Abstract: A rotor of the rotary electric machine comprising a ring, a plurality of magnetic pole portions, a plurality of slots and a plurality of magnets is provided. Each magnetic pole portion comprises two magnetic portions with an angle (C) between 20° ˜90°. The slots are configured between the magnetic pole portions to hold the magnets. Therefore, the magnetic field of the rotor is concentrated and the iron loss of the rotor is decreased.

Abstract: The present invention provides a cable fixture, where a hole with a varying inner diameter is disposed on a body, the body is used as a connection site for engaging the cable fixture with an external mechanical device, and the hole is used for a line to pass through so that after the inner diameter of the hole is reduced, the line passing through the hole is tightened, so as to achieve an effect of positioning the line.

Abstract: A rigid beam of portal frame type platform, including a hollow body section with a substantially rectangular cross section. The body section linearly extends by a predetermined length. At least one diaphragm section is disposed on the body section. Two sides of the diaphragm section are connected with two lengthwise sidewalls of the body section as seen in cross section to bridge the diaphragm section between the sidewalls. The diaphragm section and the length of the rectangular cross section contain a predetermined angle. Two protruding rails are disposed on outer face of one of the lengthwise sidewalls of the body section in parallel to each other as seen in cross section. The protruding rails extend along a length of the body section. A side seat protrudes from outer face of the other lengthwise sidewall as seen in cross section. The side seat extends along the length of the body section.

Abstract: Ball screw nut is composed of an inner threaded nipple and an outer housing. The nipple is constructed with a hollow hard tubular metallic material to ensure the strength of the structure; while the outer housing where requires less strength is formed of a plastic material by ejection mold process so as to reduce the production cost and simplify the fabrication process. The nipple and the housing are conjoined together by screw engagement.

Abstract: The bearing bush employed is divided into a main and a sub bearing bushes which are removable when filling the bearing balls into the bearing grooves so as to facilitate assembly work, moreover, weakening of preload on the preloaded ring can be compensated by adjusting the thickness of the preloaded ring by means of grinding.
