Abstract. The article discusses a multi-phase magnetostrictive actuator which is the executive part of a multi-phase mechanical vibration controller (MVC). The whole system contains several stages of magnetostrictive actuators and a dedicated vibration sensor. Each individual actuator is dedicated to operation with the same frequency and with an individually programmed phase shift. The controller enables the actuator to excite mechanical vibration in various media (including liquids) to ultrasound frequencies. This allowed to continuously maintain a selected construction in mechanical resonance whose frequency was determined in real time. The work is the continuation of research on the development of the Energy Harvesting (EH) methods by using magnetostrictive actuator – mechanical cross phenomena.
