Embodiment Construction
[0072] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0073] Such as figure 1 Shown, the method of the present invention realizes as follows:
[0074] The first step is to use the oscilloscope to collect the waveforms of the three-phase electromotive force of the permanent magnet synchronous motor at different speeds, and derive the discrete data of the three-phase electromotive force of the permanent magnet synchronous motor that changes with time in the oscilloscope, convert the time into a phase, and extract a Periodic three-phase opposite electromotive force.
[0075] The second step is to unitize the three-phase electromotive force of the permanent magnet synchronous motor at different speeds. When the unit back-electromotive force waveform does not change much in the full speed range of the motor, it only needs to process the three-phase electromotive force of one cycle at any speed.
