EXA MT01 Compact Magnetorquer

€1000 - €1200

With only 7.5 grams and 3.2 millimeters thickness, the MT01 Compact Magnetorquer is a vacuum core magnetic coil designed fo ADCS control in cubesat mission from 1U to 3U that boast an impressive performance compared to its small footprint over the mass, power and area budget of the spacecraft. Even with that small dimensions the MT01 is capable of greater magnetic moments, turn speeds and angular accelerations than comparable products on the market, yet the power usage is kept to a minimum: It can turn a 1U mass 90 degrees in 60 seconds using only 0.2 Watts at a LEO orbit of 500kms.

MT01 can be integrated in to our BA0x family of high capacity compact batteries and our DSA Deployable Solar Array family too, the biggest advantage of the MT01 is that it can be easily affixed anywhere on your spacecraft using a minimal area.

Every coil is tested and qualified in our own facilities and shipped with full reports and packed with additional match connectors interfaces.
