torque ripple reduction through design and control

高性能消费电子产品的特征通常是消费者期望安静、几乎无噪音的操作。来自驱动电子设备的操作的噪声、电机中的电磁效应、来自叶轮叶片的抖振效应以及滚珠轴承内的机械摩擦都是可检测的并且是不希望的，这表示浪费能量、过度磨损和质量差的感觉。这个博士学位将全面解决这些噪声源使用电机磁性和驱动控制的耦合设计。

High performance consumer electrical goods are often characterised by an expectation from the consumer of quiet, almost noiseless operation. Noise from operation of the drive electronics, electromagnetic effects in the motor, buffeting effects from the impeller blades and mechanical friction inside ball bearings are all detectable and unwanted, representing wasted energy, excess wear and a perception of poor quality. This PhD will comprehensively tackle these noise sources using the coupled design of motor magnetics and drive control.
