Title:
STATOR SUPPORT FRAME AND STATOR
Document Type and Number:
WIPO Patent Application WO/2020/238266
Kind Code:
A1
Abstract:
The present invention relates to a stator support frame and a stator. The stator support frame is applied in a large-diameter motor, and comprises: a stator shaft coaxially connectable to a fixed axle of a motor; a supporting assembly coaxially provided at the periphery of the stator shaft; a stator ring connectable to a stator iron core of the motor, wherein the stator ring comprises two or more curved stator ring sections continuously arranged in a circumferential direction thereof, and the two or more curved stator ring sections are coaxially provided at the periphery of the supporting assembly. In the stator support frame, a stator ring connectable to a stator iron core of a motor is divided into two or more stator ring sections arranged in a circumferential direction, such that the maximum outer size of the stator ring section can be controlled to be within transportation limits, thereby solving the problem in which transport of a stator support frame of a large-diameter motor is difficult.
