Analysis and design of electromagnetic moving coil vibrationgenerators

摘要

Electromagnetic shakers for vibration test applications form aclass of electrical machine whose operating conditions generallycombine: (a) operation over a wide frequency range (e.g. 5 Hz to 2 kHz);(b) relatively high volt-amps (e.g. 10 kVA); (c) a high degree oflinearity between electrical input and mechanical output (e.g. less than1% harmonic distortion with sine input). Here, the authors present theanalysis and design of EM machine-based moving coil vibration generators
