本発明はスタータ等に用いるモータのボールコア構造に
関するもので、直巻用のボールコアのボールアングル小
のものを提供し、特性の向上を図ることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball core structure for a motor used in a starter or the like, and an object of the present invention is to provide a ball core for direct winding with a small ball angle and to improve its characteristics.

性に悪影響を与えているという欠点がある。Conventionally, when directly winding a field coil, the chip width of the ball core was increased to prevent the coil from falling off during winding, but this increased the ball angle, worsening rectification and adversely affecting characteristics. There are drawbacks.

ることを目的とする。In order to solve the above-mentioned drawbacks, the present invention makes a part of the chip of the ball core non-magnetic by insert molding a resin material, etc., and prevents the chip from falling off when the field coil is directly wound, while improving the characteristics of the motor. The ball angle, which affects commutation, is determined by the area occupied by the non-magnetic material. By setting the ball angle to the optimum ball angle for the motor, a ball core with a part of the chip made non-magnetic can be used for motors that use a direct winding field. The purpose is to improve characteristics and rectification.
以下本発明を図に示す実施例について説明する。The present invention will be described below with reference to embodiments shown in the drawings.

アングルθ２に設定する。1 to 3, a portion lb of the chip 1a of the ball core 1 made of a magnetic material is made non-magnetic by insert molding with a resin material or coated with resin, and when winding the field coil 2, While the tips la and lb prevent the windings from falling off, the ball angle that affects the characteristics and commutation of the scooter motor is set to the optimum ball angle θ2 for the motor.

きる。The ball core 1 in which a portion lb of the chip 1a is made non-magnetic can improve the characteristics and rectification of a series starter motor. Furthermore, by making a portion lb of the chip 1a of the ball core 1 non-magnetic, it is possible to set the optimum ball angle θ2 for the starter motor regardless of whether S#J3I falls off or the like.

A part of the chip 1a lb is formed using resin, and the ball angle is set to 02 = 68.5.
By setting (chip width L2 = 50 pieces), the output of the starter motor could be increased by 5%. However, the optimum value of the ball angle differs depending on the yoke diameter, armature diameter, stacking thickness, etc. of the morph part, and this result shows only one example.
