| titleOfInvention | A method of controlling motor speed reduction |
| abstract | The invention relates to the technical field of air compressor control systems, in particular to a method for controlling motor deceleration, comprising: determining the maximum operating voltage Vlimt of the busbar according to the hardware characteristics of the controller, and taking the maximum operating voltage Vlimt as the voltage The target bus voltage V limt of the closed-loop system; the actual bus voltage obtained in real time is used as the feedback of the voltage closed-loop system; when the deceleration command is received, the voltage closed-loop system intervenes to work, and the target bus voltage V limt and the actual bus voltage are input In the voltage closed-loop system, the voltage closed-loop system outputs the Q-axis reference current or the output deceleration frequency to control the motor deceleration; during the motor deceleration process, the D-axis current and the Q-axis current are limited by the power device; Step S3 is executed, Until the motor reaches the target rotation speed; under the condition of protecting hardware safety, the invention makes the motor decelerate at the maximum deceleration, shortens the deceleration time of the motor, and improves the life of the air compressor bearing. |
