Abstract

The invention discloses a die assembly used for manufacturing a motor, a manufacturing method for a stator punching sheet, a manufacturing method for a stator punching sheet, the motor and a compressor. The die assembly comprises a first die, a second die and a third die, wherein the first die adopts a columnar structure with a hollow interior, and comprises a punching inner surface and a punching outer surface; the second die is used for punching an annular punching sheet to form a first punching sheet groove; the annular punching sheet with the first punching sheet groove is applicable to one kind of motors; the cross section shape of the third die is different from that of the second die; the third die is used for punching an annular punching sheet to form a second punching sheet groove; and the annular punching sheet with the second punching sheet groove is applicable to another kind of motors. According to the die assembly used for manufacturing the motor disclosed by the invention, the first die can be shared in punching the outer contours and inner contours of stator punching sheets or rotor punching sheets of different motors, so that production efficiency is improved and production cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular, to a mold and processing method for stator stamping and rotor stamping, a motor and a compressor. Background technique [0002] Frequency conversion motors are used in refrigerator compressors.
