Abstract

The present disclosure provides a method for measuring bandwidth of linear motor, including the following steps: step S1: setting a frequency distribution of an excitation signal; step S2: with reference to a target displacement level, measuring a steady state displacement peak of a motor vibrator at each frequency point of the excitation signal, and obtaining a frequency response curve with reference to the target displacement level; step S3: according to the frequency response curve obtained in step S2, determining an upper frequency limit and a lower frequency limit with reference to the target displacement level, and obtaining a bandwidth of the linear motor by calculating a difference between the upper frequency limit and the lower frequency limit.
