Document Type and Number:
WIPO Patent Application WO/2018/139387
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electric linear actuator that can improve the instantaneous output of an electric motor and allows size and cost to be reduced. A control device (2) of this electric linear actuator includes: a motor driver (24) that controls power supplied to a coil (4b) of an electric motor (4); a power storage means (21) that is connected to a power source device (3) and the motor driver (24); an energization direction limiting means (20) which is disposed between the power source device (3) and the power storage means (21) and which allows current to pass only in the direction of supplying power from the power source device (3); and a step-up means (19) that steps up the voltage of the power source device (3) and outputs the stepped-up voltage to the power storage means (21).
