Title:
電動アクチュエータ
Document Type and Number:
Japanese Patent JP7155767
Kind Code:
B2
Abstract:
An electric actuator includes: a motor unit having a motor shaft extending in an axial direction; a deceleration mechanism that is coupled to the motor shaft; an output unit having an output shaft to which rotation of the motor shaft is transmitted via the deceleration mechanism; and a control unit that drives the motor unit based on an output-shaft rotating command which is input from a host device. The control unit includes a motor rotational-angle determination unit that determines a rotational angle of the motor shaft based on the output-shaft rotating command, the rotational angle being necessary for rotating the output shaft from a rotation starting position to a rotation ending position, and a motor driving unit that rotates the motor shaft by the rotational angle determined by the motor rotational-angle determination unit.
