Title:

BRUSHLESS DIRECT DRIVE LINEAR SERVO ACTUATOR

Document Type and Number:

WIPO Patent Application WO/2020/259639

Kind Code:

A1

Abstract:

The present invention provides a brushless direct drive linear servo actuator, comprising: a stator, a mover and a housing, wherein the stator is a pair of armatures arranged in mirror symmetry at both sides of the mover, the housing integrally encapsulates the stator and forms a cavity for the mover at the mover, and the mover has an output end protruding out of the housing and is linearly movable along a direction of the output end. A displacement signal emitter is provided at a side of the mover, and a signal receiver is provided within a cover arranged outside the housing on said side for detecting a displacement signal emitted by the emitter of the mover. The actuator of the present invention is characterized by high reliability, high accuracy and low cost.
