The utility model discloses a cylinder magnetic steel structure including a sleeve, a magnetic steel body, a magnet vane and a rotating shaft, the outer contour of the magnetic steel body is cylindrical, the magnetic steel body is located in the sleeve, one end of the rotating shaft extends into the sleeve and is arranged opposite to the magnetic steel body, the magnet vane is located in the sleeve, and the magnet vane is located between the magnetic steel body and the rotating shaft. According to the utility model, through the above structure, the sleeve can be uniformly stressed, which is beneficial for designing and manufacturing a motor with a higher rotating speed; besides, the cylindrical magnetic steel can be magnetized after being assembled, demagnetization caused by thermal assembly does not need to be worried about, and the assembly process can be greatly simplified during non-magnetic assembly; in actual use, the magnetic field waveform of the rotor is good, the harmonic content is low, and the tem
