Prototype of Micro Reaction Wheel for Cubesat

Tel-USat is a Cubesat 1U which is designed to capture the Earth surface photograph using serial camera. To support the mission, an attitude control is needed such as Attitude and Determination Control Subsystem (ADCS). This spacecraft is designed with a Micro Reaction Wheel (MRW). This is a type of reaction wheel that has a small size which fit with cubesat dimension. It consists of flywheel attached to BLDC motor and Electronic Wheel Drive (WDE). The Micro Reaction Wheel has been designed to have a minimum speed of 64021rpm with a voltage of 8V and a duty cycle of 9.95% or 4.47% and the maximum speed with a rigid of 1, 9V and a 7.55% duty cycle or 6.69%. With these results, the Micro Reaction Wheel can generate a torque of 0.74 mNm. Consume battery energy at a maximum speed of 16,67 mAh/minute.
