摘要： A linear oscillating actuator system which is capable of canceling out the stator vibrations for driving a load with a minimum of vibrations. The system includes an oscillator carrying a permanent magnet as well as an output shaft for connection to the load. A stator assembly is incorporated within a housing and is configured to movably support the oscillator and to carry an electromagnet.
The electromagnet generates a magnetic field which interacts with the permanent magnet to reciprocate the oscillator relative to the stator assembly in a linear path. A balancer is added to the system for canceling out undesired stator vibrations. The balancer are commonly supported to the stator assembly to be driven thereby in parallel with the oscillator. The balancer is configured to have a mass generally equal to that of the oscillator and to be devoid of any output member. Thus, the oscillator and the balancer are driven in a counter reciprocating manner, thereby keeping the stator assembly free from counter-vibrations and therefore driving the output shaft with a maximum output power.

摘要翻译： 一种线性振荡致动器系统，其能够以最小的振动消除用于驱动负载的定子振动。 该系统包括承载永磁体的振荡器以及用于连接到负载的输出轴。 定子组件结合在壳体内并且构造成可移动地支撑振荡器并携带电磁体。 电磁体产生与永磁体相互作用的磁场，以使振荡器相对于定子组件在线性路径中往复运动。 平衡器被添加到系统中以消除不期望的定子振动。 平衡器通常支撑在定子组件上，由此与振荡器并联。 平衡器被配置为具有大体上等于振荡器的质量并且没有任何输出构件的质量。 因此，振荡器和平衡器以反向往复运动的方式被驱动，从而保持定子组件不受反作用振动，从而以最大输出功率驱动输出轴。
