ONE Reaction Sphere can achieve same function in 1/3 volume, cost, weight and, power consumption. This is a TRL7 Reaction Sphere for CubeSats ranging from 1.5U, 2U, 3U, to 6U. In 2021, we are going to launch a verification flight and push it to TRL9. This motor functioning like a Single-Gimbal Control Moment Gyro in terms of rotational dynamics; and actuated by spherical motor technology. With this device, you can control the orientation of your CubeSat like 3 or 4 traditional single-axis reaction wheel did. However, the weight, size, and power consumption is lower.
