Title:
ELECTRIC LINEAR ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2018/008709
Kind Code:
A1
Abstract:
Provided is an electric linear actuator such that a reduction in installation space and a reduction in cost can be achieved. This electric linear actuator comprises an electric motor that is an axial gap motor which is provided with a stator (7) and a rotor which are arranged so that the direction of magnetic poles generating interlinkage magnetic flux contributing to torque becomes parallel to the rotation axis (L1) of the electric motor. Furthermore, a linear mechanism and the electric motor are arranged adjacent to each other on the same axis, which is the axis of the rotary input/output shaft of the linear mechanism. First and second coil terminals (53), (54) have extension portions (53a), (54b) extending towards the outer diameter in the radial direction of the rotation axis (L1), the extension portions (53a), (54a) being electrically connected to a control device through a wiring mechanism.
