Project in collaboration with CSEM
Project description
A reaction sphere is proposed as a potential alternative to traditional Attitude and Orbit Control System (AOCS) actuators based on reaction wheels or control moment gyroscopes. The reaction sphere is a magnetic-bearing spherical actuator consisting of an 8-pole permanent-magnet spherical rotor that can be accelerated about any axis by a 20-pole stator with air-core electromagnets. A research prototype equipped with dedicated power electronics is manufactured to validate force and torque analytical models.
