Description

Technical Field

[0001] This utility model belongs to the field of internal grinding for punching, specifically a device for internal grinding of stator and rotor punching. Background Technology

[0002] The stator and rotor are important components of an electric motor, consisting of two parts: the stator and the rotor. The stator is the stationary part of the motor, on which a pair of DC-excited stationary main magnetic poles are mounted. The rotor is the rotating part inside the motor, also called the armature core, on which the armature windings are mounted. When energized, it generates an induced electromotive force, which acts as a rotating magnetic field. The stator and rotor are composed of several laminations. During the manufacturing process, the laminations need to be punched to facilitate the installation of magnetic poles. Multiple holes arranged in a ring array are required.

[0003] Since the smoothness of the laminations directly affects the efficiency of the motor, the stator and rotor laminations need to be deburred after the holes are punched. For the grinding of the holes, different punching specifications usually require grinding heads of different sizes, which is inconvenient to adapt to different punching specifications and increases the workload of replacement.
