High-precision permanent magnet servo motor rotor punching sheet

The invention discloses a high-precision permanent magnet servo motor rotor punching sheet, which comprises a rotor punching sheet body. Permanent magnet slots are arranged around the inner cavity ofthe rotor punching sheet body. Rotor slots are arranged on the inner and outer sides of the permanent magnet slots in the inner cavity of the rotor punching sheet body. Magnetic isolation slots are arranged on one side of the permanent magnet slots in the inner cavity of the rotor punching sheet body. Magnetic isolation bridges are arranged between the magnetic isolation slots and the permanent magnet slots. Through the setting and cooperation of the rotor punching sheet body, the permanent magnet slots, the rotor slots, the magnetic isolation slots, the magnetic isolation bridges and a rotating shaft, the advantages of good speed regulation performance and high precision are achieved, the problem that the existing permanent magnet servo motor rotor punching sheet has poor speed regulationperformance and low preci
