程を径で製作される。A rotor shown in FIG. 3 is used in the servo motor. In the figure, 1 is a shaft of a servo motor with one end serving as an output shaft end, and 2 is a rotor core that has a magnet 4 on the outer periphery of a core body 3 and is fitted onto the shaft 2. Therefore, the rotor is manufactured in diameter by first shrink-fitting the core body 3 onto the shaft l, then fitting and bonding the unmagnetized magnets 4 to the core body 3, and then magnetizing the magnets 4. Ru.

。By the way, the rotor with the conventional structure requires special equipment and jigs such as shrink fitting equipment, which requires a large amount of manufacturing equipment costs, and also requires the magnet 4 to be attached to the core body 3 to which the long shaft 1 is fitted. There were problems such as the gluing and magnetization work required for installation, which became difficult and required a lot of work time.

る。C action] In order to fit with the tapers, it is sufficient to press the shaft and the taper portion of the rotor core with screws, etc., eliminating the need for a shrink fitting device etc. when fitting the six-pronged shaft and the rotor core. Since no heating is required, a magnet can be attached and magnetized to the core body in advance. Therefore, bonding work and fF magnetic work are easy.
第１図はこの発明の実施例を示すもので、第３図と共通
あるいは同一の部分は同じ符号で示す。FIG. 1 shows an embodiment of the invention, and parts common or identical to those in FIG. 3 are designated by the same reference numerals.

としてなるナツトである。In FIG. 1, the fitting portions 1a and 3a of the shaft 1 and the core body 3 that fit into each other are respectively machined into a tapered shape and formed so as to form a conical fit. Further, an external thread 1b is formed on the outer circumferential portion of the shaft 1 connected to the tapered small diameter side. Reference numeral 5 designates a nut which is threadedly engaged with the male screw 1b, one end surface of which abuts against the end surface of the core body 3, and serves as a means for preventing the rotor core 2 from being removed and rotating.

合部１ａに嵌合わされ、ナツト５がおねじ１ｂにねじ込
まれる。In the above-mentioned configuration, the rotor first has a magnet 4 fitted and bonded to the machined iron core body 3, and the magnet 4 is magnetized. This adhesion and magnetization work is easy to handle because the shaft 1 is not attached to the rotor core 2, which is different from the conventional work.Next, the fitting portion 3a of the core body 3 and the nut 5 is screwed into the male thread 1b.
このナフト５の締込みによって嵌合部１ａと３８とが圧
着されて、回転子鉄心２が軸１に嵌着され、完成する。By tightening this napht 5, the fitting portions 1a and 38 are crimped, and the rotor core 2 is fitted onto the shaft 1, completing the process.
上述の如く回転子は焼嵌め等の専用の装置を必要とせず
、又容易な作業でもって製作され、さらに軸１に焼嵌め
による曲りの発生する心配がなく高い品質の回転子が得
られる。As mentioned above, the rotor does not require any special equipment such as shrink fitting, and can be easily manufactured.Furthermore, there is no fear that the shaft 1 will be bent due to shrink fitting, and a high quality rotor can be obtained.

止めできる利点を有する。Fig. 2 shows a modification of the embodiment shown in Fig. 1, which differs from the above embodiment in that key grooves are formed in the fitting part 1a of the shaft 1 and the fitting part 3a of the core body 3, and the key 6 was provided. In this modification, the same effects as in the above-mentioned embodiment can be obtained, and there is also an advantage that rotation can be prevented more strongly (and more reliably) between the shaft 1 and the rotor core 2.
