The REWL-30 is a 30mm high performance reaction wheel. The fully integrated reaction wheel unit is for high performance satellite attitude control for Nanosatellite missions with mission lifetime up to 5 years (minimum).

The REWL-30 wheel is an integrated 3-phase outrunner BLDC with 8 rare-earth magnets in the rotor and 6 coils in the stator. Material for the body is Al-7075-T6, rotor is made of ferritic stainless steel while the magnets are Neodymium.

The wheel is commutated by its own internal microcontroller, which runs the control loop to control speed and acceleration upon commands from the ADCS computer.

Each wheel has a I2C bus interface with CSP making them accessible to the satellite communication bus. The wheels are fitted with basic telemetry sensors: Temperature, vibration, current 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 speed.
