摘要
感应电动机的矢量控制通过对定子电流的励磁分量和转矩分量进行解耦,从而实现对磁链和电磁转矩进行分别控制。然而,传统的感应电动机T型等效电路所表示的正弦稳态下感应电动机转子侧、定子侧及气隙所包含的电磁关系并不能明显地反映这种解耦情况。有鉴于此,在感应电动机的T型等效电路基础上,提出了一种感应电动机的T-I型等效电路。这种等效电路有助于更好地理解转子磁场定向的感应电动机矢量控制原理。
Through decoupling the torque and magnetic field of stator winding current, the flux and electromagnetic torque are controlled separately in vector control of induction motor. However, the electromagnetic relationship among rotor side, stator side and air gap, which is represented by the traditional T-shaped equivalent circuit, cannot obviously reflect this decoupling relationship. For this purpose, on the basis of the T-shaped equivalent circuit of the induction motor, the T-Ishaped equivalent circuit of the induction motor is proposed. This equivalent circuit contributes to a better understanding of rotor field oriented induction motor vector control theory.
