The invention relates to a rotor consisting of a magnet support part which is arranged on the peripheral surface of a rotating shaft and a magnet arranged on the peripheral surface of the magnet support part, and a rotor support structure for a slim step motor of a stator which is arranged at a certain interval from the peripheral surface of the magnet. In more detail, the invention relates to a supporting structure for supporting a rotor of a slim step motor, the structure is formed through steps of: making a stator consisting of a stator shell, a magnetic yoke, a rotating shaft support bearing and a terminal block by one-piece injection molding, and forming the rotor by a magnet support part pressed into the rotating shaft for fixing and a magnet arranged on the peripheral surface of the magnet support part, and then embedding the rotating shaft into a bore part of the rotating shaft support bearing, therefore the rotating shaft can be supported by one bearing.
Description
technical field [0001] The present invention relates to a thin step including a rotor composed of a magnet supporting part provided on the outer peripheral surface of a rotating shaft, a magnet provided on the outer peripheral surface of the magnet supporting part, and a stator provided at a certain distance from the outer peripheral surface of the magnet. The structure for supporting the above-mentioned rotor of a motor, in more detail, relates to the rotor supporting structure of a thin stepping motor as follows: In a thin stepping motor, a stator case, a yoke, a rotating shaft support bearing, and a terminal block are constituted The stator is integrally injection-molded, and the rotor is composed of a fixed magnet support part press-fitted into the above-mentioned rotating shaft and a magnet provided on the outer peripheral surface of the above-mentioned magnet supporting part, so that the above-mentioned rotating shaft is fitted into the inner diameter of the above-mention...
