How it Works

1. 1. As an electric motor spins a flywheel, the torque generated is used to provide attitude stabilization about the axis the motor is mounted on.
2. 2. The QTA141 Micro Reaction Torque Sensor is mounted between a brushless DC motor and the wall of the satellite.
3. 3. As the electric motor spins the flywheel up to the commanded rotational velocity, the resulting torque is reported by the QTA141 Torque Sensor.
4. 4. The torque generated is used to provide attitude stabilization about the axis the motor is mounted on.
5. 5. The measured torque is then displayed and recorded with the USB220 via FUTEK’s SENSIT™ software.
