摘要:
When the zero-crossing of one of the output signals of magnetic sensors has been detected, a rotation angle computing device identifies a magnetic pole sensed by the first magnetic sensor based on the other two output signals. Subsequently, the rotation angle computing device identifies the magnetic pole sensed by the second magnetic sensor and the magnetic pole sensed by the third magnetic sensor based on the magnetic pole sensed by the first magnetic sensor. After that, the rotation angle computing device corrects the amplitude of the output signal of each magnetic sensor based on the identified magnetic poles respectively sensed by the magnetic sensors. Then, the rotation angle computing device computes the electric angle θe of the rotor based on the corrected output signals.

当已经检测到磁传感器的输出信号中的一个的过零点时,旋转角计算装置基于其它两个输出信号识别由第一磁传感器感测的磁极。 随后,旋转角计算装置基于由第一磁传感器检测到的磁极来识别由第二磁传感器感测的磁极和由第三磁传感器感测的磁极。 之后,旋转角计算装置基于由磁传感器分别感测到的所识别的磁极来校正每个磁传感器的输出信号的振幅。 然后,旋转角度计算装置基于校正的输出信号计算转子的电角度θ。
