On the other hand, when the silicon steel sheet is processed and formed, the whole body of the silicon steel sheet is not deformed due to the processing of the rotor groove, and the forming rate of the silicon steel sheet is ensured.
Second, this scheme can increase the efficiency of air heat conduction at the motor during operation through adopting the circular shape rotor groove, makes the steam that gives off can follow the rotor inslot as much as possible and effluvium to as early as possible let steam laminating rotor inslot surface, so that the heat gives off speed faster, effectively guarantees the stable effect of motor in work.
Thirdly, this scheme is when bonding closed assembly silicon steel sheet, take place the position of rotatory every silicon steel sheet of carding through the backup pad, so that insert the round hole pole in the rotor groove, at this moment because the round hole pole portion diameter of leading the contact rotor groove is less, so that the process that the round hole pole inserted the rotor groove is more simple, insert the picture peg in the wire casing simultaneously, come every silicon steel sheet to carry out spacingly one by one, make the appearance of every silicon steel sheet form unified shape gradually, so that come the closed assembly to the silicon steel sheet, avoid being filled the rotor groove by required glue that bonds each other simultaneously, form the jam in rotor groove.
Fourth, this scheme is when round hole pole and picture peg are fixed a position, and insert the rotor inslot earlier through round hole pole lead, come to carry out earlier one step's location to the silicon steel sheet to it is better smooth and easy at the in-process that the picture peg got into the wire casing, guarantees the closed assembly efficiency of silicon steel sheet.
Fifthly, the heater is arranged on the round hole rod, so that the round hole rod can be more smoothly taken out in the process of taking the rotor groove out, redundant glue around the rotor groove is melted when the round hole rod is taken out, the glue solution is taken away along with the round hole rod, and the situation that the rotor groove is blocked and the like is avoided.
