About
The Solar Array Drive Mechanism, Type 3, is an electromechanical device specifically engineered for spacecraft applications. Its primary purpose is to precisely rotate solar array wings at a specified rate, ensuring optimal sun exposure for power generation. Beyond mechanical rotation, it facilitates the electrical power transmission for control and telemetry signals, and it is capable of shaping and generating signals related to the output shaft rotation angle. This mechanism was first released in 1995 and boasts a guaranteed service life of 7 years. It has a flight qualification, with a brief history of flight on the Glonass-M satellites. The manufacturer offers the possibility to adapt the product to customer requirements, indicating flexibility in its design and integration. It operates in a continuous rotation regime.
