Title:
TEST DEVICE, HEDGE TRIMMER, AND ELECTRIC ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2023/195501
Kind Code:
A1
Abstract:
The present invention improves the power efficiency of a device equipped with an electric motor. A vibration test device according to one embodiment of the present invention is provided with a vibration table on which an object to be excited is attached, an electric actuator that vibrates the vibration table in a predetermined direction, and a controller that controls the electric actuator. The electric actuator includes an electric motor that can switch between forward rotation and reverse rotation, and a drive device that is supplied with electric power from a power source and that is controlled by the controller to supply the electric motor with driving electric power that excites the vibration table at the desired amplitude and frequency. The drive device includes a power source regeneration converter that, when the vibration table is excited at the desired amplitude and frequency, causes electric power not consumed by acceleration of the electric motor, out of the electric power generated from the electric motor, to be regenerated in the power source.
