OrbiCraft Pro SXC-FW4-02 reaction wheels module is an autonomous actuators module of four flywheels with drivers and control electronics which is designed to be integrated into 3U or larger nanosatellite.

The flywheels and electronics are balanced and calibrated and provide enough momentum to rotate nanosatellite. It uses single PC/104 connection with power and CAN buses. Each fly-wheel driver can be driven separately with it’s own CAN ID.

The module is design to be used “of the shelf” with SPUTNIX SXC-MB-04-ADC controller (or later).

Features:

  • Complete 3-axis angular rate actuators for CubeSat satellite;
  • Easily integrates with SPUTNIX Orbicraft-Pro platform;
  • Four brushless DC motors with vacuum-rated bearings;
  • Wide power supply range;
  • Momentum and current control algorithms;
  • Voltage, Current and temperature sensors for each motor;
  • CAN interface for each separate driver;
  • Rich telemetry and commands protocol;
  • Bootloader with in-flight firmware update feature.

Configuration:

  • Increased maximum rotation speed and momentum;
  • CAN bus data rate.
