本文介绍了一种新型的集成电机与相关的驱动器和无线传输的电力和信息（WTPI），这是有效地应用于自主主轴驱动的复杂工件加工技术。整体电机的电源由可分离的WTPI联轴器提供。此外，在耦合的初级侧进行变压和变频（VVVF）控制的计算，然后通过WTPI耦合的功率传输数据的重叠传输将频率命令传输到次级侧。在次级侧，使用双向可控的功率开关进行从感应的高频电压到电动机端电压的直接功率转换。通过改变初级侧的逆变器电压来调节端电压的幅度。这样，VVVF驱动器通过WTPI联轴器进行，从而为整体副主轴提供了复杂加工的自主性。
This paper describes the novel technology of an integral motor with the associated driver and wireless transmission of power and information (WTPI), which is effectively applied to autonomous spindle drive for the sophisticated workpiece machining. The power supply to the integral motor is made by way of a separable WTPI coupling. In addition, calculation for variable voltage and variable frequency (VVVF) control is done at the primary side of the coupling, and then the frequency command is transmitted to the secondary side by an overlapped transmission of the data on the power transmission through the WTPI coupling. At the secondary side, direct power conversion from the induced high-frequency voltage to the motor terminal voltage is conducted using a bidirectionally controllable power switch. The amplitude of the terminal voltage is adjusted by changing the inverter voltage at the primary side. In this way, the VVVF drive is made through the WTPI coupling, thus providing the integral subspindle with the autonomy for sophisticated machining.
