WHL-50 image

Overview

Fully integrated reaction wheel unit for high performance satellite attitude control for Micro and Nano-satellite missions with mission lifetime up to 5 years (minimum). The WHL-50 wheel is an integrated 3-phase out runner Permanent magnet synchronous motor (PMSM) with 8 rare-earth magnet poles in the rotor and 6 teeth in the stator. Material for the body is Al-7075-T6, 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 vacuum conditions. 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.
