Abstract

In this analysis, the B-H curve was attained and assumed by Z and R type curves. The B/sub max/, H/sub c/, the driving frequency and the demagnetizing factors are considered as parameters to solve a numerical solution. As the driving frequency increased from 4 kHz to 12 kHz-step 4 kHz-the output voltages increased from 147 mV to 446 mV in Z-type. The detection error due to the rotation angles are limited to +3 degrees. In the R type curve, the output voltages are in the range of 145 mV to 354 mV. As the coercive force H/sub c/, is increased, the output voltage increased slightly. Considering the demagnetizing factor, the output voltages are reduced, but the detection error is decreased greatly.

汽车电子罗盘传感器的理论分析

在本分析中，B-H曲线由Z型和R型曲线得到并假设。以B/sub max/、H/sub c/、驱动频率和退磁因子为参数求解数值解。当驱动频率从4 kHz增加到12 kHz-步进4 kHz时，输出电压从147 mV增加到446 mV为z型。由于旋转角度的检测误差被限制在+3度。在R型曲线中，输出电压范围为145 mV ~ 354 mV。随着矫顽力H/sub c/的增大，输出电压略有增大。考虑退磁因素，降低了输出电压，但大大降低了检测误差。
