Embodiment 1
[0061] This embodiment is an outer rotor motor, and its specific structure is as attached Figure 4 attached Figure 5 And attached Figure 6 As shown, the number of "permanent magnet salient pole pairs" of the rotor in this embodiment is twice the number of "excitation salient pole pairs" of the stator, that is, M=2N, where M is twelve, N is six, and k is 2. An example is to solve the motor starting by biasing the two sets of rotor "permanent magnet salient pole pairs" structure.
[0062] Figure 4 It is a cross-sectional view of the structure of Embodiment 1. (For the convenience of explanation, the equilibrium state generated by the α angle is ignored, and the figure is the actual state for analysis). The stator is composed of a stator seat 206 and six "excitation salient pole pairs", and six "excitation pole pairs" The “salient pole pairs” take the rotation axis 208 as the axis of symmetry, and are arranged radially symmetrically on the periphery of the stator seat 206,...
Embodiment 2
[0068] The structure of this embodiment is as attached Figure 7-9 shown. The structure of this embodiment is basically the same as that of Embodiment 1, the only difference lies in the winding method and setting position of the excitation coils of the stator "excitation salient pole pairs". In this embodiment, the excitation coils are divided into two groups and wound in series on the salient poles of the iron core, so that the axial length of the motor can be shortened to meet special needs.
[0069] The asymmetric arrangement of the "permanent magnet salient pole pairs" of the rotor in this embodiment, the self-locking mechanism when the motor is powered off, the motor start-up, the operation process, and the automatic air cooling of the motor are the same as those in the first embodiment, and will not be repeated here.
Embodiment 3
[0071] This embodiment is an external rotor motor, the number M of rotor "salient pole pairs" is twice the number N of stator "salient pole pairs", that is, M is 10, N is 5, and k is 2.
[0072] In this embodiment, a structural form of biasing a stator excitation salient pole pair can be adopted to solve the problem of starting the motor. Figure 10 The structural section of this kind of bias mode motor. In the figure, the relative position of the stator and the rotor is an initial state when the motor is de-energized, that is, the self-locking state, and the four excitation salient pole pairs A, C, D, E are respectively facing the permanent magnet salient pole pair I on the rotor. , Ⅴ, Ⅶ, Ⅸ, and there is an offset α-degree central angle between the salient pole radial centerline of stator excitation salient pole pair B and the salient pole radial centerline of rotor permanent magnet salient pole pair Ⅲ. Another initial state in the case of power failure of the motor in this ...
