Accurate tracking is required for the telemetry
The environment requires operation in extended temperatures
Direct upgrade from stepper-based system
The application has demanding requirements for size and weight
The Elmo Solution The Hornet digital drive was selected because it provides a compact form factor is rated
suitable for extended environmental conditions and includes sophisticated on-board intelligence. The Hornet provides the most efficient and advanced servo control in a very compact package.
Because the majority of the installation sites are desert based or in aerial vehicles, the ability to withstand extended temperature ranges is a critical factor in selecting the drive and the other electronic components in the system. The Hornet is a member of Elmos ExtrIQ family of digital drive options. These ExtrIQ based products conform to MIL-Spec standards, not only for extended temperatures, but also for extended shock and vibration. In addition, because incremental or digital encoders are typically affected by harsh environments (temperature, shock, vibration), resolvers which are more robust in harsh environments are used. The Hornets compact, built-in resolver interface provides an additional benefit in this application.Connectivity
The Hornet is a PCB mounted device which enables an efficient and cost effective implementation. This allows the customer to simply integrate the digital drive and other
electronic systems/circuits on a single PCB board. The Hornet's compact size allows the user to mount the drive on or near the actual motor or load assembly, thus minimizing cable lengths and increasing reliability.
