Title:
ELECTRIC LINEAR MOTION ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2017/199828
Kind Code:
A1
Abstract:
Provided is a space-saving high-torque electric linear motion actuator having a simple structure and reduced costs. This electric linear actuator (1) comprises: an electric motor (2); a linear-motion mechanism (3) which converts the rotary motion of the electric motor (2) into the linear motion of a linear-motion unit through a rotary input-output shaft (5); and a housing (4) which holds the linear-motion mechanism (3). The electric motor (2) comprises a stator (7) and a rotor (8) which are arranged such that the direction of the magnetic pole generating the interlinkage magnetic flux contributing to torque is parallel to the rotary shaft of the electric motor (2). The stator (7) is disposed by being coupled to the axial end surface of the housing (4). The rotor (8) is disposed in axially spaced relation to the torque generation surface of the stator (7), and is fixed to the rotary input-output shaft (5) of the linear-motion mechanism (3).
