Problems solved by technology

For the armature slot, the straight slot structure is generally used now. However, when the armature wire is wrapped, the paper will overlap at the junction of the insulating paper. When the above straight slot structure is adopted, the armature wire and the armature slot will A gap greater than or equal to the width of two sheets of insulating paper is produced, which greatly reduces the slot fullness rate, thereby affecting the electrical performance of the motor

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Examples such as figure 2 , image 3 , Figure 4 Shown: the present invention relates to an armature used in a starter, comprising: a plurality of teeth 12; a plurality of armature slots 11 formed between adjacent teeth 12; For the armature wire 2 in the slot 11, a groove 11-1 with a groove depth of 0.2mm is provided in the middle of the two side walls of the armature groove 11, and the groove width d of the groove is larger than the groove width of other parts of the armature groove 11. h, the insulating paper 3 thickness that adopts in the present embodiment is 0.2mm, when installing as Figure 5 As shown, the overlapping insulating paper is placed in the slot, so that the gap between the insulating paper and the armature slot is hidden in the slot, thereby increasing the slot fullness rate and improving the motor per...

Abstract

The invention discloses an armature in a starter. The armature disclosed by the invention comprises multiple teeth and multiple armature slots formed among the adjacent teeth. In the armature disclosed by the invention, grooves are respectively formed on two side walls in the middle of the armature slots; the overlapped parts of insulation paper is installed in the grooves; and the depth of the grooves is 0.2-0.3mm, thereby reducing the gap between armature lines and the armature slots to the greatest extent. The armature disclosed by the invention enables the overlapped parts of the insulation paper to be installed in the grooves, thereby reducing the gap between the armature lines and the armature slots, enhancing the slot fullness and improving the performance of a motor. The new structure provided by the invention can be used for reducing the cross sections of the armature lines and lowering the cost.

Description

technical field [0001] The invention belongs to the modification of the structure of the internal parts of the starter, and in particular relates to an armature structure for the starter of an automobile. Background technique [0002] At present, the armature structure of most starter motors is as follows: figure 1 As shown: the armature includes a plurality of teeth; a plurality of armature slots formed between adjacent teeth; and armature wires wrapped in the armature slots by insulating paper. For the armature slot, the straight slot structure is generally used now. However, when the armature wire is wrapped, the paper will overlap at the junction of the insulating paper. When the above straight slot structure is adopted, the armature wire and the armature slot will A gap greater than or equal to the width of two sheets of insulating paper is produced, which greatly reduces the slot fullness rate, thereby affecting the electrical performance of the motor.
