C-B, U-V-W correspond to B-A-C or C-B-A, now, the magnetizing mistake and antiport of three-phase motor with permanent magnets.
In order to examine the wiring of three-phase motor with permanent magnets whether correct, by detecting the steering of motor in correlation technique, so as to
Judge whether A, B, C three-phase coil of stator correspond with external three-phase lead-out wire U, V, W to be connected.
The presence shortcoming of above-mentioned check system is, correlation technique be only capable of detecting motor steering whether mistake, so as to and
When correct the mode of connection for causing to turn to mistake, it is still, not corresponding with U phase lead-out wires connected in the event of A phase coils, and A phases
When coil, B phase coils and C phase coils sequentially correspond to wrong be connected, due to three-phase motor with permanent magnets Positive work, correlation technique can not
Detected, can only be found in the follow-up process that magnetizes, this will cause three-phase motor with permanent magnets complete machine to be scrapped, and cause huge damage

Number it is current signal, now, as shown in figure 11, predetermined threshold value can be predetermined current waveform（1）Peak value or integrated value, telecommunications
Number current waveform（2）Peak value or integrated value be less than predetermined current waveform（1）Peak value or integrated value, it is fixed that processor 30 judges
The three-phase lead-out wire distribution of son 40 is correct.In addition, in another embodiment of the present invention, the stator 40 of three-phase motor with permanent magnets
The three-phase coil distribution mistake of three-phase lead-out wire and stator 40, and the detection signal that processor 30 obtains is to detect the electricity of device 20
Signal, the electric signal are current signal, and now, as shown in figure 11, predetermined threshold value can be predetermined current waveform（1）Peak value or
Integrated value, the current waveform of electric signal（3）Peak value or integrated value be less than predetermined current waveform（1）Peak value or integrated value, place
Reason device 30 judges the three-phase lead-out wire distribution mistake of stator 40.
If it should be noted that during the three-phase lead-out wire of stator 40 and the three-phase coil distribution of stator 40 not
Carry out the detection of the corresponding relation of U-V-W three-phases lead-out wire and A-B-C three-phase coils, and the inspection without misalignment angle a
Survey, then when occurring wrong during the three-phase lead-out wire of stator 40 and the three-phase coil distribution of stator 40, when magnetizing,
The orientation angle of rotor can be placed still according to defined angle during correct magnetize.After electric current is passed through, formed in stator coil
Stator field direction can not be corresponding with the direction of permanent magnet in rotor, most cause magnetizing to fail at last, rotor and correlation
