一种估测马达转子位置的方法及估测马达转子位置装置在此揭露。估测方法包括：在第一估测角度下注入第一高频讯号至马达；在注入第一高频讯号至马达的情况下，产生马达的第一感测讯号；在第二估测角度下注入第二高频讯号至马达，其中第二估测角度不等于第一估测角度；在注入第二高频讯号至马达的情况下，产生马达的第二感测讯号；根据第一感测讯号与第二感测讯号，判断操作夹角的所在象限；以及根据第一感测讯号、第二感测讯号以及操作夹角的所在象限，得到转子位置。; generating a first sensing signal of the motor in a case that the first high frequency signal is injecting to the motor; injecting a second high frequency signal to the motor at a second estimating degree; generating a second sensing signal of the motor in a case that the second high frequency signal is injecting to the motor; determining a quadrant which an operating degree belongs to according to the first sensing signal and the second sensing signal; and, acquiring the rotor position according to the first sensing signal, the second sensing signal, and the quadrant which the operating degree belongs to. |
