Description

Technical Field

[0001] The utility model relates to the field of stator core processing, in particular to a clamping tool for processing the stator core. Background Art

[0002] The iron core is the core component of the motor, which is used to increase the magnetic flux of the inductor coil to achieve the maximum conversion of electromagnetic power. It plays a pivotal role in the entire motor. During the production and processing of the existing annular iron core, it is necessary to remove the burrs on the edges and inside to improve the smoothness and processing quality.
