接着剤を用いて接着固定していた。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the treatment of rotor windings of star-connected micromotors. The rotor of a conventional star-connected micromotor, e.g.
To explain the polar motor with reference to FIGS. 1a and 1b, the connecting portion 4' of the windings 1, 2, and 3 of each pole twists the ends 1a, 2a, and 3a of each winding 1, 2, and 3, The twisted portion was attached by hand and fixed at an appropriate position on the rotor 5, for example, at the adhesive portion 6 between the windings 1 and 2 using an adhesive.

This causes problems such as the build-up of the adhesive hitting the stator case (not shown), and furthermore, the organic gas generated from the adhesive causes chemical effects on the brushes and commutator, resulting in poor electrical conductivity. was.

タにハンダ付け等により接続されている。 The present invention aims to fix the connection parts of the windings by eliminating the use of adhesives that cause such drawbacks, and examples thereof will be described below with reference to FIGS. 2a and 2b. The connecting portion 4 of the pole windings 1, 2, and 3 is made by twisting each winding 1, 2, and 3, and soldering the base portion 4b, leaving the tip portion 4a extended by a predetermined length. Then, in the gap between the radially extending umbrella-shaped portion 7a at the tip of the rotor core 7 and the winding 1 which is wound and overhangs to the umbrella-shaped portion 7a, the tip of the connecting portion 4 is inserted as shown by the broken line in FIG. 2b. The connecting portion 4 is fixed to the rotor 5 by wrapping and sandwiching the connecting portion 4a. The other ends 1b, 2b, and 3b of the windings are connected to the commutator by soldering or the like.
従つて接続部４はロータコア７の先端部の傘状

化もない。 Therefore, the connection part 4 is held by simply inserting it between the umbrella-shaped part 7a at the tip of the rotor core 7 and the winding 1 that extends up to the umbrella-shaped part 7a. The umbrella-shaped part 7 of the rotor core 7 is also off.
It is safe because it does not come out against the centrifugal force caused by the rotation of the rotor 5, and since no adhesive is used, there is no deterioration of the brushes and commutator due to organic gas.

The present invention provides a micromotor rotor that has various effects.
なお接続部４の導通のさせ方はハンダ付けによ
らず絶縁被覆をはがして捩るだけでも良い。 The connecting portion 4 may be made conductive by simply peeling off the insulation coating and twisting the connecting portion 4 instead of soldering.
