Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically relating to a multi-layer composite stamping mold for a self-bonding iron core of an axial flux motor. Background Technology

[0002] The stator core is a crucial component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the motor. In an asynchronous motor, the magnetic flux within the stator core is alternating, resulting in core losses. Core losses consist of two parts: hysteresis losses and eddy current losses.

[0003] As the silicon steel sheets used in motor cores are becoming thinner and thinner, the stamping time for a single core is getting longer and the efficiency is getting lower. Therefore, a multi-layer composite stamping die for self-bonding cores of axial flux motors is needed. Utility Model Content
