Motor stator punching sheet laminating technology

Abstract

A motor stator punching laminating technology comprises the following steps: a, the same row of punching sheets manufactured by the same silicon steel strip are arranged into a plurality of parts under the control of a punching arrangement screen, and the punching sheets are automatically marked; b, according to the total height of a stator, the stator punching sheets are separated into an even number of parts, and the fewer the punching sheets in each part are, the straighter the axial lead of the stator is after completion; and c, when the punching sheets are laminated, the punching surfaces are always upward, each part is laminated after being rotated at a certain angle relative to the another adjacent part according to the mark direction compiled in advance, and the thicker side of the previous part is laminated on the thinner side of the next part to achieve complementation, so that the thickness is regulated to be uniform within the minimum height range as much as possible, and accordingly, the punching sheets are laminated to the height required by the stator in sequence. By adopting the motor stator punching lamination technology, the perpendicularity of the axial lead of the stator can be strictly controlled, and the mounting space between the rotor and the stator is controlled below 0.3mm, so that the motor efficiency is improved exponentially.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a process for lamination stacking of motor stators. Background technique [0002] The motor stator is the key part of the motor. It is made of multi-layer punched sheets. Because the stator punched sheet is very thin, but its shape is extremely complicated, the spacing of many holes and slots is only a few millimeters. It becomes a waste product in a ball; so at present, multi-station punching is used to make stator punching sheets, that is, a silicon steel belt is stepping intermittently on the punching machine, and a part of the hole is punched every step of the way, and a punching sheet needs to be moved six or seven times. Only one step or more can be completed. The width of the silicon steel belt only allows 2-3 rows of punches to be placed in a cross arrangement. The longitudinal position of each punch on the silicon steel belt is strictly positioned. Most of the silico...
