Example Embodiment
[0020] Such as figure 1 with figure 2 As shown, the present invention has a lamella rotor 1 and a stator 2. The inner diameter of the stator 2 is larger than the outer diameter of the lamella rotor 1, and the lamella rotor 1 is coaxially sleeved in the stator 2. A cylindrical magnetic flux collecting device 3 is coaxially sleeved inside the thin rotor 1, and the magnetic flux collecting device 3 is made of magnetic conductive material. The inner diameter of the sheet rotor 1 is larger than the outer diameter of the magnetic flux collecting device 3, and a radial air gap 15 is left between the magnetic flux collecting device 3 and the sheet rotor 1. The central axis of the magnetic flux collecting device 3 is the central axis of the motor.
[0021] The sheet rotor 1 adopts a 4-pole salient pole structure. The stator 2 is composed of 6 identical L-shaped stator core columns, and the 6 identical L-shaped stator core columns are evenly distributed along the circumferential directio...
