Motor stator manufacturing method and motor stator

Abstract

A motor stator manufacturing method and a motor stator are used for solving the problem that a circuit board is easy to incline when an existing motor stator is assembled, and the motor stator manufacturing method comprises the steps that a winding set is provided with a magnetic pole piece combined with an insulating piece, a coil is wound on the insulating piece, and the winding set is providedwith at least one axial through hole; the circuit board is axially opposite to the winding group; and the at least one guide connecting piece is arranged in the at least one axial through hole in a penetrating manner, the at least one guide connecting piece is provided with a first end and a second end, the second end is closer to the circuit board than the first end, the first end is combined with the coil in a welding manner, and the at least one guide connecting piece is connected with the circuit board only through the second end.

Description

technical field [0001] The invention relates to a method for manufacturing a motor part and the motor part, in particular to a method for manufacturing a motor stator and the motor stator. Background technique [0002] Please refer to figure 1 , which is an existing motor 9, the existing motor 9 has a base 91, the base 91 has a shaft tube 911, a bearing 92 is accommodated in the shaft tube 911, a stator 93 is located on The outer periphery of the shaft tube 911, the stator 93 has an insulating sleeve 931 and a circuit board 932 located below the insulating sleeve 931, there is a minimum distance h1 between the insulating sleeve 931 and the circuit board 932, the stator 93 is in the The bottom surface of the insulating sleeve 931 has a winding post 933, which is welded and combined with a coil 934 to form a welding height h2, and the winding post 933 penetrates the circuit board 932 and is welded and combined with the bottom surface of the circuit board 932, so that the The...

Problems solved by technology

However, since the winding post 933 is welded to the coil 934, it is located between the bottom surface of the insulating sleeve 931 and the circuit board 932, and the minimum distance h1 here is very small. Excessive tin liquid or unfamiliarity with the welding operation may cause the welding height h2 to be too large; or, when there are more than two winding posts 933, if soldering with tin liquid causes each winding post 933 If the soldering height h2 is inconsistent, it is easy to squeeze the solidified tin onto the circuit board 932 and cause the circuit board 932 to tilt. Therefore, in order to avoid the circuit board 932 from tilting, it is necessary to more carefully control the amount of tin used during soldering and action, resulting in the difficulty of welding operation and the difficulty of improving the efficiency
