The invention discloses a high-efficiency and energy-saving control method for segmented decelerating shutdown of a direct current variable frequency motor for a circular weaving machine. The circular weaving machine comprises a main machine, a let-off system, a winding device, a rack and a direct current variable frequency motor controller, wherein the main machine comprises a direct current variable frequency motor, a driving system, a warp yarn separating mechanism and a weft inserting mechanism; a motor speed detecting device is matched with the direct current variable frequency motor controller to perform segmented control over shutdown speed of the main machine of the circular weaving machine; by adopting segmented decelerating shutdown control, decelerating time of the motor changes along with a set value in the segment with the decline of a speed value of the motor. The shutdown time is shortened; meanwhile, secondary tracking and positioning and control over tail speed for decelerating point control can be realized, and optimization control over decelerating shutdown is realized.
