Embodiment Construction

[0040] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as Figure 8 As shown, the most common structure of the traditional armature piece is the upper and lower winding slots with the same width, and the copper wires 3 can be staggered around, but when the rotor rotates at a high speed, such as 15000r / min-30000r / min, the operating environment temperature is also relatively high High, the copper wire 3 is easy to come out due to centrifugal force. The gap between the rotor and the stator of the motor is generally less than 0.5mm. If the copper wire of the rotor is slightly loose, it will rub against the stator, cause a short circuit, and damage the electromagnetic switch and the rotor and stator. Car wiring may be damaged.

[0042] Such as Figure 9 As shown in Fig. 1, another common upper narrow and lower wide structure of the traditional armature sheet windi...

Abstract

The invention discloses a high-rotational speed rotor for a vehicle starter and a manufacturing method of the high-rotational speed rotor. The high-rotational speed rotor comprises an armature shaft, an armature assembly and a commutator, wherein the armature assembly and the commutator are sequentially arranged at a middle part of the armature shaft, the armature assembly is formed by laminating a plurality of armature sheets, heat dissipation holes are annularly and uniformly formed in middle parts of the armature sheet, copper wires are wound around winding grooves by four layers in a staggered way, the copper wires are closed in the winding grooves by closed parts of the armature sheets, end parts of the armature sheets are protruded and then rolled to form sealing parts, the copper wires are limited in the winding grooves by the sealing parts, U-shaped grooves are formed in the outer circumference of the commutator and are equal in numbers of the winding grooves, initial ends and stop ends of the copper wires are laminated in the U-shaped grooves, and gaps among the copper wires and among the copper wires and the winding grooves are all filled with solidified 8411 solvent-free epoxy resin paint. The high-rotational speed rotor is firm and reliable in structure, the copper wires are prevented from being deformed and loosen even thrown away to cause the motor to be circuit-shorted when a vehicle starter motor is used in a high-temperature state, and the service lifetime of the motor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of starters, and in particular relates to a high-speed rotor for an automobile starter and a manufacturing method thereof. Background technique [0002] The car starter is a valuable part of the car. The car starting system converts the electric energy stored in the battery into mechanical energy. To realize this conversion, the starter must be used. The function of the starter is to generate power from the DC motor, and drive the crankshaft of the engine to rotate through the transmission mechanism, so as to realize the starting of the engine. The utility model patent 201520218047.5 of Dicks Auto Electric Shanghai Co., Ltd. has disclosed the structure of the rotor of the automobile starter. The copper wire winding method disclosed in this patent "the rotor is installed with multiple installation slots along the axial direction, and is wound sequentially on the installation slots" represents a typical tradi...
