Description

The REWL-30 and 50 reaction wheels are integrated, 3-phase outrunner BLDCs with rare-earth magnets in the rotor and 6 coils in the stator. Material for the body is AL-7075-T6, the rotor is made of ferritic stainless steel while the magnets are Neodymium. The rotor is axially suspended between two hybrid ceramic high precision bearings chosen for long life and low friction in extreme conditions. Communication is done by its own internal microcontroller, which runs the control loop and acceleration upon commands from the ADCS computer.

Each wheel has a CAN bus interface with CSP making them accessible to the satellite communication bus. The wheels are fitted with basic telemetry sensors: Temperature, current, and speed.

Our recommendation for complete 3 axis control is to use the four wheels in the classic tetrahedron configuration for the benefit of both redundancy and elimination of zero crossing the wheel.
