Apply torque using Earth’s magnetic field.
Magnetorquers generate a commanded magnetic dipole that interacts with the local planetary field. Products range from individual rods and air coils to complete three-axis actuator boards with drivers and sensors.
These are sourcing candidates, not a confirmed Starlink supply chain.
Magnetic rods with configurable dipole, mass and length, including redundant-winding options for spacecraft attitude actuation. [3]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Compact annealed-core magnetic rods offered in multiple sizes and customizable arrangements for distributed spacecraft control. [4]
Company location: South Africa
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Digitally controlled magnetic rod with nominal and temporary boost operating modes and integrated drive functionality. [5]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Manufacturer supplies spacecraft magnetic torquers in customizable moment classes alongside magnetic sensors. [2]
Company location: Germany
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Compact three-axis magnetic-actuation assembly intended for CubeSat-class spacecraft; request the actuator and driver interface definition. [6]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Magnetic torquer using Alloy 79 core material with redundant inputs and drivers. [1]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Magnetic-actuator products include the MP42 redundant-coil unit and a separate M6P configuration; electrical values depend on the selected assembly. [7]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
Integrated magnetic-control board combines two rods, an air-core coil, embedded sensing and detumbling functionality. [8][9]
Request the configuration and current quotation from the official manufacturer; catalog presence is not evidence of stock or delivery schedule.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Compare nominal versus boost moment at a stated voltage and temperature.
Coil resistance and temperature affect power and moment; compare continuous operation and duty-cycle limits.
Determine whether drive electronics, current regulation and polarity reversal are included.
Request residual dipole, hysteresis and remanence to assess interference with magnetic sensors.
Rod length can dominate packaging; compare core rods and air coils within the actual mounting envelope.
Independent windings, inputs and drivers have different failure coverage; clarify which are duplicated.
Check continuous versus pulsed actuation, temperature sensing and heat paths.
Moment does not directly equal torque; achievable control depends on magnetic-field direction, orbit and actuator axes.
Specifications belong to the named product and configuration.
Historical published reference; obtain the current option sheet before selection.
Manufacturer pages and technical documents support the linked claims. A review date is not a publication date or stock check.
