Description

technical field [0001] The invention relates to a silicon steel sheet processing device for permanent magnet synchronous motor production and a processing method thereof. Background technique [0002] The permanent magnet synchronous motor is a synchronous motor that is excited by a permanent magnet to generate a synchronous rotating magnetic field. The permanent magnet acts as a rotor to generate a rotating magnetic field. The three-phase stator winding reacts through the armature under the action of the rotating magnetic field to induce a three-phase symmetrical current. At this time, the kinetic energy of the rotor is converted For electric energy, the permanent magnet synchronous motor is used as a generator; in addition, when the three-phase symmetrical current is passed into one side of the stator, since the three-phase stators differ in space by 120 degrees, the three-phase stator current generates a rotating magnetic field in space, and the rotor in In the rotating m...

Problems solved by technology

Existing silicon steel sheets are generally formed by stamping, so it is necessary to make corresponding molds when manufacturing silicon steel sheets of different specifications and shapes, which not only causes waste of molds, but also cannot manufacture high-precision silicon steel sheets to meet the shapes of different permanent magnets and distribution requirements
