One Reaction Sphere can achieve the same function as 3 traditional reaction wheels do, but in nearly 1/3rd of the volume, cost, weight, and power consumption. Its max. angular momentum and max. torque can be customized for CubeSats ranging from 1.5U, 2U, 3U, to 6U. In terms of rotational dynamics, this motor functions like a single-gimbal Control Moment Gyro (CMG); but is actuated by a spherical motor. Moreover, this motor can act like 3 magnetorquers in X, Y, and Z axes when bias currents are applied. With this device, you can control the orientation of your CubeSat like 3 traditional single-axis reaction wheels and 3 magnetorquers do. However, the weight, size, and power consumption is lower.
