the sensorless field-oriented control (FOC) algorithm, using an ARM® Cortex®-M0-based PSoC 4 device. The FOC algorithm is frequently used in motor control applications because it allows motors to operate with less noise and more stable torque output than other algorithms. Sensorless FOC adds the advantage of reducing the cost due to the absence of rotor position sensors. Sensorless FOC is used in many applications including consumer (air conditioner, refrigerator), industrial (blower, pump), and commercial (elevator, escalator) products.
