Example Embodiment
[0111] In other embodiments of the present invention, the three-phase stator current I obtained in the above embodiment s_abc , three-phase stator voltage U s_abc Specific implementations include:
[0112] Obtain the output value I of the current sensor that matches the rated current of the motor s_abc ;
[0113] Get the output value U of the voltage sensor that matches the rated voltage of the motor s_abc .
[0114] The above current sensor and voltage sensor ensure that I s_abc and U s_abc Has high accuracy.
[0115] In addition, the stator voltage can also be obtained by means of voltage reconstruction.
[0116] In other embodiments of the present invention, specific implementations for determining whether the motor is in a steady state in steps S100 and S300 of the above embodiment include:
[0117] Calculate the total change Δω of the rotor speed of the motor within the preset time interval ΔT r ;
[0118] Judging Δω r Whether it is within the preset range, if ...
