Ring appears armature electro-acoustic transducer, abandoned plane ferromagnetic disk Diaphragm Park, began to use his ring on the armature and the bonding of non-ferrous magnetic Park tapered at the end of radiator to lower the quality of the sound output pressure to increase by 5 decibels, to extend the frequency range of about 500Hz, the successful design, moving iron type electro-acoustic transducer to achieve the ultimate performance.

1950年出现的环型衔铁电声换能器，摒弃了铁磁性平面园盘振膜，开始采用环状衔铁和粘接其上的非铁磁性园锥形辐射体来降底质量，使输出声压提高了5分贝，频率范围扩展了约500Hz，这一成功设计使动铁式电声换能器的性能达到了极致。

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。

The utility model relates to a double-purpose driving apparatus of medical X-ray machine with remote-control and direct-control, which belongs to medical equipment.The driving apparatus comprises a direct-current speed reducing motor whose output terminal is fixed with a ring electromagnet; an armature iron is arranged on the motor output shaft whose end is provided with a driven wheel meshes with the armature iron and rotates around the motor shaft.As the electromagnet is electrified, the armature iron is attracted and disengages from the driven wheel.With the driving apparatus, the remote control and the direct control of a non-remote controlled X-ray machine can achieve, increasing the working efficiency by 3 to 4 times and the economical benefits.

该实用新型涉及双重用途的驾驶仪器的医用X光机的远程控制程序，并进行直接控制，属于医疗equipment.the驾驶仪组成，直接电流减速电机，其输出端是固定的一个环电磁铁；电枢铁是安排在电动机输出轴，其终点就是提供一台四轮驱动的网格与电枢铁和周围旋转电机shaft.as电磁铁通电，电枢铁是吸引和脱离接触，从驱动轮随着驾驶仪器，远程控制，并直接控制的一个非遥控X光机，能做到的事，提高工作效率3至4倍和经济效益。
