DESCRIPTION
The MicroWheel 4000 (MW 4000), part of MSCI’s High Performance Attitude Control product line, is a reaction wheel torque actuator and angular momentum storage device for small satellites. The 4000-series MicroWheel is for satellites requiring up to 4 Nms of momentum storage.

The MicroWheel is a “smart” sensor/actuator pair. It includes both a reaction wheel, and an optional solid-state angular rate sensor, both of which are operated locally by an embedded micro-controller. The micro-controller implements local speed and torque control loops for the reaction wheel, allowing the reaction wheel to accurately track speed or torque commands from a satellite’s attitude control computer.

MSCI is proud of the extensive flight heritage our world leading MicroWheels have gained. – more than 75 years of operational wheel-hours in LEO orbit on multiple missions.

BENEFITS
MSCI’s MW 4000 MicroWheels provide a simple, drop-in solution to satellite control. With their serial data interface, the MicroWheels perform all motor control tasks internally to generate precisely the torque requested by the Attitude Control System (ACS) computer.
