六相感应电机具有转矩脉动低、电机损耗小、电机极限容量大、能量密度高等一系列优点。本文基于三相感应电机αβ两相静止坐标系下的数学模型表达式，将六相双Y30°绕组感应电机空间磁场分布等效成2套三相电机绕组磁势在空间上的合成，推导出空间坐标6/2矢量变换表达式，并设计出六相双Y30°绕组感应电机矢量控制系统，采用速度外环、电流内环双环控制系统。通过理论分析及仿真，验证了本文电机数学模型、坐标变换、控制策略的有效性。
The six-phase induction motor has a series of advantages such as low torque ripple, low motor loss, large motor limit capacity, and high energy density. Based on the mathematical model expression of αβ two-phase stationary coordinate system of three-phase induction motor, the spatial magnetic field distribution of six-phase double Y30° winding induction motor is equivalent to the spatial synthesis of two sets of three-phase motor windings. Coordinates 6/2 vector transformation expression, and designed a six-phase double Y30° winding induction motor vector control system are given. The double loop control system of speed outer loop and current inner loop is adopted. Through theoretical analysis and simulation, the effectiveness of the mathematical model, coordinate transformation and control strategy of the motor is verified.
