1-inch series resolvers offers fully housed configuration
Honeywell introduced the Hawk Resolvers 1-Inch Series, Fully Housed Configuration, which provide enhanced accuracy (±7 arcmin) for precise motion control. With the launch of the Hawk Resolvers, Honeywell now offers two off-the-shelf versions, as well as resolvers that can be customized to meet specific end-user needs.
Potential defense applications for the 1-Inch Series include positioning for electro-optical systems, gimbals/communication pedestals, infrared systems, vehicle transmission systems, and test equipment. Potential space applications include positioning for satellite, satellite antenna, space station, and space vehicle solar panel arrays.
The Hawk 1-Inch Series Resolvers offer shock specification of 50 g, 11 ms, vibration specification of 15 g, 10 Hz to 2000 Hz and wide operating temperature range of -50.8 °C to 93.3 °C [-60 °F to 200 °F] which allow for use in harsh military and aerospace applications. The resolvers also feature a wide excitation voltage range of 2 V to 15 V; which allows customers to standardize on a resolver that meets their excitation voltage needs, simplifying sourcing and delivery, and saving time as well as global support.
In addition to its non-contact design, the lack of electronics, and the use of space-qualified materials, Hawk Resolvers meet multiple military/aerospace specifications: DO-160D, MIL-STD-202G, MIL-STD-810G, MIL-STD-81963B, MIL-STD-461F, and comply with space outgassing requirement SP-R0022.
The fully housed configuration with bearing/shaft has a small outer diameter of 1 inch, which allows for use in size-restricted applications. The single speed operation (1 magnetic pole pair) allows for cost-effective angle resolution over a 360°+ range, and the wide excitation frequency range of 2000 Hz to 5000 Hz provides a wide variety of choices with which to power the device. The transformation ratio of 0.45 or 1.0 offers customers two choices, increasing flexibility within the application.
The Honeywell Hawk™ 1-Inch Series Resolvers are also available with a variety of options, including:
- Custom trim designed to allow tighter accuracy;
- Connections which include custom lead wire, cable, connector on unit or connector on cable;
- Titanium housing which provides enhanced durability and resistance to corrosion; lightweight;
- Custom redundant version (two independent resolvers within the same housing) which provides reliable back-up/fail-safe in critical applications;
- Transformer for 360°+ rotation (continuous).
