Embodiment Construction
[0016] see figure 1 and figure 2 , in the axial direction, the axial bottom of the motor is a steel chassis 11, and the top surface of the steel chassis 11 is fixedly connected with an iron core yoke 5 in the middle, and the two are on the same axis line. A cross-shaped thin-plate rotor 1 and a rotor permanent magnet 3 are coaxially arranged directly above the core yoke 5 , and the rotor permanent magnet 3 is in the shape of a round pie, coaxially and fixedly connected to the top surface of the cross-shaped thin-plate rotor 1 . The outer diameter of the rotor permanent magnet 3 is smaller than that of the cross-shaped sheet rotor 1, and the two form a whole. The rotor permanent magnet 3 is axially magnetized, and the bottom end close to the cross-shaped sheet rotor 1 is an N pole, and the top end is an S pole.
[0017] The radial section of the cross-shaped thin-plate rotor 1 is cross-shaped and has a 4-pole salient-pole structure. An annular aluminum alloy ring 15 is tigh...
