The utility model discloses a reduction motor control mechanism, which comprises a DC (Direct Current) motor, a speed reduction gear box and a terminal board, wherein an output shaft of the DC motor is in transmission connection with an input terminal of the speed reduction gear box, and the speed reduction gear box is provided with an output terminal for transmission connection with a load; a power input terminal electrically connected with a power wiring terminal of the DC motor, a Hall element which is close to the DC motor and determines the rotating speed, and a detection element for detecting the output terminal of the speed reduction gear box to rotate in place are arranged on the terminal board. According to the reduction motor control mechanism, the DC motor replaces the traditional stepper motor, and a displacement adjusting function is realized by closed-loop control. Compared with the control mechanism of the reduction stepper motor, the reduction motor control mechanism has a considerable power s
