The VMT-35 device is a magnetic Torquer designed specifically for small satellites attitude control. It produces a magnetic field, which is used to interact with the earth magnetic field and thus produce a torque on the satellite. This way the angular momentum of the satellite can be changed.
The VMT-35 consists of a core, made of magnetically soft material with a high permeability, with a coil made of copper wire wound around it. The coil with its core is located in a black anodized aluminium tube and encapsulated in resin to ensure isolation. The coil has a direct connection to the connector so that current and thus the magnetic field can be directly controlled.
Parameters such as geometry, number of windings, wire diameter or ohmic resistance of the torquer can be customized as needed.
The key features the VMT-35 magnetic torquer offers are
- High reliability
- Custom definable parameters
- Low hysteresis
- High linearity
- Resin encapsulated coil
- Low cost
- Compact layout
