Development of cogging-free linear actuators for force feedback applications

许多力反馈虚拟现实模拟器使用线性执行器。然而，现有的线性执行器在运行过程中存在明显的齿槽响应。这是一个重大的复杂性，因为力反馈反应应该感觉类似于现实中经历的力。在拟议的研究项目中，将开发一种无爬行的直线驱动器。这将通过重新设计磁铁填料和在电机中使用铁磁材料来获得均匀的磁场来实现，而不是开发额外的控制手段。新的无堵塞执行器技术的开发将支持Iris将销售从目前的力反馈飞行磁轭扩展到直升机循环和用于直升机模拟的运动平台的雄心，这些市场需要高精度的力反馈响应。此外，该项目还将直接为西海岸波浪计划开发可持续能源技术解决方案提供服务，为波浪能量转换器的开发提供经济高效的模拟器，该模拟器必须提供模仿实际系统反应的力反馈。

Many force feedback virtual reality simulators use linear actuators. However, available linear actuators sufferfrom a significant cogging response during operation. This is a significant complication since the forcefeedback response should feel analogous to the forces experienced in reality. In the proposed research project, acogging-free linear actuator will be developed. This will be achieved by redesigning the magnet packing andthe use of ferromagnetic material in the motor to obtain a uniform magnetic field rather than developing anadditional means of control.The development of the new clogging-free actuator technology will underpin Iris' ambition to expand salesbeyond its current niche market of force-feedback flight yokes into Helicopter Cyclics and motion platformsused for helicopter simulation which require high precision force-feedback response. In addition, the projectwill directly serve the West Coast Wave Initiative's development of a sustainable energy technology solution byproviding cost-efficient simulators for the development of Wave Energy Converters which must provide forcefeedback that mimics the reactions of the actual system.
