[0041] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0042] The invention discloses a positionless speed-up method for an electrically excited double salient motor. The system structure of the electrically excited double salient motor is as follows: figure 1 As shown, it includes electric excitation doubly salient motor, three-phase full-bridge inverter, excitation power circuit, control circuit, sampling conditioning circuit, etc.
[0043] like Figure 5 Shown, the specific implementation steps of the present invention are as follows:
[0044] Step 1), before starting, when the motor is at rest, turn on the power tube of the excitation circuit to increase the excitation current to the rated value, and simultaneously detect the three-phase terminal voltage U during the increase of the excitation current A , U B , U C .
[0045] During the rising process of excitation current, the expression of t...
