本文提出了一种使用带有集成磁力执行器的电主轴来主动减少颤振的新方法。基于先前的研究结果，描述了主动阻尼原型的设计。讨论了该解决方案的系统性能以及优点和缺点。为了消除已知的缺点，引入了新颖的致动器设计。这种新颖的方法将执行器绕组集成到定子铁芯中。接下来，提出了执行器和电机绕组的电和磁解耦策略。随后讨论了执行器的设计。通过解析和有限元分析 (FEA) 计算阻尼执行器的力产生和分布。通过这种新颖的方法，主动阻尼执行器的机械集成得到了显着简化。此外，与之前的解决方案相比，最大可达到的主轴功率提高了 150%。
This paper presents a novel approach for active chatter reduction using a motor spindle with integrated magnet actuators. Based on the results of previous studies the design of an active damped prototype is described. The system performance as well as the benefits and drawbacks of this solution are discussed. In order to eliminate the known drawbacks a novel actuator design is introduced. The novel approach integrates the actuator windings into the stator core. Next, strategies for electric and magnetic decoupling of the actuator and motor windings are presented. Subsequently the actuator design is discussed. The force generation and distribution of the damping actuator are calculated via analytical and finite elements analysis (FEA). With the novel approach the mechanical integration of the active damping actuators is simplified significantly. Additionally, the maximal attainable spindle power is increased up to 150% in relation to the previous solution.
