When the motor is energized, electromagnetic torque is generated and the double-sided brake is closed.
The rotor starts to rotate at 2850 revolutions per minute, and the speed and torque of the rotor are input to the planetary gear train gearbox through the coupling, and after decelerating through the large speed ratio of the gearbox, the output torque is transmitted to the transmission pipe through the runner. The rotation of the drive pipe thus realizes the lifting and lowering of the door or window.
The rotation of the transmission pipe drives the rotation of the yellow crown and the inner tooth sleeve, and the toothed nut is driven by the intermediate transmission gear, so that the toothed nut slides up and down the screw, and the toothed nut controls the opening and closing of the stroke switch through the bumper, so as to realize the control of the stroke. After the power is cut off, the double-sided brake brakes and the motor immediately stops running.
