7、一、实验目的了解霍尔转速传感器的应用。二、基本原理利用霍尔效应表达式：UH＝KH·IB，当被测圆盘上装上N只磁性体时，圆盘每转一周磁场就变化N次。每转一周霍尔电势就同频率相应变化，输出电势通过放大、整形和计数电路计数就可以测量被测物体的转速。...三、实验器材主机箱、霍尔转速传感器、转动源。四、实验步骤1、根据图5-5将霍尔转速传感器安装于霍尔架上，传感器的端面对准转盘上的磁钢并调节升降杆使传感器端面与磁钢之间的间隙大约为2～3ｍｍ。2、在接线以前，先合上主机箱电源开关，将主机箱中的转速调节电源2～24v旋钮调到最小（逆时针方向转到底），接入电压表（显示选择打到

8、20v档），监测大约为１
