虽然直接驱动电机（DD电机）已经有一段时间了，但现在在工业设备中使用的DD电机是一个相对较新的现象。由于DD电机的基本原理是在没有减速齿轮的情况下运行，并直接传递其旋转力，因此它们消除了由减速齿轮插入引起的问题，并且比传统的直流和交流伺服电机更快，更准确地定位。然而，长期以来，DD电机一直被认为难以控制，易受外部干扰和负载变化的影响，这阻碍了它们的广泛应用。DYNASERV DD电机，由横河电机公司于1987年开发和推出（现在由横河精密公司制造和销售），利用一种新的控制系统来克服DD电机的这些弱点，并被大量用于各种工业设备，如装配机器人，芯片贴片机和标签打印机。
Although direct-drive motors (DD motors) have been available for some time, the appearance of the DD motors now being used in industrial equipment is a relatively recent phenomenon. As DD motors by their basic principle operate without a reduction gear and transmit their rotational force directly, they eliminate the problems that result from interposition of the reduction gear and have enabled faster, more accurate positioning than is obtained with conventional DC and AC servo motors. However, for a long time DD motors have been considered difficult to control and susceptible to external disturbances and load variations which hinders their wider use. The DYNASERV DD motor, developed and introduced by Yokogawa Electric Corp. in 1987 (and now manufactured and marketed by Yokogawa Precision Corp.), exploits a new control system to conquer these weaknesses of the DD motor, and is being put to use in large numbers in a variety of industrial equipment such as assembly robots, chip mounters, and label printing m...
