Embodiment Construction
[0066] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0067] In a preferred embodiment, refer to Figure 1 to Figure 3 , The brushless DC motor rotor positioning method of this embodiment is applied to the brushless DC motor, the brushless DC motor includes A phase, B phase and C phase, and the A phase, B phase and C phase are separated by 120°. The brushless DC motor has the saturation effect of the stator core, which leads to a certain correspondence between the inductance of the motor winding and the position of the rotor. Therefore, the initial position of the rotor can be obtained indirectly by detecting the inductance of the stator winding. When a short-term voltage detection pulse with the same pulse width is applied to the stator winding, the rising speed of the cu...
