The output performance of the stepper motor corresponds exactly to the input pulse, but the rotational speed and torque of its output are limited. The linear motor can save a certain transmission link, improve the transmission precision and dynamic response performance of the mechanism, but is difficult to control. The servo motor adopts closed-loop control, and has high output speed, high position accuracy, quick response and strong overload resistance.
Aiming at the development requirements of high reliability, low impact and detectability of the space connection unlocking mechanism, a point type separating mechanism is provided, and the electrically driven latch hook type connection unlocking mechanism can be used for separating the stages of a carrier rocket, separating a fairing, separating a payload and the like.
