持するブラケット８よりなっている。Conventional Structure and Requirements Generally speaking, this type of step motor has a permanent magnet 1.0 as shown in FIGS. 1 and 2. It consists of a rotor 3 whose main element is a rotor core 2, and a stator 4 provided so as to surround the rotor 3. The stator 4 includes a rectangular stator core with a coil 6 wound around each pole, and the stator core 6.
It consists of a molded resin 7 that envelops the shaft 3, and a bracket 8 that supports one side of the shaft 3.
ところで前記ステータコア６は方形でありその角部は円

など悪影響を及ぼす原因となる。By the way, the stator core 6 is rectangular, and its corner portions are circular arcs, and 1) IJ molded resin wraps around one portion of the stator core 6, and the resin 7 is placed on top of the corner portions. ing. Therefore, the molded resin 7 at the corner of the stator 4
Since the bonding force with the stator core 6 is weak, the strength against external force is weak, and there is a risk that the resin 7 may be chipped or cracked if the motor is dropped. Also, the resin piece is the stator 4.
If there are gears around the motor, it may become stuck and cause adverse effects.
発明の目的

することを目的とするものである。Purpose of the Invention The present invention takes into consideration the above-mentioned problems, and improves the strength of the molded resin of the stator corner against external forces, and even if the gar corner is broken,
The object of the present invention is to provide a step motor in which resin pieces do not fall off from the stator.

タからの樹脂片の脱落を防ぐものである。Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a notch surrounding the motor mounting hole at the corner of the stator core, and molded resin is inserted into the cutout, thereby increasing the strength of the molded resin at the stator corner. Even if the stator is flipped or the corners are accidentally damaged, the resin surrounding the motor mounting screws prevents the resin pieces from falling off the stator.

Notches 98 to 9d surrounding 10d are provided, and the molded resin 12 is inserted into the cutouts 98 to 9d. Further, reference numeral 11 indicates mounting screws inserted into the motor mounting holes 1oΔ to 10C1.

樹脂片の脱落を防ぐ。According to this configuration, the bonding force between the molded resin 12 at the corners of the stator 4 and the stator core 1o is repelled, and the bowing strength against external forces is repelled.Also, even if the corners are bent, the resin 12 will remain in the motor mounting holes 101 to 10d. By surrounding the surrounding area, the mounting screws 11 can be inserted into the motor mounting holes 10 &~10d.
When the stator is inserted, the resin pieces are prevented from falling off from the stator as shown in Fig. 4.
