A method of manufacturing a stator for an electromagnetic device, comprising a movable iron piece disposed on the other end face side of the electromagnet, and a permanent magnet is combined with the electromagnet, and the electromagnet is energized to cancel the output field by the permanent magnet at the time of control. .

ていたものである。At the time of trapping, the two yokes 1, 1. In the past, the permanent magnets 2 and 2 were each molded as separate members, and these were attached together using adhesive or the like as shown in Fig. 1.
If this is the case, the dimensional accuracy of the yokes 1, 1 and the permanent magnets 2 must be strictly checked during molding, otherwise the yokes 1, 1 and the permanent magnets 2 will not be properly attached or the yokes 1, 1. Since the permanent magnet 2 and the permanent magnet 2 are separate parts, the number of parts and the number of assembly steps increase, resulting in an increase in cost.
本発明は上記の如き従来技術の欠点に鑑みて成されたも
のであり、以下本発明について第２図及び第３図に基づ
いて説明する。The present invention has been made in view of the drawbacks of the prior art as described above, and the present invention will be explained below with reference to FIGS. 2 and 3.

々本発明の説明図である。As is clear from the above explanation, since the yoke and the permanent magnet are integrally molded in the present invention, there is no need to use the yoke and the permanent magnet as separate parts as in the past, and therefore the number of parts and assembly man-hours can be reduced. In addition, there is no gap between the yoke and the permanent magnet as in the conventional case. 2 and 3 are explanatory diagrams of the present invention, respectively.
