    • Axial error calculation unit is provided for estimating an axial error &Dgr;&thgr; between a d-q axis and a dc-qc axis by using Ld, Lq, Ke, Id*, Iq*, Idc and Iqc in a range of all rotational speeds except zero of a rotational speed command of a synchronous motor, Ld denoting an inductance on a magnetic pole axis d of the synchronous motor, Lq an inductance on a q axis orthogonal to the magnetic pole axis d, Ke a generated power constant of the motor, Id* a current command of the d axis, Iq* a current command on a q axis, Idc a detected current value on an assumed dc axis on control, and Iqc a detected current value on an assumed qc axis orthogonal to the assumed dc axis. Irrespective of presence of saliency, position sensorless control can be achieved in a wide range a low to high speed zone.
    • 提供轴向误差计算单元,用于通过使用除了零的零以外的所有转速的范围内的Ld,Lq,Ke,Id *,Iq *,Idc和Iqc来估计dq轴和dc-qc轴之间的轴向误差Deltatheta 同步电动机的转速指令Ld表示同步电动机的磁极轴d上的电感,Lq是与磁极轴d正交的aq轴上的电感,Ke是电动机的发电功率常数,Id *电流 d轴的命令,Iq * aq轴上的电流指令,Idc是控制上假设的直流轴上的检测到的电流值,Iqc是与假定的直流轴正交的假设qc轴上的检测电流值。 无论存在显着性,可以在低速到高速区域的广泛范围内实现无位置传感器控制。
