H2W技术开发了几种高扭矩旋转音琴致动器，否则称为有限的角度扭矩电动机或拉特。TWR-015-346--2型号设计用于允许低移动质量（每条线圈68g）和惯性，以及双独立线圈，以允许两个独立的运动型材或将线圈耦合在一起以加倍扭矩输出。This rotary voice coil actuator can generate a continuous torque of 185 in.-oz [1.29 N-m] and a peak torque of 555 in.-oz [3.88 N-m] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off) in each coil on a 4 in. [102 mm] rotation arm. By coupling the coils together, the continuous torque doubles to 370 in.-oz [2.58 N-m] with a peak torque of 1110 in.-oz [7.75 N-m] at a 10% duty cycle.
The TWR-015-346-2RC has a total angular displacement of 15 degrees [0.26 radians] and a motor constant of 34.4 in.-oz/sqrt(watt) [0.24 N-m/sqrt(watt)] per coil or when coupled together the motor constant is 48.5 in.-oz/sqrt(watt) [0.34 N-m/sqrt(watt)]. The voice coil motor requires 1.33 A of continuous current per coil and 4.0 A of peak current per coil to generate the specified forces. The actuator fits in and envelope of 4.37 in. [111.1 mm] x 2.99 in. [75.9 mm] x 1.64 in. [41.5 mm].
移动线圈设计确保了由于线圈是湿伤口和自支撑的无滞回运动，并且非换向线圈允许无纹波运动而没有齿槽。音圈致动器设计成在磁铁和线圈组件中安装有安装规定。这允许轴承系统的整合以保持线圈和永磁场组件之间的间隙。旋转式音圈致动器非常适用于需要高扭矩和高速应用的应用。示例包括在扫描应用中驱动万向轴以及提供用于图像稳定的稳定扭矩。
