Tips: stepper motor linear actuator in aviation industry
In the aeronautical dynamic system, the regulating valve is one of the most important flow regulating devices. The realization of motor propulsive force change and accuracy control largely depends on the characteristics of regulating valve, which requires a very precise proportion of the change of flow and the stroke of the stepping linear motor.
Now there is a new type of regulating valve which combines the stepper motor linear actuator and valve body. The main structure of the regulating valve is a stepper motor linear actuator, a valve core, a seat and a return spring. The valve core and the active cell of the stepper motor are connected with each other in structure. Due to the linear motion of the active cell, the valve core connected should also have linear motion. The valve can adjust the circulation area and the aperture, which forms the change of the flow, so that the flow can be controlled. If the throttle surface of the valve core is made into a para-curve, then the flow and stroke will have linear relation. Therefore, the stepper motor linear actuator with high reliability, high positioning precision and high performance has a very good application prospect in the aviation industry.
