Summary

The Space Inventor WHL-10 is a reaction wheel suitable for attitude control of 1U-3U CubeSats with a mission lifetime of up to 5 years.

The reaction wheel consists of an integrated 3-phase outrunner BLDCs and is made of the material Al-7075-T6. There are 6 coils in the stator and 8 Neodymium magnet poles in the rotor, and ferritic stainless steel is used for the rotors.

Two hybrid precision bearings on the sides of rotor are made of ceramics for longevity and for lowering friction in space.

The speed and acceleration of the reaction wheel is controlled by the internal microcontroller based on commands from the ADCS computer. The product is previously known as REWL-30.
