Magnetic Torquerod for Satellites and/or 

Spacecraft Attitude Control

 

Magnetic Torquerod orient your spacecraft’s attitude and manage angular momentum onboard.

These relatively simple devices interact with the Earth’s magnetic field and create control torque, which can be adjusted to a specified value.

Combined with one or more wheels they provide all the control you need to maintain your Spacecraft attitude, from low-Earth orbit to geo-stationary orbit.

And, unlike thrusters, torquers do not use valuable consumables, are low power, and very reliable.

Alta Industries s.r.l. has teamed with IMT to provide high performance torquers and system supports that meet all your program requirements and keep your budget and schedule on target.

Our production process meets the highest standards for performance and workmanship, with excellent quality control, ISO 9001 : 2000.     
 

  

Design Features

- Mumetal core 

- Al 6061 T62 brackets 

  (custom design available)

- Resin protection encapsulates 

  the wire-wrapped core inside the housing. 

- Double insulated copper wiring 

- Wide range magnetic Linear Dipole Moment 

- Custom size and performances available 

 

Performance 

- Near to zero hysteresis 

- Excellent linearity 

- High maximum dipole moment 

 

While torquers appear to be relative simple devices they require thoughtful design and careful assembly. Microcosm’s and acceptance testing ensures that there is virtually no potential for degradation either on the ground or on–orbit. 

 

The torquer’s most critical component –its core material- has been heat-treated to ensure optimal magnetic properties. Each unit is totally encapsulated and, except for the core, made with non-magnetic components.
