Description

Magnetorquer rod for momentum dumping of LEO satellites.

The MT-P4 magnetorquer rod is an integrated solution designed for momentum dumping of LEO satellites. The core is annealed Alloy 79 wound with enameled copper winding and optimized for low power consumption at nominal magnetic dipole of 2 Am2. The MT-P4 has built-in control electronics and is simply interfaced by 28V unregulated battery voltage and redundant CAN busses. The MT-P4 comprises redundant input supply connected using diodes, redundant torquerrod windings and redundant driver electronics for enhanced reliability. The mounting brackets can be moved to accommodate various mounting features on the satellite bus.
