0.3 N·m·s Reaction Wheel

The reaction wheel serves as a key actuator within a satellite’s attitude control system. Its primary function is to counteract external disturbance torques acting on the satellite. When such disturbances occur, the reaction wheel responds to commands by either accelerating or decelerating. This action generates a reaction control torque, which effectively absorbs the angular momentum changes caused by the disturbances. By doing so, the reaction wheel plays a crucial role in maintaining the stable attitude of the satellite. A reaction wheel with a momentum capacity of 0.3 N·m·s is typically well-suited for satellite platforms weighing between 30 and 100 kg.
