Inertial Actuator
Reaction flywheel is a torque actuator unit for satellite attitude control system. SAST has developed several series of reaction flywheel with mechanical and electrical integrated structure, digital signal I/O. Great moment reaction flywheel is featured with high wheel momentum control precision and optimal speed zero-crossing.
