Title:
AUTO BALANCER
Document Type and Number:
WIPO Patent Application WO/2023/145279
Kind Code:
A1
Abstract:
Provided is an auto balancer that is shorter in an axial direction of an axis of rotation than in the past. This auto balancer comprises a balance head which rotates integrally with a rotating body about an axis of rotation of the rotating body, and which includes an electric-powered balance correcting mechanism for correcting unbalance of the rotating body and a case that has a cylindrical outer circumferential surface parallel to the axis of rotation and that accommodates the balance correcting mechanism, a stator which is provided separately from the balance head, has a shape that follows a circumferential direction of the outer circumferential surface, spaced apart from the outer circumferential surface across a gap, and is electrically connected to a controller of the balance head, and a rotor unit which is provided in a position facing the stator on the outer circumferential surface, rotates integrally with the balance head, has a shape that follows the circumferential direction of the outer circumferential surface, and is electrically connected to the balance correcting mechanism, wherein wireless transmission is possible between the stator and a rotor.
