【摘要】：针对传统潜油电机需要配备减速器才能驱动潜油螺杆泵的不足,提出了一种驱动潜油螺杆泵的双分数槽集中绕组低速潜油电机,电机定子采用空间相距特定角度的两套分数槽集中绕组。根据特殊的绕组结构,对电机在不同时刻的磁势进行分析,表明电机能够产生恒定的电磁转矩。利用有限元法对电机进行二维瞬态场分析,得到了电机在空载和额定负载条件下的磁场分布及相关特性,结果验证了电机在电磁设计上的合理性。所设计电机可实现在不增大电机定子外径的情况下增加电机的极数,降低同步转速,有望实现潜油电机直驱潜油螺杆泵,从而有效降低整个采油系统的成本,抽油质量大为提升,对整个系统的节能具有重要意义。
[Abstract]:Aiming at the shortage of traditional submersible motor which needs to be equipped with reducer to drive submersible screw pump, a low speed submersible motor with double fractional slot concentrated windings is proposed to drive submersible screw pump. The motor stator adopts two sets of fractional slot concentrated windings with special space distance. According to the special winding structure, the magnetic potential of the motor at different times is analyzed, which shows that the motor can produce constant electromagnetic torque. The finite element method is used to analyze the two-dimensional transient field of the motor, and the magnetic field distribution and related characteristics of the motor under the condition of no-load and rated load are obtained. The results verify the rationality of the electromagnetic design of the motor. The designed motor can increase the number of poles without increasing the outer diameter of the stator of the motor, reduce the synchronous speed, and hopefully realize the submersible screw pump directly driven by the submersible motor, thus effectively reducing the cost of the whole oil recovery system. The pumping quality is greatly improved, which is of great significance to the energy saving of the whole system.
