Claims

[Claims for Utility Model Registration] 1. A shorting ring that short-circuits or opens a secondary circuit, consisting of a cylindrical portion and a pair of collars attached to both ends of the cylindrical portion, and the shorting ring inserted through the cylindrical portion. A shaft that slidably supports the shaft, an inner frame that is composed of an upper and lower frame and both side frames and that supports a pair of bearings that are slidably engaged with the outer peripheral surfaces of both sides of the cylindrical portion, and an upper frame of the inner frame. an outer frame composed of an upper frame that supports the inner frame at two points, a lower frame that supports the lower frame of the inner frame at one point, and both side frames; a lever having a middle portion fixed to the lower frame of the outer frame; and both ends of the lever. The first, attached to the
a second roller, a short-circuit crank configured to be rotatable and having a spiral groove that engages with the first roller; and the second roller.
A short-circuiting mechanism device for a wound motor, comprising a support member that rotatably supports a roller. - 2. The short-circuit mechanism device for a wound wire electric motor according to claim 1, wherein the lower frame of the inner frame is supported at one point by the lower frame of the outer frame via a pin. 3. The short-circuit mechanism device for a wound wire electric motor according to claim 1 or 2, wherein both sides of the inner and outer frames are rotatably supported by the respective upper frames via pins. .
