In this paper, a DC pre-excitation strategy, which limits the starting current and enhances the electromagnetic torque via establishing the flux linkage before starting process, is proposed to the three-level inverter under analysis on the mechanism of the above large current.

该文在探究上述情况产生原因的同时，提出了一种应用于三电平变频器-电机系统的直流预励磁方案，在电机起动前预先建立起电机磁场，有效地遏制过大的起动电流。

The hoisting and slewing mechanisms of QTZ125 tower crane use wire-winding electric motors, and steady hoisting and slewing can be realized, Besides, it can provide high speed for light load and low speed for heavy load, working efficiently with little noise.

QTZ315塔机起升机构及回转机构均采用绕线电机，起升、回转平稳，可实现轻载高速，重载低速，工作效率高，噪音低等优点。

When profile shot remain in effect or alight from the absolute position, the electrical power will automatically reduce to about 20VA, both to save energy, but also reduce the electrical load and last longer enough.

当挡杆停留在起或落的绝对位置时，电机的功率会自动减低至约20VA，既节省能源，亦减低电机的负载，使用寿命更长够。

When the system starts, the speed outer ring saturats non-functional, the current inner ring plays a major role to regulate the starting current to maintain the maximum so that the speed linear change, to reach a given value; when it operates steadily, the speed negative feedback from the outer ring plays a major role ,to let the speed changes with the given speed voltage , at the same time the current inner ring regulates the armature current of motor adjustment to balance the load current.

该系统起动时，转速外环饱和不起作用，电流内环起主要作用，调节起动电流保持最大值，使转速线性变化，迅速达到给定值；稳态运行时，转速负反馈外环起主要作用，使转速随转速给定电压的变化而变化，电流内环跟随转速外环调节电机的电枢电流以平衡负载电流。
