The present invention discloses a compressor, a variable frequency motor, a stator punching sheet of the motor, and a machining method thereof. The stator punching sheet comprises a first axis of symmetry, and a second axis of symmetry. The first axis of symmetry and the second axis of symmetry are perpendicular to each other and divide the stator punching sheet into four identically shaped unit parts. Each unit part comprises an inner-ring contour line segment and an outer-ring contour line segment. The outer-ring contour line segment comprises a first half edge, a bevel edge and a second half edge, wherein the first half edge, the bevel edge and the second half edge are successively connected. The first half edge is perpendicular to the first axis of symmetry. The second half edge is perpendicular to the second axis of symmetry. A raised portion is arranged between the bevel edge and the second half edge. The stator punching sheet is provided with an installation hole. At least one part of the installation hole is arranged on the raised portion. According to the technical scheme of the stator punching sheet of the motor, based on the mutual cooperation of the first half edge, the bevel edge and the second half edge, molds can be staggered up and down in the misalignment manner during the machining process. Therefore, the excess material waste of raw materials during the machining process is reduced. The utilization rate of materials is improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a compressor, a variable frequency motor, a stator punch of the motor and a processing method thereof. Background technique [0002] Compressor is an important component in refrigeration equipment, and its performance directly affects the overall performance of refrigeration equipment. Taking the compressor used in the frequency conversion refrigerator as an example, the shape of the stator stamping plate of the frequency conversion motor is often designed as a quadrilateral structure. When the stator punching of this structure adopts the up-and-down staggered method to discharge the mold, the waste area at the junction of the three punching sheets is large, the material utilization rate is low, and the magnetic induction intensity at the periphery of the stator punching sheet is low. Contents of the invention [0003] The present invention aims to solve one of...
