摘要： In sensorless vector control performed through use of a rotation speed of a synchronous motor 6 and the position of a rotor, a positive current is caused to flow to a γ axis on the assumption that a “d” axis serving as a true magnetic axis is out of phase with the γ axis by only an angle of load θe, whereby torque which is proportional to iγ sin θe and directed toward the γ axis arises in the magnetic axis. Accordingly, a deviation between a d-q axis serving as a true magnetic axis and a γ-δ axis serving as a control axis is eliminated. Even if load is exerted on the motor, the γ axis serving as a control axis is constantly aligned with the “d” axis serving as the magnetic axis of the synchronous motor, thereby enabling excellent vector control.
摘要翻译：在通过使用同步电动机6的转速和转子位置进行的无传感器矢量控制中，假设以“d”为正磁轴的轴为正，则使正电流流向γ轴与γ轴异相仅具有负载角θe，由此在磁轴上产生与igammasinθe成正比且朝向γ轴的转矩。因此，消除了用作真磁轴的d-q轴与用作控制轴的γ-δ轴之间的偏差。即使负载施加在电动机上，作为控制轴的伽马轴与作为同步电动机的磁轴的“d”轴恒定对齐，由此能够进行良好的矢量控制。

摘要： A magnetic flux estimator 7 of a controller used for sensorless vector-controlling of an induction motor computes an estimated speed ωrest and an estimated phase θlest from input α-phase and β-phase voltage instructions Vα*, Vβ* and α-phase and β-phase currents isα, isβ. A speed corrector 8 receives these information items and determines a difference between a differential value output from a phase estimator and an additionally input slip angular speed; that is, a deviation ω′res. Further, a primary delay integral value is determined by subtracting a slip angular frequency ωs from the deviation, and the primary delay integral value is multiplied by a correction gain, to thereby produce a correction to be made on the estimated speed ωrest. Thus, a more accurate estimated speed ω″rest is obtained.
