The traditional airborne electric mechanism is mostly controlled by mechanical switch, which seriously restricts the life and reliability of the system. This paper introduces a design method of a lightweight electric mechanism without a controller. The electric mechanism drives the motor directly by receiving the instructions of the control system, acts directly on the switch of the pipeline valve through the decelerator, breaks down the lock after reaching the specified position, and feeds back the current position signal. It is a high reliability, long life, compact structure, and widely used EMA product, which can adapt to all kinds of extreme environments required by the airborne equipment. And it has good maintainability.
