作者研究了电时间常数的降低，目的是在移动磁体线性致动器（LA）中实现高响应。本文描述了原型LA的动子半径、槽宽和电时间常数之间的关系。动子半径从11 mm增加到13 mm，永磁体厚度从3 mm增加到4 mm，LA的电时间常数可降低30%，槽宽从3 mm增加到5 mm，LA的电时间常数可降低18%。
The authors examined the reduction in the electrical time constant with the aim of achieving high response in a moving magnet linear actuator (LA). This paper describes the relationship between the mover radius, the slot width, and the electrical time constant of the prototype LA. The electrical time constant of the LA can be decreased by 30% by increasing the mover radius from 11 mm to 13 mm and by increasing the permanent magnet thickness from 3 mm to 4 mm. It can also be decreased by 18% by increasing the slot width from 3 mm to 5 mm.
