After the motor is decelerated by the gear, it drives a pair of screw nuts. The motor rotation motion into linear motion, using the motor positive and negative rotation to complete the push rod action. Such as through a variety of levers, rocker or connecting rod and other mechanisms can complete rotation, shaking and other complex actions. The stroke can be increased or decreased by changing the lever lever arm length. Stroke control device.

Worm gear transmission form: the worm drive worm gear on the motor gear rotation, so that the worm gear in the small screw for axial movement, driven by the connecting plate limit rod corresponding axial movement, to the required travel, by adjusting the limit block pressure travel switch power off, the motor stops running (positive and negative control the same).

Gear transmission form: the motor drives the small lead screw installed in the inner tube through the reduction gear, and drives the axial running nut connected with it. When the set stroke is reached, the nut tentacles press the limit switch to disconnect the power supply, and the motor stops moving (the reverse is the same with it). Optional potentiometer, to display the push rod running stroke state, can also be equipped with an encoder, to achieve a few steps to walk the complete stroke (i.e. stop and go).

Design features novel and exquisite, small size, high precision, complete synchronization, good self-locking performance, health, direct motor drive, do not need pipeline air source, oil circuit, has been widely used in the production line, automobile, air window open, military, stage, textile, sewage treatment and other industry equipment.
